INSTALLATION
STEP 1 - INSTALL FAN - POWERED BOX
SELECT LOCATION
1. Units should be installed so that they do not come in
contact with obstacles such as rigid conduit, sprinkler
piping, Greeneld exible metal covering, or rigid
pneumatic tubing; such contact can transmit vibration
to the building structure, causing objectionable low
frequency noise.
2. Units should never be installed tight against concrete
slabs or columns, as vibration transmission is amplied
in this condition.
3. Fan powered terminals require sucient clearance for
servicing the blower/motor assembly from the bottom
of the unit, low voltage controls from the side and line
voltage motor controls or electric heat (if equipped) from
the rear (discharge end) of the unit.
Bottom access panel removal requires a minimum of 3”
minimum clearance, plus substantial horizontal clearance
to slide the access panel out of the way for service. Actual
horizontal dimensions will vary due to varying access
panels for dierent sized units. See the specic unit’s
submittal drawings for more detail.
NOTE: Be certain appropriate accommodations for
panel removal of most unit casings are large enough
to allow adequate internal service room once the
panels are removed.
A minimum clearance of 18”* is recommended for
control enclosure access. Unit control enclosure will vary
depending on which control package is used. Control
enclosure location is specied on unit submittals. Low
voltage enclosure covers are removable, not hinged.
A clearance of 36”* is recommended for line voltage motor
controls and electric heat control access. High- voltage
motor controls or electric heat control access is supplied
with hinged access doors for units with fused disconnect.
Specic location is indicated on the unit submittal.
NOTE: These recommendations do not supersede
NEC (National Electrical Code) or local codes that
may be applicable, which are the responsibility of the
installing contractor.
4. Whenever possible, fan-powered boxes should be
installed over halls or passageways (rather than over
occupied spaces) in order to limit the sound reaching
occupants.
POSITION UNIT
1. When moving boxes, use appropriate material handling
equipment and avoid contact with shaft extensions,
controls, wiring, piping, heaters, and control boxes.
2. Raise unit to position using safe mechanical equipment
and support until hanging means are attached and box
is level.

Fan Powered Terminal Units IOM
INSTALL UNIT
1. Install eld-supplied eyebolts, straphangers or bolt rod
supports as desired. Figure 5 illustrates possible unit
suspension methods. A typical installation is shown in
Figure 6.
2. Care should be taken to use hanging materials of
sucient stiness and strength, rigidly attached to the
unit. Straps should not be located on coil anges, electric
heat sections, or control boxes. When using trapeze

supports, avoid areas where access is required to side
mounted controls, or side or bottom access doors.
For best installation with trapeze supports, provide
elastomeric material between unit and supports.
3. Hangers should be securely attached to bar joist or
mounting anchors properly secured to building structure
with lugs or poured-in-place hangers. Percussion nails
are not considered adequate anchors.

3. Fan boxes should not be attached to octopus sections
immediately downstream of the unit.
4. Install optional return-air lters before operating the
unit.
5. Where construction lters were supplied with the box,
leave lters in place until installation is complete and
building is cleaned for occupancy.
STEP 3 - POWER WIRING (see Figure 7.)
1. All power wiring must comply with local codes and with
the NEC (National Electrical Code) ANSI/NFPA (American
National Standards Institute/National Fire Protection
Association) 70-1981. Disconnect switches are optional
equipment. Electrical, control and piping diagrams are
shown on the exterior labeling or on a diagram inside
the control and high-voltage enclosure covers, unless
otherwise specied in the order write-up. All units are
wired for a single point electrical connection to the
fan and electric heater (if equipped). Electric heaters
provided by Krueger are balanced by kW per stage. The
installing electrician should rotate incoming electric
service by phase to help balance overall building load.
2. All eld wiring must be provided with a safety disconnect
per NEC 424-19, 20, and 21.
STEP 2 - MAKE DUCT CONNECTIONS
1. Install supply ductwork on each of the unit inlet collars.
It is recommended that 3 duct diameters of straight duct
are supplied to the inlet of the unit. An elbow put at the
inlet of the unit will create turbulence at the inlet making
it dicult for the ow sensor to accurately measure
the airow. Check that the pressure pick-up in primary
air collar is located properly and that air supply duct
connections are airtight. Install supply ductwork on unit
inlet collar, following all accepted medium-pressure duct
installation procedures. Seal joints against leakage.
NOTE: For maximum eciency in controlling radiated
noise in critical applications, inlet ducts should be
fabricated of 24-gauge minimum sheet metal in place
of ex connections. Flex duct is extremely transparent
to radiated sound; consequently high inlet static’s (Ps)
or sharp bends with excessive pressure drop can cause
a radiated noise problem in the space. If ex duct is
used, it should be limited to the connection between
the distribution duct and the boot diuser.
2. Install the discharge duct. On units with electric heat, the
recommended minimum distance of straight duct before
any transitions, elbows or branch connections is 48”. It is
strongly recommended that lined discharge duct be used
downstream of the unit. Insulate duct as required.
11
Fan Powered Terminal Units IOM
FIGURE 7 – Typical Power Connections for Fan Powered Units with 3-Stage Electric Heat
3. Disconnect all incoming power before wiring or servicing
unit. All disconnect switches on the terminal (if equipped)
should be in the OFF position while making power
connections.
4. Units with electric heat should use copper wires rated at
least 125% of rating plate amperage. Refer to the unit’s
rating label and minimum supply circuit amps.
5. Observe wiring diagram and instructions attached to the
unit. 480-v, 3-phase units require a Wye power source
with a 4th (neutral) wire in addition to the full sized
ground wire. All units must be grounded as required by
NEC 424-14 and 250.
STEP 4 - SYSTEM SETUP AND CALIBRATION
GENERAL
The parallel fan powered terminals (KLPP, KQFP and QFV) are
designed to provide varying quantities of cold primary air
to a space in response to a thermostat demand for cooling.
For a heating demand, the fan will operate to supply ceiling
plenum air to the space. For units equipped with a heating
coil, the heater will operate as required to meet a heating
demand.
The series fan powered terminals (KLPS, KFSS, KQFS and
QFC) are designed to provide a constant airow to the space.
The air supplied to the space is a mixture of primary air and
ceiling plenum air. The fan speed is adjusted to provide
the required airow to the space. In response to a cooling
demand from a thermostat, the damper will increase the
amount of cold primary air while reducing the amount of
ceiling plenum air to decrease the temperature of the air
being delivered to the space.
Most terminal control packages provide pressure
compensation to allow pressure independent operation of
the primary air damper, regardless of changes to the available
static pressure in the supply ductwork. To balance the unit it
is necessary to set both the minimum and maximum airow
set points of the controller. The many types of control
options available each have specic procedures required
for balancing. Refer to the submittal information for these
requirements.
SET POINTS
Maximum and minimum airow set points are normally
specied for the job and specic for each unit on the job.
Default set point values are provided by the factory and can
be reset to the specic requirements in the eld. The fan
speed must be eld adjusted after all discharge ductwork
and diusers have been installed.
FIELD ADJUSTMENT OF THE MAXIMUM AND MINIMUM
AIRFLOW SET POINTS
Each fan powered terminal unit is equipped with an airow
sensor installed in the primary air inlet that measures a
dierential pressure. The relationship between the airow
probe pressure and the corresponding airow is shown in
the airow sensor graph. See Figure 8. The corresponding
chart for specic probe is attached to each unit.

START-UP
SYSTEM CALIBRATION OF THE INLET AIRFLOW SENSOR
To achieve ecient pressure independent operation, the
velocity sensor and averaging ow probe must be calibrated
to the controller. This will ensure that airow will be accurate
for all terminals at system start-up.
System calibration is accomplished by calculating a ow
coecient that adjusts the pressure fpm characteristics.
The ow coecient is determined by dividing the ow for a
given unit (design air volume in cfm), at a dierent velocity
pressure of 1.0 in. wg, by the standard pitot tube coecient
of 4005. This ratio is the same for all sizes, if the standard
averaging probe is used.
Determine the design air velocity by dividing the design air
volume (the ow at 1.0-in. wg) by the nominal inlet area (sq.
ft). This factor is the K factor.
Krueger inlet areas are shown in the table. The design air
volume is shown in this table. It can be determined from
Table 7 that the average design air velocity for units is equal
to 2660 fpm at 1.0-in. wg.
8. Connections to the coil, when used, must be checked.
9. Water control valve, if used, must be checked.
IMPORTANT: Before proceeding with start-up, be
certain that voltage, frequency, and phase correspond
to unit specications. Unless noted, all fan motors are
60 Hz, 115, 208/240, or 277 v, single-phase ac. electric
heat, the electric heat voltage may exceed the blower
motor voltage requirement. Excessive voltage to the
fan box may seriously damage it. Verify that the DDC (if
equipped) are receiving 24-v ac, –15%, +20%
INITIAL START-UP PROCEDURES
NOTE: The following steps MUST be followed in order to
properly operate and service this unit.
1. Disconnect all electrical power to the unit. Failure to
disconnect the power to the fan box prior to checking
and/or servicing the fan box could result in a serious
injury.
2. Verify that the fan box is installed level, and that adequate
mounting support has been provided.
3. Remove motor access panel from the bottom of the fan
box, and also remove the control panel cover.
4. Test the fan motor setscrew. The setscrew should t
tightly, but it may have come loose during shipment or
installation.
5. Rotate the blower by hand to ensure proper clearance
between the blower and the blower housing.
6. Check the fan box for loose berglass insulation,
especially on the electric heater elements or the hot
water coils (if these accessories are installed).
7. Check the control enclosure and remove any debris.
8. Check the induced air inlet lter (if provided) for
obstructions, and verify the lter is securely in place.
9. Verify the main power supply to the connection to the
fan box for proper voltage. If the fan box is installed with
electric heat, the electric heat voltage may exceed the
blower motor voltage requirement. Excessive voltage to
the fan box may seriously damage it. Verify that the DDC
(if equipped) are receiving 24v-ac, –15%, +20%.Identify
the control system supplied.
10. Check all control connections (and/or electric) for proper
installation.
11. Connect electrical power.

Fan Powered Terminal Units IOM
BALANCING KRUEGER FAN TERMINALS
Krueger fan terminal units contain primary air dampers,
which, under the control of a volume controller, regulate the
amount of cold air distributed to the space.
BALANCING SERIES FLOW UNITS
KLPS, KFSS, KQFS & QFC series ow terminals direct all
primary air through the unit fan. The terminal is designed
to operate with the fan supplying airow equal to or greater
than the airow supplied by the VAV damper. To balance the
unit, therefore, it is necessary to rst set the fan ow, and
then the VAV damper (primary) ow.
Each control option has specic procedures required for
balancing the unit, but some steps are common to all KLPS,
KFSS, KQFS & QFC units. The fan box adjustments described
below must be made in conjunction with the adjustments
described in the Speed Controller section, and Control
Adjustments section. The VAV damper airow may be set
at the factory, but the fan airow must be set in the eld as
described below.
SETTING FAN AIRFLOW
NOTE: If the unit has electric heat or hot water heat,
temporarily disable these functions before balancing
the fan. If unit has optional electric heat disconnect
downstream of fan motor connections to power, open
disconnect. If unit does not have optional electric
heat disconnect, remove one electric heat power line
connection. Be sure to insulate loose line from ground
wire or other wires.
1. Set the controller to provide heating airow demand only.
Typically, this is accomplished by setting the thermostat
to the highest possible temperature setting. NOTE: A
minimum of 0.1” w.g. downstream static pressure is
required in the duct to ensure proper heater operation.
2. Determine that the VAV valve is fully closed and that the
fan is rotating in the proper direction. (If the VAV damper
is open when the fan is started and there is primary air in
the system, the fan may start and run backward.)
3. Using a ow hood or duct traverse, determine the
delivered fan airow (cfm). NOTE: Both ow hood and
duct traverse are subject to measurement errors. Be sure
that all applicable measurement precautions are taken.
4. Compare the actual cfm in heating mode to the designed
airow. If there is a minimum setting for the VAV damper
in heating mode (as recommended by ASHRAE [American
Society of Heating, Refrigeration, and Air Conditioning
Engineers] Standard 62), this quantity is included in
the total measured heating airow to determine if the
desired induction airow level has been met.
5. Adjust the fan SCR at unit control box to achieve the
desired airow rate. Refer to the performance data
tables (Tables 8 and 9) to ensure airow through electric
heaters meets the requirements before operating the
heater. Setting of VAV (Primary) Airow
ADJUSTMENT OF SET POINTS
Each KLPS, KFSS, KQFS and QFC unit, supplied with
controls, is equipped with a pneumatic or electronic volume
controller which regulates the quantity of cold primary
air entering the terminal and the conditioned space. If
required airow levels are specied with the job order, the
minimum and maximum cfm levels will be set at the factory
where applicable. If minimum and maximum levels are not
specied, a default value of 0 is used for minimum setting
at the factory. Other settings of minimum and maximum
primary airow must be set in the eld. Airow (cfm) ranges
for the primary air damper are shown in Tables 8 and 9. The
minimum primary airow (other than zero) is the minimum
ow rate controllable by the unit volume controller. The
primary air damper can be set at zero for shuto or at the
minimum cfm listed.
FIELD ADJUSTMENT OF MINIMUM AND MAXIMUM AIRFLOW
SET POINTS
Each KLPS, KFSS, KQFS and QFC unit is equipped with a
centerpoint averaging airow sensor, which provides an
amplied dierential pressure that is proportional to the
unit airow. Output from this sensor is used to provide a
ow signal to both pneumatic and electronic controls. Unit
airow (cfm) can be read directly from the airow sensor
labels on the unit (refer to Figure 8, Flow Chart).
1. With the unit airow from the fan set, turn on primary
(VAV) air supply.
2. To set cfm in the eld, connect a gage to the ow probe at
the provided ‘T’ taps, and check the dierential pressure.
(Alternately, the total ow may be measured, and the
previously determined fan induction ow rate may be
subtracted from the total ow to determine VAV ow.
However, for low primary settings, this may not be as
accurate as the ow tap method.)
3. If a minimum VAV ow is required in heating mode, adjust
the volume until the dierential pressure corresponds to
the cfm required.
4. Set the controller to provide maximum cooling demand.
This is typically accomplished by rst setting the
thermostat to the lowest possible temperature setting.
a. In most series fan boxes, the primary airow rate is
set so the maximum primary CFM is equal to the fan
CFM; in these cases, adjust the volume controller until
a balance is achieved between fan-induced airow
and primary airow. When a balance exists, a strip of
paper hung at the induction port should hang straight
down, and neither be blown in or out of the unit.
b. Primary CFM airow is less than the fan induction ow
cfm, adjust the volume controller until the dierential
pre ss ure (measu red t hrough t he o w prob e as des cr ib ed
above) corresponds to the cfm required. Verify that
induction exists through the inlet ports, using the paper
strips as described above. When induction exists, the
paper strip should be pulled into the unit.
5. Return all reheat options to normal connections.
6. Cap the ‘T’ taps.
7. Reset the thermostat to a normal setting.
NOTE: It is normal for the total airow to the room to
increase slightly in full cooling mode.

BALANCING PARALLEL FLOW UNITS
The KLPP, KQFP, and QFV parallel fan terminals are designed
to operate with the fan supplying air equal to 40 to 60% of
the VAV damper maximum primary air setting. Adjustments
to the parallel units fan should be made with the primary
air closed o. Refer to unit capacity tables to ensure
airow through the electric heater meets the minimum
requirements before operating heater.
Each control option has specic procedures required for
balancing the unit, but some steps are common to all parallel
fan units, as described below.
To balance parallel fan unit:
SETTING FAN AIRFLOW
NOTE: If the unit has electric heat or hot water heat,
temporarily disable these functions before balancing
the fan.
If unit has optional electric heat disconnect downstream of
fan motor connections to power, open disconnect. If unit
does not have optional electric heat disconnect, re-move
one electric heat power line connection. Be sure to insulate
loose line from ground wire or other wires.
1. Set the controller to provide heating airow demand only.
Typically, this is accomplished by setting the thermostat
to the highest possible temperature setting.
NOTE: A minimum of 0.1” w.g. downstream static
pressure is required in the duct to ensure proper
heater operation.
2. Determine that the VAV damper is fully closed. This may
require a temporary override of the VAV controller. Do
not adjust minimum and maximum cfm set points at this
time.
3. Using a ow hood or duct traverse, determine the
delivered fan airow (cfm).
NOTE: Both ow hood and duct traverse are subject
to measurement errors. Be sure that all applicable
measurement precautions are taken.
4. Compare the required design cfm in heating mode to the
actual delivered airow. If there is a minimum setting for
the VAV damper in heating mode (as recommended by
ASHRAE [American Society of Heating, Refrigeration, and
Air Conditioning Engineers] Standard 62), this quantity is
included in the total measured airow.
5. Adjust the fan SCR at unit control box to achieve the
desired airow rate.
SETTING OF VAV (PRIMARY) AIRFLOW
ADJUSTMENT OF SET POINTS
Each parallel fan unit is equipped with a pneumatic or
electronic volume controller that regulates the quantity of
cold primary air entering the terminal and the conditioned
space. If required airow levels are specied with the job
order, the minimum and maximum cfm levels will be set
at the factory. If minimum and maximum levels are not
specied, a default value is used. Other settings of minimum
and maximum primary airow must be set in the eld.
Airow (cfm) ranges for the primary air damper are shown
in Tables 11, 12 and 13 for KQFP, QFV and KLPP units. The
minimum primary airow (other than zero) is the minimum
ow rate controllable by the unit volume controller. The
primary air damper can be set at zero for shuto or at the
minimum cfm listed.
18
Fan Powered Terminal Units IOM
FIELD ADJUSTMENT OF MINIMUM AND MAXIMUM AIRFLOW
SET POINTS
Each parallel fan unit is equipped with a four quadrant
multi-point center averaging airow sensor that provides
an amplied dierential pressure that is proportional to
the unit airow. Output from this probe is used to provide a
ow signal to both pneumatic and electronic controls. Unit
airow (cfm) can be read directly from the ow probe on the
unit.
1. After the unit airow from the fan has been set, turn on
primary (VAV) air supply and turn o the fan.
2. To set cfm in the eld, connect a gage to the ow probe
and check the dierential pressure.
3. If a minimum VAV ow is required in heating mode, adjust
the volume controller until the dierential pressure
corresponds to the cfm required.
4. Some control sequences allow the fan to start before the
VAV damper reaches minimum setting, for an overlapping
of fan and VAV ow. For these sequences, after controller
min airow has been adjusted, the total airow with
both fan and primary airow should be checked. For
sequences that call for the fan to start as the rst stage
of heat, the cooling minimum cfm can be veried at the
diuser. Setting the minimum control point will typically
require careful adjustment of the thermostat to create a
minimum cooling demand signal.
a. Set the controller to provide maximum cooling
demand. This is typically accomplished by setting
the thermostat to the lowest possible temperature
setting. For most control sequences, this will cause
the fan to shut o.
b. Adjust the volume controller until the dierential
pressure (measured through the ow probe as
described above) corresponds to the cfm required.
6. Return all reheat options to normal connections.
7. Cap the ends of the inlet ow sensors.
8. Reset the thermostat to a normal setting.

SPEED CONTROLLER
Each Krueger fan powered air terminal unit is equipped with
a fan SCR speed controller, located on the bottom of the
control box. The SCR can be adjusted in the eld. (The QFC,
size 7 unit has 2 SCR speed controllers, one for each fan. One
SCR is located in the standard position at the bottom of the
control box; the other is at the top of the control box.)
CAUTION: The minimum stop on the speed controller
is factory set at an internal minimum stop to prevent
damage to the motor. Do not attempt to override this
minimum stop or electrical damage to the fan motor
may result.
The fan airow output is dependent on the setting of the
controller and the downstream static resistance.
TO INCREASE THE FAN SPEED (RPM)
Turn the slotted adjustment on the controller clockwise
toward the “HI” marking printed on the controller faceplate.
(Refer to Figure 9.)
TO DECREASE THE FAN SPEED (RPM)
Turn the slotted adjustment on the controller clockwise
toward the “LO” marking. (Refer to Figure 9.)

SETTING FAN AIR FLOW WITH ECM MOTORS
Several terminal unit models are available with ECM motors
for easy balancing. These motors supply a determined
amount of air regardless of static pressure from ductwork
layout or air distribution. The ECM motors are programmed
to provide a maximum CFM depending on model and unit
size. The motors are then set to provide the desired CFM as
a proportional amount of the maximum. The proportion can
be set by several options:
MANUAL SPEED CONTROL (CONTROL OPTION 6)
Manual speed controlled units are manually operated
with a digital readout on the ECM controller (see Figure
10). The digital readout provides a percent of maximum.
A fan adjustment knob is rotated until the desired percent
is displayed. After 20 seconds from nal adjustment, the
controller display will alternate between percent and motor
RPM’s. See Tables 14-28 for the percent required for desired
CFM.
REMOTE SPEED CONTROL, 0-10Vdc (0-20mA) INPUT
(CONTROL OPTION 7)
The board is factory set to accept a 0-10Vdc signal to control
the air ow between 0% and 100% as shown in the chart
in Figure 11. This option does not allow for on/o control.
Setting the jumper to the “Opt” position as shown in the
“Jumper Setting” in Figure 11 sets the control signal to
0-10Vdc signal.
REMOTE SPEED CONTROL, 2-10Vdc (4-20mA) INPUT
(CONTROL OPTION 8)
Another option is to have the board factory set to allow for
on/o control by setting the jumper on to the “P” position.
This setting uses a 2-10Vdc control signal range with a
voltage signal under 2Vdc turning the motor o . See gure
11 for graph of operating range.
Note: Both Remote Speed Control Options provide a
manual Override for eld setting the ECM motor without
being connected to a DDC controller. If a DDC controller
is connected, adjusting the manual override will lock out
the automation signal for 15 minutes.

OPERATION SEQUENCES
1. During maximum thermostat cooling demand, the
primary air damper will open in the maximum airow
setting providing cold primary air at the preset maximum
volume. Accessory coils, if supplied, are o, and the unit
should discharge primary air only.
2. When the thermostat modulates between maximum
cooling and satised set point, the primary air damper
responds by proportional settings. Accessory coils, if

supplied, are o. The KLPS, KFSS, KQFS and QFC units
only will be inducing plenum air and mixing it with the
cold primary air. The KLPP, QFV and KQFP fan will not
induce any plenum air at this point.
3. When the thermostat is modulating between maximum
heating demand and satised setpoint, the primary air
damper will be at the minimum air volume setting. A
maximum amount of plenum air is induced at this point.
In sequence, the rst and second stages of electric reheat
will energize, if supplied. If hot water heating coils are
supplied, they will either open fully or modulate open.
4. During thermostat demand for maximum heating,
primary air will ow through the unit at the preset
minimum setting, maximum amount of plenum air will
be induced, and heating coils, if supplied, are full on. See
Table 33 for Pneumatic Control Troubleshooting.
5. Adjust the “HI STAT” knob, with a 15 psi thermostat signal,
to obtain the desired airow setting. Depending on the
control sequence desired, the “HI STAT” knob will vary
either the minimum setting or the maximum setting as
follows:
DANC — “HI STAT” knob adjusts the maximum setting
RANC — “HI STAT” knob adjusts the minimum setting
DANO — “HI STAT” knob adjusts the maximum setting
RANO — “HI STAT” knob adjusts the minimum setting
6. To adjust the thermostat reset start point, remove gage
port (“G”) cap and attach a 0 to 30 psi pressure gage
and note the pressure reading. Adjust the thermostat
pressure to the controller, “T” port to the desired start
point. Adjust the “RESET START” knob until the gage
pressure begins to change slightly. Remove pressure
gage and replace cap.
7. To adjust the thermostat reset span from standard 5
psi, remove gage port (“G”) cap and attach a 0 to 30 psi
pressure gage and note the pressure reading. Adjust
the thermostat pressure to the controller “T” port to the
desired start point. Adjust the “RESET SPAN” knob until
the gage pressure equals the desired reset span. Remove
gage and replace cap.
8. To change logic from a given sequence to another, follow
the steps below:
a. To change from N.O. to N.C. or from N.C. to N.O.,
loosen the “damper” dial screw and rotate the dial
until the desired damper position indicator is aligned
with the arrow. The VAV damper must be physically
changed to desired position.
b. To change from DA to RA or from RA to DA, no
conguration changes are required — use the
appropriate calibration procedures from above.
9. Reconnect the power to the blower motor on the KLPP,
QFV & KQFP units.
NOTES:
1. The multi-function control system uses a Krueter
CSC 3000 series velocity controller with a rated air
consumption of 1.00 SCFH at 20-psi main air pressure.
2. The maximum and minimum limits are both changed
when adjusting the center knob. The center knob should
always be set rst.

ANALOG CONTROLS
INSTALLATION AND BALANCING PROCEDURES
The Analog Electronic Control System is a pressure
independent volume reset control that uses a KMC CSP-4702
controller-actuator (see Fig. 13).
Adjustments for the minimum and maximum airow
settings are made at the thermostat. The thermostat (CTE-
5202) operates on a 16 VDC power supply from the CSP 4702
controller and outputs a 0 to 10 VDC signal on the AO1 and
AO2 terminals. AO1 is used as the cooling output and AO2 is
used as the heating output.
THERMOSTAT INSTALLATION
For proper operation, mount the thermostat on an interior
wall. Do not mount the thermostat in a location that will
cause it to be aected by direct sunlight or other heat or cold
sources. The thermostat should be clear of all obstructions
so it can properly sense the room temperature. Complete
rough-in wiring at each location prior to thermostat
installation. Cable insulation must meet local building codes.
1. Remove thermostat cover. If the thermostat is locked on
the back plate, turn the two hex screws in on the bottom
of the cover (in the two outermost holes) in the back plate
CLOCKWISE until they clear the cover. Do not remove
these screws completely. Swing the thermostat up and
away from the back plate to remove it.
2. Route the wires through the opening in the back plate.
Figure 13: CSP-4702 Controller/Actuator
3. Install the back plate directly to the junction box using
the screws supplied with the thermostat. Verify the hex
screws used for securing the cover are located at the
bottom before installing.
4. Connect the wires to the terminal block. Refer to the
wiring diagram located on the inside cover of the control
enclosure of each unit showing the wiring terminations.
The wiring schematic can also be found on the control
sequence submittal found on the Krueger website.
5. Replace the thermostat cover. Turn the two hex screws
COUNTER CLOCKWISE until they are ush with the
bottom cover and secure it to the back plate.
PROGRAMMING THERMOSTAT
1. The thermostat has three sequences that are selectable
from the display screen. To access the conguration menu
on the thermostat, press and hold the Up and Down
arrows for 10 seconds until the display starts ashing
“LIMITS”. Use the Up and Down arrows to scroll between
the dierent menu options or set a specic value. Use the
Setpoint button to select a menu or set a value.
2. To set the minimum and maximum airow limits, Use
AO1 Min and AO1 Max or AO2 Min and AO2 Max. Use the
Table 34 below to determine thermostat setting for the
CFM per inlet size.
3. For details on how to program the thermostat for each
control sequence see the specic control sequence
submittal. The control sequence submittals can be at the
Krueger Website: www.krueger-hvac.com.
NOTE: Adjustments for the minimum and maximum airow settings are made at the thermostat. The thermostat (CTE-5202) operates on a 16 Vdc power supply from
the CSP 4702 controller and outputs a 0 to 10 Vdc signal on the AO1 and AO2 terminals. AO1 is used as the cooling output and AO2 is used as the heating output."

ANALOG CONTROL TROUBLESHOOTING
The following troubleshooting guide is directed towards
single duct cooling applications, the same concepts can be
applied to other congurations.
NOTE: For about 15 seconds after power is applied, no
rotation occurs and one or both of the LEDs will ash.
CONTROLLER
1. Check that the shaft moves freely. (Press and hold the
actuator release clutch and manually rotate the shaft.)
2. Check wiring. (See Wiring Issues section below.)
3. Check for a tripped circuit breaker to the transformer, for
proper supply voltage from the transformer (or power
supply), and for enough capacity (VA) for all connected
devices.
4. Check that the direction jumper is in the proper position.
5. Check the polarity and level of the input signal from the
thermostat.
WRONG ROTATION DIRECTION OR STROKE RANGE
1. Check the position of the direction jumper.
2. Check the Min and Max ow limits on the thermostat
3. Check the adjustable stop position.
NO PRESSURE OUTPUT SIGNAL FROM INLET SENSOR
1. Check the wiring.
2. Check air ow and sensor. Tubing should be free of kinks
and restrictions. Sensor must be oriented in the correct
airow direction.
WIRING ISSUES
1. Check for correct wiring at unit and thermostat.
2. At the Controller, verify 24 VAC at terminals “~” (phase)
and “-” (ground). Tolerance can be –15% to +20% (20.4 to
28.8 VAC).
3. Verify 16 VDC at terminals “16 VDC” and “COM”
a. Tolerance is 15.0 to 17.0 VDC power supply to
thermostat.
b. If not correct, disconnect thermostat and recheck.
c. If still incorrect, replace CSP controller.
4. Check “Requested Flow” voltage on terminal “2-10 IN” and
“COM“.
e. Use Table 7 to correlate into cubic feet per minute
(CFM)
f. If reading is not what is desired, see “calibration to
adjust thermostat.
NOTE: Never jumper terminal 16 VDC to “-” as this would
cause a short, and possibly damage the power supply
NOTE: When using the same transformer for more than
one control, the phase and ground must be consistent
with each device.
WATER VALVE INSTALLATION
WARNING: Disconnect power before wiring or electrical
shock and personal injury could result.
Water valves are eld supplied. Most control manufacturers
oer three dierent hot water valve applications; on/o
and oating point, and proportional control. The controls
contractor should provide water valve specs used on
controls supplied by others. To connect the eld-supplied
water valves to the controller, refer to the wiring labels for
the control package.
SERVICE
CONTROLS
No periodic preventive maintenance is necessary.
FAN MOTOR AND WHEEL
The fan motor and wheel are accessible from the bottom of
the unit. Remove the bottom panel to check the wiring or
remove the fan wheel or motor.
The PSC motors are equipped with long life sleeve bearings
with non-detergent SAE (Society of AutomotiveEngineers)20
oil. Do not add oil to motors.
NOTE: The EC motor has permanently lubricated ball
bearings that require NO maintenance.
TO CHECK WIRING (REFER TO FIG 14-16, NEXT PAGE)
The PSC motor is connected by quick-connect terminals to
the capacitor (brown wire), the housing wire (green ground
wire), and the control box (black wire and white wire). Verify
that the fan motor wiring is correc t as shown in these gures.

TROUBLESHOOTING
To remove the fan motor and wheel:
1. Disconnect motor wiring. Note connections.
2. The fan motor and wheel assembly is attached to the
discharge panel with 4 hex nuts.
3. Remove the motor by removing the 3 screws that attach
the torsion ex or belly band mounts to the inlet ring.
4. Remove wheel by unscrewing the hub set screws that are
accessed through the open end of the wheel.
FAN MOTOR WIRING
Refer to the fan motor wiring details shown on the wiring
diagram attached to the unit. Failure to reconnect the fan
properly can cause damage to the motor and/or serious
personal injury.
FAN MOTOR MAINTENANCE
Unit motors are equipped with permanently lubricated
bearings. Inspect fan and motor assembly for accumulation
of dust and dirt as required by operating environment. Clean
as necessary.
IF FAN MOTOR DOES NOT RUN:
1. Make sure that there is free rotation of blower wheel.
2. Remove fan packing.
3. Verify that there is no freight or installation damage.
4. Check for proper unit power.
5. Disconnects should be on, and check optional fusing.
6. Check for proper control signal, pie switch setting, proper
air control 24 vac at fan contactor, and that the coil is
energized.
IF FAN MOTOR RUNS, EXCESSIVE NOISE:
1. Make sure the blower, and all components have no
clearance problems and are securely attached.
2. Verify the integrity of ductwork, make sure there are no
leaks or loose connections rattling diusers or balancing
dampers.
3. Conrm that the maximum CFM not too high, or discharge
static pressure is too low. If fan motor runs, insucient
airow:
4. Check for ductwork restrictions, dirty air lters, and
clogged water coils.
5. Re-adjust fan speed control.
6. Discharge static pressure too high.
IF REPAIR OR REPLACEMENT IS REQUIRED:
1. Motor and fan should be removed as an assembly.
Disconnect all power before servicing.
2. Remove the four hex nuts from the mounting lugs holding
the fan assembly to the discharge panel, and lower the
assembly. NOTE: Do not allow assembly to hang from
wiring.
3. Loosen the setscrew if removing motor from blower.
4. Hold the blower wheel to the motor shaft. Remove the
three screws holding motor to the fan housing, and slide
motor and fan housing apart. Reverse the procedure for
assembly.
NOTE: Over-tightening motor mounting screws may
crush isolation bushings, and cause excessive fan noise
and wear.
