4. Starting up the product

4.1 Before startup

Do not start the pump until the system has been filled with liquid

and vented. Make sure that the required minimum inlet pressure

is available at the pump inlet. See section 10. Technical data.

When using the pump for the first time, the system must be

vented. See section 4.3 Venting the pump. The pump is

self-venting through the system.

4.2 Starting up the pump

4.3 Venting the pump

Fig. 7 Venting the pump

Small air pockets trapped inside the pump may cause noise when

starting up the pump. However, because the pump is self-venting

through the system, the noise ceases over a period of time.

To speed up the venting process, do as follows:

1. Set the pump to speed III using the button on the operating

panel.

2. Let the pump run for minimum 30 minutes. How fast the pump

is vented depends on the system size and design.

When you have vented the pump, that is when the noise has

ceased, set the pump according to the recommendations. See

section 6. Control functions.

5. Product introduction

5.1 Product description

UPS3 can be used as stand-alone or integrated circulator pump

in existing systems as replacement or in new systems with either

variable or constant flow rate.

The speed can be controlled by a low-voltage PWM (Pulse Width

Modulation) signal.

High-efficiency ECM (Electronically Commutated Motor) pumps,

such as UPS3, must not be speed-controlled by an external

speed controller varying or pulsing the supply voltage.

5.1.1 Model type

These installation and operating instructions cover UPS3. The

model type is stated on the packaging and nameplate.

5.2 Applications

The pump is designed for circulating liquids in all heating

systems. The pumps are suitable for the following systems:

• Systems with constant or variable flows where it is desirable to

optimise the pump duty point.

• Installation in existing systems where the differential pressure

of the pump is too high during periods of reduced flow

demand.

• Installation in new systems for automatic adjustment of the

performance to flow demands without the use of bypass

valves or similar expensive components.

5.3 Pumped liquids

The pump is suitable for clean, thin, non-aggressive and

non-explosive liquids, not containing solid particles, fibres or

mineral oil.

In heating systems, the water must meet the requirements of

accepted standards on water quality in heating systems, for

example the German guideline VDI 2035.

Mixtures of water with antifreeze media such as glycol with a

kinematic viscosity lower than 10 mm2/s (10 cSt). When selecting

a pump, the viscosity of the pumped liquid must be taken into

consideration. If the pump is used for a liquid with a higher

viscosity, the hydraulic performance of the pump is reduced.

6. Control functions

6.1 Operating panel

Fig. 11 Operating panel

The operating panel shows the following:

• The control mode, after pressing the button

•Alarm status

6.1.1 Alarm or warning

If the pump has detected one or more alarms or warnings, the

first LED switches from green to red. When the fault has been

resolved the operating panel switches back to operating status.

See section 9. Fault finding the product.

6.2 Control modes

The pump has seven different control modes. Learn more about

them in the following sections.

6.2.1 Constant curve or constant speed, I, II or III (factory

setting)

At constant-curve or constant-speed operation, the pump runs at

a constant curve. The pump performance follows the selected

performance curve, I, II or III. See fig. 14 where II has been

selected.

Fig. 12 Constant-curve/-speed curve

The selection of the constant-curve or constant-speed setting

depends on the characteristics of the heating system in question.

6.2.2 Proportional pressure I, II

In proportional-pressure mode the pump performance follows the

selected performance curve I or II and adjusts the pump

performance to the actual heat demand in the system following

the proportional-pressure curve.

Fig. 13 Proportional-pressure curve

* Proportional pressure mode is not recommended in heating

systems that include an automatic bypass valve to ensure a

minimum flow for the heating appliances.

6.2.3 Constant pressure I, II

In constant-pressure mode the pump follows the selected

constant-pressure curve I or II, adjusts the pump performance to

the actual heat demand in the system following the selected

constant-pressure curve.

6.2.4 Changing from recommended to alternative pump

setting

Heating systems are relatively slow systems that cannot be set to

the optimum operation within minutes or hours.

If the recommended pump setting does not give the desired

distribution of heat in the rooms of the house, change the pump

setting to the shown alternative.

6.2.5 Selecting the control modes

Proportional pressure

We recommend proportional-pressure mode in variable flow

systems with relatively large pressure losses in the distribution

pipes such as:

• two-pipe heating systems with thermostatic valves and long

distribution pipes

• two-pipe heating systems with thermostatic valves and high

pressure losses in system parts with total flow

• primary circuit pumps in systems with large pressure losses in

the primary circuit.

Note: Proportional-pressure mode is not recommended in

heating systems that includes an automatic bypass valve to

ensure a minimum flow for the heating appliances.

Constant pressure

We recommend constant-pressure mode in variable flow systems

with relatively small pressure losses in the distribution pipes such

as:

• two-pipe heating systems with thermostatic valves and

dimensioned for natural circulation (former gravity systems)

• two-pipe heating systems with thermostatic valves and low

pressure losses in system parts with total flow

• one-pipe heating systems with thermostatic valves or pipe

balancing valves

• underfloor heating systems with zone valves

• primary circuit pumps in systems with small pressure losses in

the primary circuit.

Constant curve

We recommend constant-curve mode in constant-flow systems,

where both a constant flow rate and a constant head are required,

such as:

• heat surfaces

• replacement for uncontrolled circulator pumps, for instance

integrated in boilers.

6.3 Control signal

The pump can be controlled via a digital low-voltage pulse-width

modulation (PWM) signal.

The square-wave PWM signal is designed for a 100 to 4,000 Hz

frequency range. The PWM signal is used to select the speed

(speed command) and as feedback signal. The PWM frequency

on the feedback signal is fixed at 75 Hz in the circulator pump.

For instructions on how to set the connection, see section

7.1 Setting the PWM input signal.

Duty cycle

d % = 100 x t/T

Example

Fig. 15 PWM signal

6.3.1 Interface

The pump’s interface consists of an electronic part connecting the

external control signal to the circulator pump. The interface

translates the external signal into a signal type that the

microprocessor can understand.

In addition, the interface ensures that the user cannot get into

contact with dangerous voltage if touching the signal wires when

power is connected to the circulator pump.

Note: "Signal ref." is a signal reference with no connection to

protective earth.

6.3.2 PWM input signal profile A (heating)

The pump runs on constant-speed curves depending on the PWM

input signal. The speed decreases when the PWM value

increases. If the PWM signal equals zero (0 VDC), the pump will

switch to the control mode selected before connecting to a PWM

signal.

Fig. 17 PWM input signal profile A (heating)

6.3.3 PWM feedback signal

The PWM feedback signal offers pump information like in bus

systems:

• current power consumption (accuracy ± 2 % of PWM signal)

• warning

•alarm.

Alarms

Alarm output signals are available because some PWM output

signals are dedicated to alarm information. If a supply voltage is

measured below the specified supply voltage range, the output

signal is set to 75 %. If the rotor is locked due to deposits in the

hydraulics, the output signal is set to 90 % because this alarm

has a higher priority. See fig. 18.

The pump runs at a constant speed and consequently on a constant curve.

At speed II, the pump is set to run on the intermediate curve under all operating conditions.

III

Constant curve or constant

speed III (factory setting)

The pump runs at a constant speed and consequently on a constant curve.

At speed III, the pump is set to run on the maximum curve under all operating conditions.

Quick venting of the pump can be obtained by setting the pump to speed III for a short

period.

Proportional-pressure mode I,

The duty point of the pump will move up or down on a proportional-pressure curve,

depending on the heat demand in the system.

The head (pressure) is reduced at falling heat demand and increased at rising heat demand.

Constant-pressure mode I, II

The duty point of the pump will move out or in on a constant-pressure curve, depending on

the heat demand in the system.

The head (pressure) is kept constant, irrespective of the heat demand.

7.1 Setting the PWM input signal

To enable the external control mode (PWM profile A), you need a

signal cable connected to an external system. The cable

connection has three conductors: the signal input, the signal

output and the signal reference.

The cable is not supplied with the pump but can be ordered as an

accessory.

Fig. 20 Mini superseal plug

Set the signal connection

1. Make sure that the pump is turned off.

2. Locate the PWM signal connection on the pump.

The three pins inside the signal connection are not energised.

3. Connect the signal cable with the mini superseal plug.

4. Switch on the power supply.

5. The pump automatically detects if a valid PWM signal is

available after which it enables the control mode on the pump.

See fig. 8. If the pump does not detect a PWM signal or if the

signal equals 0, the pump will switch to the control mode

9. Fault finding the product

If the pump has detected one or more alarms, the first LED

switches from green to red. When an alarm is active, the LEDs

indicate the alarm type as defined in fig. 22.

When there is no active alarm anymore, the operating panel

switches back to operating status and the first LED switches from

red to green.

Fig. 22 Fault finding table

9.1 Deblocking the shaft

If the pump is blocked it is necessary to deblock the shaft. The

pump deblocking device is accessible from the front of the pump

without having to demount the control box. The force of the

device is high enough to deblock pumps, which are seized by

lime, for example if the pump has been turned off during summer.

Course of action:

1. Switch off the power supply.

2. Close the valves.

3. Locate the deblocking screw in the centre of the control box.

Use a star screwdriver with a size 2 Phillips tip to push the

deblocking screw inwards.

4. When the screw can be turned counterclockwise, the shaft

has been deblocked. Repeat step 3, if necessary.

5. Switch on the power supply.

Fig. 23 Deblocking the shaft

If multiple alarms are active at the same time, the

LEDs only show the error with the highest priority.

The priority is defined by the sequence of the table.

10. Technical data

To avoid condensation in the stator, the liquid temperature

must always be higher than the ambient temperature.

Reduced supply voltage

The pump operation is ensured above 160 VAC with

reduced performance. If the voltage falls below 190 VAC,

a low-voltage warning is sent via the PWM signal. If the

voltage falls below 150 VAC, the pump stops and shows

an alarm.

11. Performance curves

Each pump has its own performance curve.

A power curve, P1, belongs to each performance curve. The

power curve shows the pump power consumption in watt at a

given performance.

11.1 Curve conditions

The guidelines below apply to the performance curves on the

following pages:

• Test liquid: airless water.

• The curves apply to a density of ρ = 983.2 kg/m

and a liquid

temperature of 60 °C.

• All curves show average values and must not be used as

guarantee curves. If a specific minimum performance is

required, individual measurements must be made.

• The curves for speeds I, II and III are marked.

• The curves apply to a kinematic viscosity of

 = 0.474 mm

(0.474 cSt).

• The EEI values obtained according to EN 16297 part 3.
