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 at the highest point. 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 push-button on the
operating panel.

2. Let the pump run for approximately 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.

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

UPS3 is designed for circulating liquids in all kinds of heating
applications. 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.

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.

The speed can be controlled by a low-voltage PWM (Pulse Width
Modulation) signal.

5.3 Pumped liquids

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.

The pump is suitable for clean, thin, non-aggressive and
non-explosive liquids, not containing solid particles, fibres or
mineral oil.

• Maximum water/propylene glycol mixture is 50 %

• Maximum 10 mm

2

/s viscosity

Note: The water/propylene glycol mixture reduces the
performance due to higher viscosity.

6. Control functions

6.1 Operating panel

Fig. 12 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. 15 where II has been
selected.

Fig. 13 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. 14 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.

Fig. 15 Constant-pressure curve

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.

6.2.4 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 circulators, for instance

integrated in boilers.

6.2.5 Externally controlled signal connection: PWM input
signal profile A (heating)

The UPS3 can be controlled via a digital low-voltage pulse-width
modulation (PWM) signal. For instructions on how to set the
connection, see section 7.3 Setting the PWM input signal.

The circulator runs on constant-speed curves depending on the
PWM input signal. The speed decreases when the PWM value
increases. If PWM equals 0, the circulator runs at maximum
speed.

Fig. 16 PWM input signal profile A (heating)

6.2.6 PWM feedback signal - power consumption

The PWM feedback signal offers pump information like in BUS
systems:

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

• warning

•alarm

• operation status.

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. 17.

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,
II

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.

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

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.

9.1 Deblocking the shaft

If the pump is blocked it is necessary to deblock the shaft. The
UPS3 deblocking device is accessible from the front of the
circulator without having to demount the control box. The force of
the device is high enough to deblock circulators, which are seized
by lime, e.g. 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

TM07 0387 1518

Before, during and after the deblocking, the device is
tight and must not release any water.
