Install power cable
▶ Check the power cable for mechanical damage. Replace damaged
cables.

Particle filter
The filter prevents particles and contamination from entering the heat
pump. Over time, the filter can become blocked and must be cleaned.
To clean the filter, the system does not need to be emptied. The filter is
integrated into the shut-off valve.
Cleaning the strainer
▶ Close the valve (1).
▶ Unscrew the cap (manually) (2).
▶ Take out the strainer and clean it by running water over it or by
pressure cleaning.
▶ Reinstall the strainer. For proper assembly, make sure that the guide
bumps fit into the recesses in the valve.

▶ Screw the cap back on (tighten handtight).
▶ Open the valve (4).
Check the magnetite indicator
After installation and startup the magnetite indicator must be checked at
more frequent intervals. If a lot of magnetic dirt is clinging to the
magnetic bar in the particulate filter and that dirt frequently causes an
alarm related to the poor flow (e.g., low or poor flow, high flow supply or
HP alarm) a magnetite filter (see list of accessories) must be installed to
avoid regular draining of the indicator. A filter also increases the
longevity of components in the heat pump as well as the remaining parts
of the heating system.

If the temperature controller is installed after commissioning the system,
it must be set in the commissioning menu as control unit for the
corresponding heating circuit ( instructions for the control unit).
▶ Before commissioning the system, make the setting for the heating
circuit at the temperature controller, if required ( instructions for
temperature controller).
▶ When commissioning the system, specify that a temperature
controller is installed as control unit for heating circuit 1 (
instructions for the control unit).
▶ Set the room temperature as specified in the instructions for the
control unit.
If a component is already connected to the EMS terminal, connect in
parallel to the same terminal according to fig. 16. If several EMS
2
modules are installed in the system, connect them according to fig. 13,
chapter 5.7.9.

Route all low voltage cables (measuring current) separately from cables
carrying 230 V or 400 V to avoid inductive interference (minimum
separation of 100 mm).
When extending temperature sensor cables, use the following conductor
diameters:
• Cable up to 20 m in length: 0.75 to 1.50 mm
• Cable up to 30 m in length: 1.0 to 1.50 mm2
The relay output PK2 is active in cooling mode and can be used to control
the cooling/heating mode of a fan convector or a heating pump, or to
control underfloor heating circuits in humid rooms.
