1. Connect the hydraulic connections to
the heat pump.
2. Check the internal tightness hydraulic
connections.
3. Thermally insulate the wires inside
the building. In case of heat pumps
with cooling function use thermal
insulation and vapor barrier.
4. Safety valve drain line through
ventilation should be connected
to the pipe with a slope to sewage
system.

Connecting the refrigerant circuit
For surface cooling systems (e.g. heating circuit in a heating system cooling mat) a
humidity switch is required (accessory additional).
Requirements for the humidity switch:
■
Electrical connection, depending on the type of humidity switch:
- 24 V (recommendation):
Connection to F11 on the controller and sensor PCB
- 230 V ~, 0.5 A:
Connection to X3.8 / 3.9 on head terminals
■
Installation in the room to be cooled on the chilled water supply (remove thermal
insulation if necessary).
■
If more rooms with varying humidity are required for the cooling circuit air, install
several humidity switches and connect them in series:
Design the switch contacts as normally closed contacts.
