3.4 Function
Liquid refrigerant is evaporated (evaporator), the energy
for this process is environmental heat and comes from
the outside air. The gaseous refrigerant is compressed
(compressor), this causes the pressure to rise and there-
fore the temperature too. The gaseous refrigerant at a
high temperature is liquefied (condenser).
The high temperature is hereby discharged to the
heating water and is used in the heating circuit. The
liquid refrigerant at a high pressure and high tempera-
ture is depressurised (expansion valve). The pressure
and temperature drop and the process begins again.
The heated heating water can be used for the domes-
tic hot water charging or for the building heating. The
temperatures required and use are controlled by the
heat pump controller. Reheating, drying out screed or
increasing the domestic hot water temperature can be
carried out using an electric heating element (acces-
sory), which is activated by the heat pump controller
as and when necessary.
4 Operation and care
NOTE
The unit is operated via the control unit of the
heating and heat pump controller (
Oper-
ating manual of the heating and heat pump
controller).
4.1 Energy-conscious and
environmentally-aware operation
The generally accepted requirements for an energy-
conscious and environmentally-aware operation of a
heating system also apply when using a heat pump.
The most important measures include:
● No unnecessarily high flow temperature
●
No unnecessarily high domestic hot water
temperature (note and follow local regulations)
●
Do not open windows with gap / tilt open
(continuous ventilation), but instead open wide for
a short time (shock ventilation).
●
Make sure that the controller settings are correct
4.2 Care
Wipe down the outside of the unit only using a damp
cloth or cloth with mild cleaning agent (washing-up liq-
uid, neutral cleaning agent). Do not use any harsh,
abrasive, acid or chlorine-based cleaning agents.
