if the control is mounted on the wall
● Room thermostat for switching the cooling
function
● Dew point monitor for protecting a system with
cooling function at low flow temperatures

3.3 Function
Liquid refrigerant is evaporated (evaporator), the
energy for this process is environmental heat and
comes from the “ground” heat source (collector,
borehole heat exchanger or groundwater via
intermediate exchanger). The gaseous refrigerant is
compressed (compressor), this causes the pressure
to rise and therefore the temperature too. The
gaseous refrigerant with high temperature is liquefied
(condenser).
Here the high temperature is discharged to the heating
water and is used in the heating circuit. The liquid
refrigerant with high pressure and high temperature
is expanded (expansion valve). The pressure and
temperature drop and the process begins again.
Due to the integrated switching valve and the integrated
energy efficiency circulation pump the heated heating
water can be used for charging the domestic hot
water or for heating the building. 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 the integrated electric heating element, which
is activated by the heat pump controller as and when
necessary.
An integrated overflow valve ensures that the heat
pump does not switch to high-pressure fault if all
heating circuits are closed. The integrated vibration
isolators for the heating circuit and heat source
prevent structure-borne sound and vibrations from
being transferred onto the fixed pipes and therefore
into the building.
Cooling
The cooling function has the following options
(

● Passive cooling (without compressor)
● Control of the cooling function via the heating and
heat pump controller
● Automatic switching between heating and cooling
