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
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 changeover 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
Cooling is integrated in type K units. Type H units can
be retrofitted with the "Cooling package" accessories.
The following options are possible for units with
cooling function ( operating manual of the heating
and heat pump controller):
● Passive cooling (without compressor)
● Control of the cooling function via the heating and
heat pump controller
● Automatic switching between heating and cooling
mode
Network connection on the control
The control can be connected to a computer or
network via a network cable. The heating and heat
pump controller can then be controlled from the
computer or from the network.

Operation and care

NOTE
The unit is operated via the control of
the heating and heat pump controller
( operating manual of the heating and heat
pump controller).
4.1 Energy and environmentally
aware operation
The generally accepted requirements for energy-
aware and environmentally-aware operation of a
heating system also apply to use of a brine/water 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 (purge ventilation)

4.2 Maintenance

Wipe down the outside of the unit only using a damp
cloth or cloth with mild cleaning product (washing-up
liquid, neutral cleaning product). Do not use any harsh,
abrasive, acid or chlorine-based cleaning products.
