Nameplates
One nameplate is attached to the heat pump module in
the rear facade cut-out at the factory.
Two further nameplates are included in the delivery.
►
Stick one nameplate on the outside of the unit on
the lower facade of the switch box side.
►
Glue one nameplate into the logbook fpr heat
pumps.
The nameplates contain the following information at
the very top:
●
Model, item number
●
Serial number
The nameplates also contain an overview of the most
important technical data.
3.3 Accessories
The following accessories are available for the unit via
the manufacturer’s local partner:
●
Connection set, hydraulic
●
Connection set, electrical
●
Domestic hot water tank
●
Buffer tank
●
Room thermostat for switching the cooling function
●
Dew point monitor for protecting a system with
cooling function at low flow temperatures

3.4 Function
Liquid refrigerant is evaporated (evaporator). The en-
ergy for this process is ambient heat coming from the
outside air. The gaseous refrigerant is compressed
(compressor), which increases the pressure and thus
also the temperature. The gaseous refrigerant with
high temperature is liquefied (condenser).
Here, the high temperature is transferred to the heat-
ing water and used in the heating circuit. The liquid re-
frigerant with high pressure and high temperature is
expanded (expansion valve). The pressure and tem-
perature drop and the process restarts.
The heated heating water can be used for the domestic
hot water or for heating the building. The temperatures
required and the use are controlled by the heat pump
controller. Any required reheating, support in screed
drying or increase in the domestic hot water temper-
ature can be carried out using an electric heating ele-
ment, which is activated by the heat pump controller
as required.
The integrated vibration decoupling for the hydraulic
system prevents structure-borne sound and vibrations
from being transferred to the fixed pipes and thus to
the building.
Cooling
Cooling is integrated in the units. The following op-
tions are possible for the cooling function (
operat-
ing manual of the heating and heat pump controller):
●
Active cooling
Cooling in combination with hydraulic module or
hydraulic station up to a minimum flow temperature
of 18 °C. In combination with wall-mounted control-
ler up to a minimum flow temperature of 7 °C
●
Cooling below 18 °C is only possible in the case
of hydraulic integration with separation buffer tank
●
The cooling function is controlled via the heating
and heat pump controller
●
Switching over between heating and cooling
mode
4 Operation and care
NOTE
The unit is operated via the control panel of
the heating and heat pump controller (
op-
erating manual of the heating and heat pump
controller).
4.1 Energy and environmentally
aware operation
The generally applicable requirements for energy and
environmentally aware operation of a heating system
also apply to the use of a heat pump. The most impor-
tant measures include:
●
No unnecessarily high flow temperature
●
No unnecessarily high domestic hot water tem-
perature (observe local regulations)
●
Do not open windows with gap/in tilt position (con-
tinuous ventilation), but instead open wide for a
short time (shock ventilation)
●
Always ensure that the controller setting is correct
