Regulation and control devices
The domestic hot water heat pump is equipped with the following
regulation and control components:
The temperature controller for the heating element regulates the
hot water temperature when the water is being heated by the
heating element. The factory default setting is 65 °C.
Temperature control in the water circuit and the regulation for
compressor operation is carried out by the temperature
controller. This regulates the water temperature on the basis of
the setpoint. The desired temperature can be set by means of a
rotary knob on the control panel.
The air temperature thermostat is mounted on the control room
panel. Whenever the set switching value (8 °C) is undershot,
domestic hot water heating is automatically switched from heat
pump operation to heating element operation.
The thermometer sensor measures the hot water temperature in
the upper part of the domestic hot water cylinder.
In the case of domestic hot water heat pumps equipped with an
additional internal heat exchanger, a relay with a floating contact
automatically switches on a second heat generator according to
need.

Set-up
The domestic hot water heat pump must be installed in a frost-
free room. The installation location should fulfil the following
prerequisites:
 Have a room temperature between 8 °C and 35 °C
(for heat pump operation)
 Be thermally well insulated from the neighbouring rooms
(recommended)
 Have a drainage available for the condensate produced
 Have an environment that is not excessively dusty
 Have a load-bearing floor (approx. 500 kg)
To ensure smooth operation and facilitate repair and
maintenance work, there should be minimum clearances of 0.6
m on all sides of the device as well as a minimum room height of
approx. 2.50 m when implementing a “free venting” installation
setup (without air ducts/hoses or bends).
At least one air circuit bend (90° NW 160) must be installed on
the blow-out side for effective operation in rooms with lower
ceilings.
