8.2 Control Board

8.3 Heating Function

Set switch (1) to position On (I) to put heat pump into operation.
The heating mode can be preselected by placing switch (3) to the
Heating ( ) position. The desired return temperature can be set
using selector dial (4), the relevant call for heat is controlled by
the potentiometer and lies within a range of min. 10 °C and max.
55 °C. If the preset temperature is reached, the heat pump
switches off. Once the return temperature drops below the preset
temperature by 4 Kelvin, the heat pump switches back on. In the
event that the preset return temperature cannot be reached, the
output for the back-up heater cuts in after approx. 1 hour. The
heat pump cannot be restarted until a minimum time delay of
5 minutes has elapsed. At a supply temperature of approx. 60 °C
or if the air temperature is too low, the heat pump switches off.

8.4 Domestic Hot Water Function

This heat pump can also be used for heating domestic water.
The call for domestic water heating is controlled by terminal
"X2-7" by means of a thermostat to be provided by the client. This
thermostat connects phase (L) to terminal "X2-7" and controls a
reversing valve which is part of the hot water switch group "N13".
A suitable thermostat is available as an accessory.
The call for domestic water heating may also occur if no call for
space heating exists. On a call for heat, the control unit switches
off the heating circulating pump and the setpoint is set to maxi-
mum.
When the preparation of domestic hot water is concluded, the
heat pump controls switch back into normal operation.

Cleaning / Care

9.1 Care

To protect the paint finish, avoid placing objects against or on the
unit. The external parts of the heat pump can be wiped with a
damp cloth and commercially available cleaning agents.
ATTENTION!
Do not use any cleaning agents containing sand, soda, acid or chloride as
these may damage the surface.
To prevent malfunctions due to dirt deposits in the plate heat ex-
changer of the heat pump, care must be taken that the heat ex-
changer cannot become contaminated in the heating installation.
In the event that operating malfunctions due to contamination
occur nevertheless, the system should be cleaned as described
below. (Caution: The fins of the finned heat exchanger have
sharp edges -> risk of cutting injuries!)
