Function description
Start the heat pump via the external temperature
sensor (B9). This works directly in the heating
circulation.
Depending upon the ambient temperature, the heat
pump is switched on and off via the return flow
temperature (B71). The machine has a starting delay in
order to prevent wobbling.
The integrated electric heating insert (K25) can be
used as emergency heating.
The condenser pump (Q9) is in operation during the
entire heating period.

Function description
Start the heat pump via the external temperature sensor
(B9). This works directly in the heating circulation. A buffer
storage is integrated in the return flow.
Depending upon the ambient temperature, the heat
pump is switched on and off via the return flow
temperature (B71). The machine has a starting delay in
order to prevent wobbling.
The integrated electric heating insert (K25) can be used
as emergency heating.
The condenser pump (Q9) is in operation during the entire
heating period.
The size of the built-in expansion vessel (EV) must be
controlled and depending upon the water content must
be supplemented with an external vessel.

Function description
Start the heat pump via the external temperature
sensor (B9). This works on the buffer storage.
Depending upon the ambient temperature, the heat
pump is switched on and off via the temperature
sensor (B4) or (B71). The machine has a starting delay
in order to prevent wobbling.
The integrated electric heating insert (K25) can be used
as emergency heating. The pump (Q2) is in operation
during the entire heating period.
The size of the built-in expansion vessel (EV) must be
controlled and depending upon the water content must
be supplemented with an external vessel.
The discharge circuit control is controlled with the
optional heating circuit mixer (Y1) via the flow
temperature sensor (B1) depending upon the outside
temperature. The buffer storage can be charged at
reduced rate.
