temperature at which the solar pump should be switched on
Switch-off difference
2 K ...
4 K
... 6 K
Sets the temperature difference between the collector and cylinder
temperature at which the solar pump should be switched off
Max. cylinder temp.
60 °C ... 65 °C ... 85 °C
Sets the maximum cylinder temperature that is permissible when
solar gain is available
Max. collector temp.

Entry of the domestic hot water setpoint, which is active when pho-
tovoltaic inlet is connected. The increased setpoint is also active if
the air intake temperature does not allow the heat pump to operate.
In this case, the request is processed with the electric heating ele-
ment or, where present, the 2nd heat generator.
