Description
Sets the temperature difference between the collector and cylinder
temperature at which the solar pump should be switched on
Sets the temperature difference between the collector and cylinder
temperature at which the solar pump should be switched off
Sets the maximum cylinder temperature that is permissible when
solar gain is available
Sets the maximum permissible temperature on the collector
Choice of additional heat source
Off: (no add. heat source)
Bivalent: 2nd heat generator, e.g. oil, gas or wood boiler
Sol: Thermal solar energy system
Limit temperature for the 2nd heat generator. The heat pump is
blocked below this temperature
Activates the electric heater (parallel to the heat pump) in photovol-
taic mode
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.
