Set the speed at which the heating medium pump is to
operate in the present operating mode. Select "auto" if
the speed of the heating medium pump is to be regu-
lated automatically (factory setting) for optimal operation.
If "auto" is activated for heating operation you can also
make the setting "max. allowed speed" which restricts
the heating medium pump and does not allow it to run
at a higher speed than the set value.
For manual operation of the heating medium pump,
deactivate "auto" for the current operating mode and set
the value to between 0 and 100% (the previously set
value for "max. allowed speed" no longer applies).
"heating" means heating operating mode for the heating
medium pump.
"speed in wait mode" means heating or cooling operating
mode for the heating medium pump, but when the heat
pump requires neither compressor operation nor electric
additional heat and slows down.
"hot water" means hot water operating mode for the
heating medium pump.
"pool" (accessory required) means pool heating operating
mode for the heating medium pump.
"cooling" (accessory required) means operating mode
cooling for the heating medium pump.
If there are accessories for cooling present or if the heat
pump has a built-in function for cooling you can also set
the heating medium pump speed during active respect-
ively cooling operating modes (the heating medium
pump then runs in manual operation).
