INFORMATION
In order to optimise comfort as well as running costs, it is
recommended to choose weather­dependent setpoint
operation. Set the settings carefully; they have significant
influence on heat pump as well as boiler operation. Too
high leaving water temperature can result in constant boiler
operation.

Description
Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature. This
allows better matching of the
heat pump capacity to actual
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.
