DHW pump schedule
Here you can program a schedule for the DHW pump (only for field
supplied domestic hot water pump for secondary return) .
Program a domestic hot water pump schedule to determine when
to turn on and off the pump.
When turned on, the pump runs and makes sure hot water is
instantly available at the tap. To save energy, only turn on the pump
during periods of the day when instant hot water is necessary.
Backup heater
Besides the type of backup heater, the voltage, configuration and
capacity must be set on the user interface.
The capacities for the different steps of the backup heater must be
set for the energy metering and/or power consumption feature to
work properly. When measuring the resistance value of each heater,
you can set the exact heater capacity and this will lead to more
accurate energy data.
Backup heater type
The backup heater is adapted to be connected to most common
European electricity grids. The type of backup heater must be set on
the user interface. For units with a built-in backup heater, the type of
heater can be viewed but not changed.
