DHW pump schedule
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.
