Quick wizard: Capacities (energy
metering)
The capacities of all electrical heaters must be set for the energy
metering and/or power consumption control 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.

Space heating/cooling control
The basic required settings in order to configure the space heating/
cooling of your system are described in this chapter. The weather-
dependent installer settings define the parameters for the weather-
dependent operation of the unit. When weather-dependent operation
is active, the water temperature is determined automatically
depending on the outdoor temperature. Low outdoor temperatures
will result in warmer water and vice versa. During weather-
dependent operation, the user has the possibility to shift up or down
the target water temperature by a maximum of 5°C.
See the user reference guide and/or operation manual for more
details about this function.
