INFORMATION
Solar panels. If solar panels are used, set the electricity
price value very low to promote the use of the heat pump.
Space heating control
The basic required settings in order to configure the space heating 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 10°C.
See the user reference guide and/or operation manual for more
details about this function.

INFORMATION
In order to optimise comfort as well as running costs, it is
recommended to choose weather-dependent setpoint
operation. Set the settings carefully; they have significant
of
influence on heat pump as well as boiler operation. Too
high leaving water temperature can result in constant boiler
operation.
NOTICE
In case of third-party gas boiler:
If you use weather-dependent operation, make sure to set
the values for the weather-dependent curves twice for
correct operation:
▪ Once on the user interface of the outdoor unit
▪ Once on the third-party gas boiler
