CAUTION
The solar panels MUST be installed higher than the indoor unit. A downward slope
with minimum gradient of the solar piping MUST be guaranteed. This is to allow the
solar system to completely drain and thereby to avoid frost damages.
Configuration
Via the user interface:
▪ Select, whether all other heat sources are stopped, when solar energy is
provided.
▪ Select tank temperature, above which all other heat sources are stopped, when
solar energy is provided.
