14.5 SOLAR THERMAL ENERGY The heating battery of the hot water tank
has a surface area of 0.8m² and allows
for the connection of a solar system and
therefore of a further regenerative energy
source. The collector field should be dimen-
sioned appropriately to ensure perfect
operation. The solar control is already inte-
grated into the heat pump combi unit. The
collector sensor and the solar pump are
connected directly to the main board. The
pump is controlled via a 0-10 V signal.
In the [settings] > [additional functions] the
solar circuit must be additionally activated.
