5.2.1 System solution 1
Description
In system solution 1 the heat pump can produce both heating and hot water with the compressor and the integrated immersion heater.
Production of heating and hot water cannot occur at the same time because the exchange valve for heating/hot water is positioned
after the immersion heater.
The integrated immersion heater carries out peak heating charging (antilegionella function) in those operating modes that permit auxili-
ary heat.
For system solution 1, select the factory setting in menu SERVICE\AUX. HEATER\EXTERNAL ADDITION:
▪ EXTERNAL AUX. HEATER = 0 (Off)
▪ REV.V. HOT WATER = INT
