Connection heat transfer fluid

5.2.1 System solution 1
In system solution 1 the heat pump can produce both heating and hot water with the compressor and the integra-
ted auxiliary 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 auxiliary heater.
The integrated auxiliary heater carries out peak heating charging (antilegionella function) in those operating
modes that permit auxiliary 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
