Auxiliary heat
A heat pump can produce both heat and hot water. With an external auxiliary heater (oil boiler, electric boiler, district
boiler or similar) heat production is supported but not hot water production. The exchange valve for heating and
hot water is located ahead of the external auxiliary heater, which allows the production of heating and hot water at
the same time. The heat pump control computer also controls an additional shunt located after the external addition.
The SERVICE menu selects AUX. HEATER, EXT.AUX.HEATER. Default setting is:
•
EXT.AUX.HEATER = ON
•
REV.V. HOT WATER = INT
When an oil boiler is used as addition, the after burning time is activated to 60 minutes.
The SERVICE menu selects AUX. HEATER, EXT.AUX.HEATER, TURN OFF DELAY, 60M
