External additional heat
Sun
Function
By connecting a solar heat collector via intermediate heat exchanger to NIBE SPLIT ACVM270, the solar heat can
produce hot water and heating for the house.
If the solar panel does not produce the necessary heat, NIBE SPLIT ACVM270 with the compressor or with internal
immersion heater heats.
The solar panel must have an external charge automatic device (KF) as follows:
Max temperature 65 °C at BT24. P1 stops.
Min temperature 55 °C at T1 for P1 to start.
V1 must limit the temperature to 65 °C.
Accumulators and primary system design are dimensioned by the boiler supplier. Ensure that there is sufficient
volume to prevent overheating.
