5.3 Solar kit wiring
The solar pump station will have an auxiliary contact that closes when the contact for the
pump of the solar pump station is operated.
This contact will provide 220-240V~ 50Hz to the input of the indoor unit, and prevent sanitary
water heating by the heat pump and/or electric heater during solar heating.
For wiring examples refer to the following drawings.
If the solar energy pump cannot set the sanitary hot water tank temperature below 60℃, then use
the connecting method as shown below.

Caution:
If the pump station has a speed controlled pump, make sure to disable this function so that the
indoor PCB receives 220-240V~ 50Hz at all times.
