8.5 on/off DHW Production remote contact

The heat pump operation for DHW production is controlled from

a remote contact, e.g. a cylinder thermostat or motorised valve

switch.

The remote ON/OFF DHW contact is enabled by parameter

5119. Refer to Table 8-22. The DHW mode cannot be controlled

automatically by the remote controller.
When DHW is turned ON by the remote contact and the heat pump

is ON it will start operation in DHW (comfort) mode.

DHW ON/OFF remote contact

Contact OPEN = DHW OFF

Contact CLOSE = DHW ON

(Comfort)
