Section 8: Operation

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 8-8. 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

! NOTE !

In order to use DHW function, it is necessary to set 

parameter 3101=1 and parameter 5119=1.

! NOTE !

Turn ON both remote controller using ON/OFF button, and 

DHW ON/OFF remote contact to start heat pump for DHW.

! NOTE !

This volt free remote contact is provided by the Grant EP002 

Interface relay box. Refer to Sections 6.8 and 6.10.
