R-PAC Option: Filtration pump controlled by the heat pump
This system helps the heat pump to force the water filtration pump to work if the
water temperature is not reached.
In order to set up this option, it is necessary to connect heat pump terminals “9”
and “10” to the filtration pump contactor on the following way:
- Identify on the power supply of the filtration pump, the phase and neutral
terminals
- Identify on the contactor of the filtration pump, the phase and neutral
terminals (“A1” and “A2”)
Once these elements are identified:
- Connect together the two neutral terminals: from the power supply and from
contactor of the water filtration pump (Wire A on the picture)
- Connect the phase from the water filtration pump power supply to terminal
“10” of the heat pump. (Wire B on the picture)
- Connect the phase from water filtration pump control to terminal “9” of the
heat pump. (Wire C on the picture)
