Important:
For “Boiler back up” applications, 2 modifications have to be performed on the heat pump:
1) The system control board A1 (and the electric support heater) included in the heat pump must be de-activated. To do
this (with power supply switched off), remove the connectors CX2 and CX3 at the bottom of the electrical plate.
2) The heat pump water temperature control sensor is connected to the input “TW1”of A2 (CCWC2) control board.
Considering that water temperature of the system is controlled according outgoing water temperature, this sensor
connected to “TW1” must be placed on the heat pump water outlet.
To do this, remove this sensor from its housing on the heat pump water inlet (factory mounted) and put it into the
housing provided for this purpose on the water outlet pipe of the heat pump.
Use thermal paste and place correctly the insulating material in order to have a good thermal contact between the
sensor and the pipe.
