DANGER
When handling the electrical installation, make sure that both the module and the Dual Clima
heat pump are disconnected from the mains.
For the electrical connection of the support circulation pump C4 (optional), first two wires must be
connected in parallel with the heat pump circulation pump between terminals C4L and N of the
DUAL CLIMA
heat pump. These cables will be connected to the same terminals (see figure). Then,
these cables must be connected from the terminal strip of the
DUAL CLIMA
heat pump to the
inside of the Fusion Hybrid Gas Condens module on terminals 28 and 29. Finally, the support
circulation pump C4 will be connected to terminals 26 and 27 of the module terminal block (see
"Electrical diagram")
