If using underfloor heating, it is imperative that a temperature limit of
50°C is installed and a safety thermostat set to 65°C (cf. NF P 52-
303-1) is fitted, which interrupts the operation of the heating pump in
the circuit concerned should overheating occur.
Connect the safety thermostat wires to the 5 pin connector at the
