3.3 Operating principle
3.3.1. General
The outside module produces heat or cold (in reversible versions) and
transmits it to the heating circuit via the refrigerant in the plate
exchanger.
The outside module is capable of operating at outside temperatures
down to -20°C (-15°C in the case of a 6MR or 8MR heat pump).
The DIEMATIC iSystem control panel is used to programme and
regulate the heat pump according to the outside temperature.
By activating the pumps and, where necessary, the mixer valve, the
regulator handles the regulation of the heating.
Connection of a CDR4 simplified remote control or a CDI4 interactive
remote control enables the auto-adaptivity of the gradient and the
parallel offset of the heating curve.
The antifreeze function on the installation is active whatever the
operating mode. It is triggered as soon as the outdoor temperature
reaches the limiting value preset to +3°C.
The installation of a buffer tank is not necessary if the volume of water
in the circuit is higher than or equal to 3 litres/kW: Therefore, for a
heat pump with an output of less than 11 kW, with a water volume of
less than 33 litres, the installation of a buffer tank is necessary.
