Return water temperature (RWT)
NOTE
A water temperature safety (system return) prevents the heat pump from
operating if the temperature is lower than the heating authorization threshold
with the heat pump (parameter 52). In this case, only the electric backup
heating is authorized to raise the water temperature and allow the heat pump
to operate, at any external temperature. If the backup heating is not
installed (P09 = 0) this protection is not active. For this reason, the heat
pump stops and the display will show the writing: RWT < P52
