Installation manual J5060403 v1.2
If one of the temperature sensors fails, then the controller adjusts itself to the most su-
itable operation mode:
Outdoor temperature sensor isn’t connected or has a malfunction
The controller operates as a P-controller according to room temperature deviation. If the
room sensor is also in error, the controller will maintain constant stand-pipe temperature
which is:
- by radiator heating for 25 °C higher as the set day or night temperature
- by floor heating for 10 °C higher as the set day or night temperature
Stand pipe temperature sensor isn’t connected or has a malfunction
The controller assumes a 120 °C stand-pipe temperature and stops room heating. Heat-
ing can be reactivated only by manual operation mode.
Room temperature sensor or room unit isn’t connected or has a malfunction
Room heating operates normally, with respect of outdoor temperature.
Return pipe temperature sensor isn’t connected or has a malfunction
Room heating operates normally, without limitation of temperature difference between
stand and return pipe.
Boiler temperature sensor isn't connected or has a malfuction
The controller assumes a 85 °C boiler temperature and functioning normally.
