OPERATION MODES BY SENSORS MALFUNCTION

Outdoor sensor is not connected or has failed
In this case, the controller operates as a P-controller according to room temperature
deviation. If room temperature sensor also has failed or is not connected, the controller
will maintain stand-pipe temperature at the constant value, which is:
- in radiator heating, higher for 25 °C than the set day or night temperature
- in floor heating, higher for 10 °C than the set day or night temperature
Stand-pipe sensor is not connected or has failed
The controller assumes a 120 °C stand-pipe temperature and stops room heating.
Heating can be reactivated only by manual operation mode.
Liquid fuel boiler sensor is not connected or has failed
The controller assumes a 85 °C boiler temperature and activates the burner, if heating
is requires. The boiler temperature can be set manually on a boiler thermostat.
Solid fuel boiler sensor is not connected or has a failure.
The controller assumes a 85 °C solid fuel boiler temperature. Switchover valve turns to
the solid fuel boiler.
Room sensor is not connected or has failed
Room heating operates uninterrupted, according to outdoor temperature.
Return-pipe sensor is not connected or has failed
Room heating operates uninterrupted, without influence of return-pipe temperature.
The sensors of d. h. w. storage tank are not connected or has failed
If one sensor has failed, the controller uses only the other sensor. If both sensors have
a failed, the controller switches off the pump for d. h. w. warming. If the solar collector
temperature is higher than the desired d. h. w. temperature, the solar circulation pump
will be switched on.
Solar collector sensor is not connected or has failed
The solar circulation pump for d. h. w. warming with solar collectors is deactivated.
