AUTOMATIC TEMPERATURE SENSOR DETECTION
After the controller setup or change of the hydraulic scheme, the controller automatically
detects all the connected sensors. Sensor that are not connected are marked with - - -. If
later the sensor is removed or has a failure, then the controller shows an error
circuit) or
(open contact) for the affected sensor.
SENSOR AF ISN'T CONNECTED OR HAS A FAILURE
The controller operates as a P-controller according to room temperature deviation. If the
room sensor isn't connected, the controller will maintain stand-pipe temperature set on the
day temperature button.

temperature
Radiator heating
Floor heating
SENSOR VF ISN'T CONNECTED OR HAS A FAILURE
The controller assumes a 120 °C stand-pipe temperature and stops room heating. Heat-
ing can be reactivated only by manual operation mode.
SENSOR KF ISN'T CONNECTED OR HAS A FAILURE
The controller assumes a 85 °C boiler temperature and activates the burner. The boiler
temperature can be set manually on a boiler controller.
SENSOR KF2 ISN'T CONNECTED OR HAS A FAILURE
The controller assumes a 85 °C solid fuel boiler temperature. Switchover valve turns to
the solid fuel boiler.
SENSOR RF ISN'T CONNECTED OR HAS A FAILURE
Room heating operates uninterrupted, according to outdoor temperature.
SENSOR RLF ISN'T CONNECTED OR HAS A FAILURE
Room heating operates uninterrupted, without influence of return-pipe temperature.
SENSORS BF1 OR BF2 AREN'T CONNECTED OR HAVE A FAILURE
If BF1 has a failure, the controller uses only BF2. If BF2 has a failure, the controller uses
only BF1.
If both sensors have a failure, the controller switches off BLP and KTP pump.
SENSOR KTF ISN'T CONNECTED OR HAS A FAILURE
The circulation pump KTP for d. h. w. warming with solar collectors is deactivated.
In certain circumstances the controller response can differ.
