* If sensor S3 is not connected, the sensor S5 values will be displayed
Push and hold the shift button to see:
- the calculated flow temperature
- the desired return temperature limitations.
The activity of the motorized control valve is shown as arrows
below the valve symbol. When the circulation pump is
operating, it is indicated as ON below the pump symbol.
If a sensor is not mounted or is disconnected, the display will
indicate it as "- -".
If the sensor is short-circuited, the display will indicate
it as "- - -".
If you are in doubt, remove the controller and check the
ohmic value between the relevant terminals.

The thermo actuator
activates
pushed. If pushed for more than 3 seconds, the

looking at it or by feeling whether the temperature of the
actual pipe changes as expected.
This operation applies to both circuits, if available.
During manual operation, all control functions are deactivated.
