Return temp.
(S4)
Push and hold the shift button to see:
- the calculated flow temperature
- the desired return temperature limitation.
This display can also show the actual and desired flow and return
temperatures for circuit II.
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.

Controller mode
Choose the unit you want to control. The selected
unit symbol will blink.
Controlled units are switched OFF or ON when
the relevant button is pushed.
The motorized actuator (gear motor)
closes or opens the controlled unit as long as
the relevant button is pushed. If pushed for more
than 3 seconds, the actuator continues to close or
open the valve.
The thermo actuator
activates the valve as long as the
button is
pushed. If pushed for more than 3 seconds, the
actuator continues to open the valve.
Check the activation direction of the actuator either by
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.
