In circuit
III, the motorized control valve no. 2 actually
symbolizes the motorized control valve no. 3.
In circuit II, controlled units are not shown. Instead the position of
the motorized control valve is displayed.
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.

In circuit II, controlled units are not shown. Instead the position
of the motorized control valve is displayed. The motorized
control valve of circuit II is voltage controlled (0 - 10 V). It can be
controlled manually by pressing the shift button and the plus /
minus buttons.
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.
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 all circuits.
During manual operation, all control functions are deactivated.
