16.9 Menu 9.7.6 - Setting the valve mode

Electrothermal valves with the switching states "normally closed
(NC)" or "normally open (NO)" are often used for heating control.
You can set the respective valve mode in menu 9.7.6 to adapt to
the control valve used in each case:
[ NC ] Valve mode normally closed
The control valve remains closed in an isolated,
de-energised state.
[ NO ] Valve mode normally open
The control valve remains open in an isolated,
de-energised state.

The set valve mode also applies to DuoFern
actuators connected via radio.
