XVI.1. Fresh air filter pressure switch DEP FS
XVI.1.a.
The condition of the supply air filters (fresh air) is continuously monitored by an air
pressure switch which informs the controller of the pressure drop. If the pressure
drop of the filters exceeds the pressure switch setting, the controller informs the
user by means of a warning.

The filter pressure switch is of the NO type (normally open). The contact is open at rest and closes when the filter pressure drop
(differential pressure) is higher than the setting (200 Pa at the factory).
The pressure switch must be connected between terminals (1) and (3) according to the electrical wiring diagram.
