ELECTRONIC HYGROSTAT
EFL 012
The electronic hygrostat is used for controlling heating and cooling equipment, filter fans or signal devices
through the Relay SM 010 or a similar device. The hygrostat registers the surrounding relative humidity and can
switch a signal current via an internal relay with a potential free change-over contact. The LED integrated in the
adjustment knob shows the closed status of the contact 1-2. When relative humidity drops contact 1-2 opens and
the LED turns off. In currentless state (no supply voltage) contact 1-2 opens.
