Hygrostat - electronic

Type EFL 012 - electronic hygrostat 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.
