Electronic Hygrostat EFL012

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 into the adjustment knob shows the closed status of the contact 1-2. When the relative humidity drops contact 1-2 opens and the LED turns off. In current less state (no supply voltage) contact 1-2 opens.
