2 TECHNICAL DATASHEET Toll free: 1-888-783-4611 (US & Canada only) www.stegousa.com ELECTRONIC HYGROSTAT EFL 012 > Large setting range > Optical function display > Compact design > Signal application > Small hysteresis 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. TECHNICAL DATA Switching difference 5 %RH ( 3 %RH tolerance) at +77 F (+25 C) and 50 %RH Reaction time approx. 5 sec.
