Pricing available on request EFL 012 Panel Electronic Hygrostat: The electronic hygrostat measures the relative humidity in the area and has an internal relay with a potential-free change-over contact that allows it to switch a signal current. Direct control of signal-processing equipment is possible with the EFL 012. To regulate heating and cooling equipment, filter fans, and signal devices, the switch module SM 010 or a comparable device is required. The LED embedded in the adjustment knob indicates that contact 1-2 is closed. When relative humidity decreases, contact 1-2 opens and the LED turns off. When there is no supply voltage and no current, contact 1-2 opens.
