STEGO Electronic Hygrotherm ETF 012 01230.9-00

The ETF 012 senses the ambient temperature and relative air humidity in an enclosure. Depending on which contact combination is chosen, it then turns on or off a connected device if either the temperature is below or the humidity is above the set point. The integrated LED in each adjustment knob is lit when indicating the active function. Technical Data Switching difference (temperature) 2 K (±1 K tolerance) at +25 °C (+77 °F), 50 %RH Switching difference (humidity) 4 %RH (±1 % tolerance) at +25 °C (+77 °F), 50 %RH Reaction time (humidity) approx. 5 sec.
