Controls both temperature and humidity
Contact type:
The ETF 012 senses the ambient temperature and
relative air humidity. 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 above the set point. The integrated
LED in each adjustment knob is lit indicating the
active function.
