ETF 012 Electronic Hygrotherm

Efficient temperature & humidity control
Wide adjustment ranges
High switching capacity
Optical function displays (LED)
DIN rail mountable

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 is above the set point. The integrated LED in each adjustment knob is lit when indicating the active function.
