Suitability of this product for its intended use and any associated risks must be determined by the end customer/buyer in its final application. The ETF 012 senses the ambient temperature and relative 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 i lit when indicating the active function. The external sensor can be positioned freely anywhere in the enclosure for precise measurements.
