The electronic hygrotherm ETF 012, part number 01231.9-01, monitors temperature and humidity to prevent condensation by switching heating or fans. It includes an external sensor with a 2 m cable and operates on AC 100 V to 240 V. The device features a plastic housing compliant with UL94 V-0, LED status display, and operates between -40 °C and 60 °C. It mounts on a 35 mm DIN rail, measures 77 mm high, 60 mm wide, and 43 mm deep, and weighs 200 g. Switching capacity is rated for AC 240 V at 10 A resistive and 1.6 A inductive, with a relay service life of over 30,000 cycles under UL standards.
