The DEVIreg™ 316 is a versatile electronic thermostat designed for DIN rail installation in electric cabinets. It excels in frost protection for roofs, gutters, and downpipes, and also manages room and floor temperatures, ventilation, cooling, snow melting, and pipe tracing. Its key feature is the temperature range mode, allowing heating within set upper and lower limits, ideal for frost protection with an external air sensor. The device includes two buttons for hysteresis and economy period adjustments, requiring an external timer. With relay contacts NO and NC, it supports heating and cooling systems and can handle control voltages up to 250V. The sensor circuit is safely isolated from high voltage components, ensuring secure operation.
