Precise temperature control: adjustable temperature range 5 to 40 degrees Celsius lets you tailor heating to your environment and comfort level. External sensor for accuracy: a 3meter external sensor keeps the thermostat away from heat sources, improving readings, performance, and reliability. Voltage compatibility: operates on 200 to 230V AC at 50/60Hz, suitable for standard residential wiring and a variety of heating setups including underfloor systems. Robust ambient range: functional in ambient temperatures from 5 to 50 degrees Celsius for consistent performance across different conditions. Use cases: Underfloor heating systems in homes or apartments powered by 200–230V mains. Rooms where the thermostat should be placed away from heat sources; the external sensor provides accurate readings in living rooms, kitchens, or offices. Spaces with wide temperature swings such as garages, basements, sunrooms, or workshops requiring reliable heating control.
