Precise Temperature Control Adjustable temperature range of 5 to 40 degrees Celsius enables comfort and ensures the heating system meets specific user preferences. External Sensor Includes a 3meter external sensor for accurate temperature readings away from the heating source, allowing for efficient regulation in different setups. Voltage Compatibility Compatible with 200 to 230V AC at 50/60Hz. This thermostat is intended for underfloor heating systems, making it a reliable choice for diverse installations. Ambient Range Operates effectively in ambient temperatures from 5 to 50 degrees Celsius, delivering consistent performance across a variety of conditions. Use scenarios build or renovated living spaces with underfloor heating: set an exact comfort level within 5 to 40 degrees Celsius to maintain consistent room temperature. Openplan rooms or spaces where the heater is not near the thermostat: place the external sensor up to 3 meters away to measure actual room temperature and regulate more accurately. Environments with variable ambient temperatures (such as basements or unheated zones): rely on reliable operation from 5 to 50 degrees Celsius ambient to maintain stable performance.
