Manual Underfloor Heating Thermostat 220V 16A, Electric Floor Heating Controller with Mechanical Rotary Knob and 3m Floor Sensor Probe – Flush Mount XUEMEI manual room thermostat provides automatic on/off control for electric underfloor heating systems and other electric heating applications. Temperature control range: 5°C to 40°C. Maximum load: 16A resistive. CE certified for safety and reliable performance. Simply press the button to turn on and adjust the desired temperature using the rotary knob. The built-in air sensor monitors room temperature and automatically stops heating when the set temperature is reached. Equipped with an internal air sensor and a 3-meter NTC floor sensor probe. The internal sensor measures ambient room temperature, while the external floor probe prevents excessive floor surface temperature by limiting it to a maximum of 50°C. LED power indicator shows when the heating system is active. A lit LED indicates that the thermostat is calling for heat. Specifications: Power supply: 230V AC 50/60Hz; Power consumption: 5W; Temperature limit range: 25°C to 55°C; Protection rating: IP20. Package includes: 1 x Thermostat, 1 x 3m floor sensor probe, 2 x mounting screws, 1 x user manual in English. Safe, energy-efficient, and high-performance design. Wall-mounted installation for indoor use. Ensure the thermostat is installed on an interior wall with free air circulation, away from direct sunlight, drafts, or external heat sources to ensure accurate temperature readings. Simple operation: 1. Push button: "I" = On, "O" = Off 2. Temperature setting: Turn the rotary knob to select desired temperature 3. LED indicator: Lights up during heating cycle Suitable for electric underfloor heating systems and other resistive heating loads. Installation note: Mount the thermostat at a height of 1.2m to 1.6m from the floor, on an interior wall with no obstructions to airflow. Avoid locations near windows, doors, or other heat sources.
