XUEMEI flush mount, this manual room thermostat is designed to provide automatic on/off control for electric underfloor heating systems and other electrical heating elements. Temperature control range: 540C. Output: Max 16A. CE certified, safe and easy to use. Press the push button to turn on and set the desired room temperature using the rotary knob. When the built-in air sensor detects that the room temperature reaches the preset level, the thermostat automatically pauses the heating. Equipped with a built-in sensor and a 3m NTC external floor probe. The built-in sensor measures room temperature, while the external probe provides floor temperature protection to prevent the floor surface from exceeding 50C. LED indicator shows when the heating system is active. A lit LED indicates that the system is currently heating. Specifications: Power supply: AC230V 50/60Hz; Power consumption: 5W; Floor sensor temperature limit range: 2555C; Protection rating: IP20. Package includes: 1 x Thermostat, 1 x 3m floor sensor, 2 x Mounting screws, 1 x English user manual. Safe, energy-saving, and high performance. Wall-mounted design for indoor installation with free air circulation around the unit. Avoid placement near heat sources (e.g., direct sunlight), drafts from doors or windows, or exterior walls that may affect temperature readings. Simple operation: 1. Push button: "I" for on, "O" for off. 2. Temperature setting: Turn the knob to adjust the desired temperature. 3. LED indicator: Lights up during heating cycles. Suitable for electric underfloor heating systems and other resistive heating loads. Ensure proper installation on an interior wall for accurate temperature sensing and optimal performance.
