TERMOFOL TF-H3-BLACK Manual Thermostat – Reliable Temperature Control with a Rotary Dial The TERMOFOL TF-H3-BLACK is a robust and easy-to-use manual thermostat for electric underfloor heating. This model is ideal for users who prefer classic operation, direct control, and maximum reliability. The clear rotary dial allows you to quickly and accurately set the desired temperature without complicated menus or settings. Thanks to the built-in safety features and the accurate floor temperature sensor, the TF-H3-BLACK offers stable and safe operation in any room. Smart Features for Comfort and Safety Precise Temperature Control The mechanical rotary dial allows you to easily set a temperature between 5°C and 35°C, with a control deviation of only ±1°C. This maintains constant comfort and prevents unnecessary energy consumption. Built-in Floor Sensor The thermostat comes with an NTC B3950 10K floor temperature sensor, which continuously measures the temperature and ensures optimal operation of the heating system. Antifreeze function: The special frost protection mode automatically maintains a low temperature to prevent pipes and floors from freezing. This mode is easily activated using the snowflake symbol on the dial. Mechanical temperature limit: The integrated red and blue adjustment pins allow you to mechanically limit the minimum and maximum temperatures. This increases safety and prevents unwanted adjustments. Automatic temperature reduction: The TF-H3 features a switch-back function that automatically lowers the temperature when full heating is not required. This reduction is set to 6°C by default, adjustable between 2 and 8°C, contributing to energy savings. LED status indication The integrated LEDs show the thermostat status at a glance: 🔴 Red – heating active 🔵 Blue – anti-freeze mode 🟢 Green – standby 🟡 Yellow – temperature reduction active 🔴 (flashing) – sensor fault Technical specifications Feature Specification Power supply 120–240 V AC / 50–60 Hz Temperature range 5 °C – 35 °C Control deviation ±1 °C Maximum load 16 A / 3600 W Recommended load Max. 90% of 16 A Temperature sensor NTC B3950 10K (floor sensor) Protection class IP31 Overall dimensions 84 × 84 mm Dimensions without frame 57 × 57 mm Mounting Flush-mounted Compatibility Suitable for 56 × 56 mm frames (including Schneider Exxact) Easy installation and operation The TF-H3-BLACK is mounted in a standard flush-mounted box and connected via a clear terminal block for power supply, heating cable and floor sensor. Operation is intuitive: turn the knob to instantly select the desired temperature. Conclusion The TERMOFOL TF-H3-BLACK is an excellent choice for those looking for a reliable, manual thermostat without unnecessary complexity. With its precise control, anti-frost function and mechanical protection, it offers comfort, safety and energy efficiency for electric underfloor heating.
