Termofol TF-H3: manual control for electric underfloor heating
The TF-H3 is a flush-mounted thermostat with a rotary dial for electric underfloor heating. Set the temperature manually, without a weekly programme or app. The Termofol 2025 catalogue states that a floor temperature sensor is included. Simple operation does not establish a guaranteed lifespan or lower fault rate than digital models.
Data from the Termofol 2025 catalogue
The catalogue lists a maximum load of 16 A, a 5–35 °C setting range, ±1 °C control tolerance and an NTC B3950 10K sensor. Overall dimensions are 84 × 84 mm, or 57 × 57 mm without the frame. The controller consumes less than 2 W. The catalogue gives IP31 for this version. When replacing a unit, check that the supplied version matches these details.
Compatibility and correct connection
Have the installer check the 230 V AC, 50/60 Hz connection against the rating plate and model manual. Electrical load, sensor type, floor construction and the floor covering’s temperature limit must all be compatible. Staying below 16 A alone does not establish compatibility with every system. A setting range up to 35 °C does not mean your floor covering permits that temperature.
Position the floor sensor and thermostat according to both products’ instructions. For a bathroom, have moisture exposure and the complete installation assessed; IP31 does not permit placement anywhere. Follow temperature-limiting, cleaning and inspection guidance. Do not use the product to replace any separately required protective device.
Advice and ordering
We advise private and business end users, installers and wholesalers. Send the underfloor heating type, power and details of any existing sensor. We confirm a compatible combination, available version, scope of supply and warranty terms. For scheduling or remote control, we can compare a controller that actually supports those functions.
