Thermostat TF-H3

TERMOFOL TF-H3 Thermostat – manual control of underfloor heating

TERMOFOL TF-H3 is a manual thermostat designed for controlling electric underfloor heating. The classic knob allows quick setting of the required temperature in the range of 5–35°C, without the need for programming schedules or configuring applications. The thermostat controls the temperature using an external NTC B3950 10K floor sensor.

TF-H3 is particularly suitable where simple and direct heating control is required. The colored LED indicates the current state of the device – heating, standby, anti-freeze mode, reduced temperature, or sensor error. After power loss and reconnection, the thermostat retains the temperature set using the knob.

An additional advantage is the ability to mechanically limit the available temperature range, allowing you to set the minimum and maximum values that can be set by the user. The thermostat also offers a Setback function, allowing the temperature to be reduced by a selected value from 2 to 8°C.

Internal Use

Thermostats TERMOFOL are designed for controlling electric heating systems inside buildings. They primarily cooperate with heating films and mats, allowing precise control of underfloor heating temperature, and suitable models also with wall and ceiling systems.

They perform well in houses, apartments, offices, and other utility rooms, allowing the heating operation to be adapted to the user's needs. Depending on the model, features such as schedule programming and remote control via WiFi are available.
