Thermostats

First, check the thermostat's user manual. The cause may be an active child lock, which prevents settings from being changed using the buttons or the touch panel.

An active lock is usually indicated by a padlock or key symbol shown on the display. The way to disable it depends on the thermostat model and is described in the device's user manual.

A flashing heating symbol usually means that the floor overheat protection has activated. With a correctly performed installation, this is not a sign of a fault.

The thermostat switches off the heating when the temperature read by the floor sensor reaches the set maximum value. Once the floor has cooled and the temperature drops below this value, the heating will be automatically switched back on.

Example:

If the maximum floor temperature has been set to 28°C, the thermostat will switch off the heating once this temperature is reached. When the floor temperature drops, e.g. to 27°C, the thermostat will switch the heating back on.

Most thermostats are wired in a similar way: the supply cables are connected to the power terminals, and the cables leading to the heating installation are connected to the load output, usually marked L1 and N1.

The exception is the TF-H7 model, which is equipped with a potential-free (dry) contact.

A potential-free contact works like a switch — it does not supply its own voltage. The thermostat simply closes or opens the control circuit. This solution allows control of the phase conductor supplying the heating film, or of an external actuating device, e.g. a contactor.

When a potential-free contact is used, the neutral conductor N must be routed directly to the load, bypassing the thermostat.

The maximum power of a heating installation that can be connected directly to the thermostat is 3000 W for all thermostat models.

If the total installation power exceeds 3000 W, it must not be connected directly to the thermostat. A contactor sized for the load should be used, or the installation should be divided into smaller, independently controlled heating zones with a larger number of thermostats.

A floor sensor is included with every thermostat and is supplied in its packaging.

If the sensor is damaged, a suitable replacement can be purchased through our listings.

Most thermostats are designed for installation in a standard flush-mounted electrical box.

The exception is the TF-H2 model, which is a surface-mounted thermostat and does not require installation in a flush-mounted box.

Before adding a device to the app, switch it into Wi-Fi pairing mode.

The way to start pairing mode may vary depending on the device model. Follow the user manual — the device usually indicates active pairing mode with a flashing Wi-Fi icon or an appropriate message on the display.

When adding a device, it is recommended to select the "Add manually" option in the app. This configuration method is usually more reliable than automatic device search.

You should also check that the phone is connected to the Wi-Fi network the thermostat or heater is meant to work with.

Thermostats support an external NTC 10 kΩ temperature sensor.

If the thermostat does not turn on, the first step should be to check the power supply — verify that voltage is reaching the device, that no protection device has tripped in the distribution board, and that the supply cables are correctly connected. If the thermostat still does not respond after checking the power supply, further diagnostics should be carried out by a qualified electrician.
