PNi CT25T Smart radiator thermostat is designed to measure air temperature and control the water flow from the radiator accordingly. Install a thermostat head on each radiator and set the desired temperature for each room individually. The speed at which the temperature rises in a room depends on the boiler settings and the size of the radiator. The package includes a set of six adapters to ensure compatibility with different thermostatic valves (Danfoss, Giacomini, Caleffi, etc.).

You can schedule temperature settings by day, allowing you to set up to four time periods for each day of the week, each with its own temperature limit. For example, you can set the following time periods in one day:

• 06:00 - 23 degrees
• 08:00 - 22 degrees
• 17:00 - 23 degrees
• 23:00 - 22 degrees.

In the "Advanced settings" menu, you can adjust parameters for various functions, including hysteresis, frost protection temperature, child protection function, and "open window" function.

If the child protection function is activated, the thermostat's keys are locked. The function becomes active as soon as the backlighting of the screen goes out.

With the frost protection function, you can set a temperature level between 5 °C and 15 °C in the "Advanced settings" menu, which will be maintained while you are away from home.

The PNI CT25T thermostatic head can be controlled remotely using the PNI CT25WIFI hub (sold separately). By pairing the two devices and adding the hub in the Tuya Smart application, you can perform various operations remotely, including setting the temperature, switching the thermostat on or off, changing the operating mode, and setting the weekly program.
