PNI CT25T Smart WIFI Radiator Thermostat  

Product presentation

PNI CT25T is a thermostat that measures the air temperature and regulates according to this the water flow inside the radiator. This thermostat does not control the heating boiler. Install a thermostatic head on each radiator and set the desired temperature for each room. How fast the temperature in a room rises depends on the settings made in the boiler and the size of the radiator. For a correct measurement of the ambient temperature, the thermostatic head must not be covered by curtains or blocked by pieces of furniture.
