Frequent questions

What is Smart Thermostat?
The Smart Thermostat allows you to set the temperatures of the areas of your home, and is also able to detect the temperature, humidity and air quality of the area of the house in which it is located. The thermostat measures 168x88x24 mm and will be sent to you with the following accessories: 2 non-rechargeable AA alkaline batteries, 2 screws for wall fixing.
How can I check the compatibility of the Smart Thermostat with my system?
The Smart Thermostat can replace any wired thermostat on the market: in fact, it works on batteries and can also be connected to the boiler by relay. In order to check if our thermostat to your system more precisely, you can use the configurator (link).

If you want to place the Smart Thermostat in a different place from the original one without masonry works (drilling walls, cable passage and the like), but you still need the thermostat to control the on/off of the boiler, you can install the Smart Thermostat by connecting it to the boiler via relay. Alternatively, you can add the Starter IRSAP NOW (product link), install it directly on the boiler, delete the old thermostat and place the Smart Thermostat wherever you like.
