The best place for the thermostat is the room where you spend the most time, in many cases the living room or kitchen. Place the thermostat about one and a half metres above the floor, not in the sun and not on an outside wall.
If your thermostat has a dead band, your installation is, as it were, 'at rest'. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.
Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.

Number of questions: 5Mark as room temperature the same temperature that I set for the boiler to start and it doesn't return to show the actual temperature in the room at that moment. In other words, what it shows at rest is the one I have chosen to start the boiler.
