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.

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