What is the dead zone of a thermostat? Verified
Many modern thermostats have a dead zone. If the temperature deviates less than 4°C from the set temperature, the system will not heat or cool. This so called dead zone of the thermostat prevents the system from turning on and off too often, saving energy.

The best place for a thermostat is approximately 1,5 meter above the ground. Never place the thermostat nead a radiator or other heat emitting equipment or in direct sunlight. Choose a room that is used often. In most cases this is the living room.

Before the batteries run out the display will show a warning that the batteries need to be replaced. When this does not happen in time and the batteries run out, the system will go into frost protection mode and start heating constantly. During summer this may lead to uncomfortably high temperatures inside.
