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.

room thermostat Honeywell CM5000 no longer correctly displays the room temperature, could it be that the internal thermostat is no longer working correctly? As a result, we have to set the thermostat to too high a temperature in manual mode. Can the built-in temperature measurement be adjusted or reset?
