Hi I have a old Landis&Staefa room stat, but I can't turn it down beyond 20 degrees. If I do turn it on a lower setting the boiler cuts out. Any ideas.

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.

What is the best place to mount a thermostat? Verified

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.
