The heating system will not work if a timeswitch or programmer has 

switched it off.

The way to set and use your room thermostat is to find the lowest 

temperature setting that you are comfortable with, and then leave it 

alone to do its job. The best way to do this is to set the room thermostat 

to a low temperature – say 18°C – and then turn it up by one degree 

each day until you are comfortable with the temperature. You won’t 

have to adjust the thermostat further. Any adjustment above this 

setting will waste energy and cost you more money.

If your heating system is a boiler with radiators, there will usually 

be only one room thermostat to control the whole house. But you 

can have different temperatures in individual rooms by installing 

thermostatic radiator valves (TRVs) on individual radiators. If you don’t 

have TRVs, you should choose a temperature that is reasonable for the 

whole house. If you do have TRVs, you can choose a slightly higher 

setting to make sure that even the coldest room is comfortable, then 

prevent any overheating in other rooms by adjusting the TRVs.

Room thermostats need a free flow of air to sense the temperature, 

so they must not be covered by curtains or blocked by furniture. 

Nearby electric fires, televisions, wall or table lamps may prevent the 

thermostat from working properly.
