with at the different times you have chosen, and then leave  
it alone to do its job. The best way to do this is to set low  
temperatures first, say 18C, and then turn them up by one  
degree each day until you are comfortable with the  
temperatures. You won’t have to adjust the thermostat further.  
Any adjustments above these settings will waste energy and cost  
you more money.  
What is a programmable  
room thermostat?  
…an explanation for householders  
A programmable room thermostat is both a programmer and a  
room thermostat. A programmer allows you to set ‘On’ and  
‘Off ’ time periods to suit your own lifestyle. A room thermostat  
works by sensing the air temperature, switching on the heating  
when the air temperature falls below the thermostat setting, and  
switching it off once this set temperature has been reached.  
If your heating system is a boiler with radiators, there will usually  
be only one programmable room thermostat to control the  
whole house. But you can have different temperatures in  
individual rooms by install-ing 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.  
So, a programmable room thermostat lets you choose what  
times you want the heating to be on, and what temperature it  
should reach while it is on. It will allow you to select different  
temperatures in your home at different times of the day (and  
days of the week) to meet your particular needs.  
Turning a programmable room thermostat to a higher setting  
will not make the room heat up any faster. How quickly the  
room heats up depends on the design of the heating system, for  
example, the size of boiler and radiators.  
The time on the programmer must be correct. Some types have  
to be adjusted in spring and autumn at the changes between  
Greenwich Mean Time and British Summer Time.  
Neither does the setting affect how quickly the room cools  
down. Turning a programmable room thermostat to a lower  
setting will result in the room being controlled at a lower  
temperature, and saves energy.  
You may be able to temporarily adjust the heating programme,  
for example, ‘Override’, ‘Advance’ or ‘Boost’. These are explained  
in the manufacturer’s instructions.  
The way to set and use your programmable room thermostat is  
to find the lowest temperature settings that you are comfortable  
Programmable 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.
