What is a Programmable Room Thermostat?
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 1°C 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
programmable room thermostat to control the whole house. But you can have
dierent 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.
You are able to temporarily adjust the heating program by overriding or using the
temperature hold feature. These features are explained further on pages 14 and 15 of
this manual.
Programmable room thermostats need a free ow of air to sense the temperature,
so they must not be covered by curtains or blocked by furniture. Nearby electric
res, televisions, wall or table lamps may also prevent the thermostat from working
properly.
A programmable room thermostat is both a programmer and a room thermostat.
The programmer allows you to set “On” and “O” periods to suit your own lifestyle.
The room thermostat works by sensing the air temperature, switching on the heating
when the air temperature falls below the thermostat setting, and switching it o once
this set temperature has been reached.
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
dierent temperatures in your home at dierent times of the day (and days of the week)
to meet your particular needs and preferences.
Setting a room thermostat to a higher temperature will not make the room heat up
any faster. How quickly the room heats up depends on the design & size of the heating
system.
Similarly reducing the temperature setting does not aect how quickly the room cools
down. Setting a programmable room thermostat to a lower temperature will result in the
room being controlled at a lower temperature, and saves energy.
The way to set and use your programmable room thermostat is to nd the lowest
temperature settings that you are comfortable with at the dierent times you have
chosen, and then leave it alone to do its job.
