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.
