What is a programmable room
thermostat?
...an explanati n f r h useh lders
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.
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.
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.
The way to set and use your programmable room
thermostat is to find the lowest temperature settings that
you are comfortable 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.
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 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.
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.
You may be able to temporarily adjust the heating
programme, for example, ‘Override’, ‘Advance’ or ‘Boost’.
These are explained in the manufacturer’s instructions.
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.
