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.
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.
T
make the room heat up any faster
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.
T
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 18
o
C,
and then turn them up by one degree each day until you are
comfortable with the temperatures. Y
thermostat further
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.
Y
ou may be able to temporarily adjust the heating programme, for
example, ‘Override’, ‘
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
