What is a room thermostat?

...an explanation for householders

A room thermostat simply switches the heating
system on and off as necessary. It 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.

Turning a 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 room thermostat to a
lower setting will result in the room being controlled
at a lower temperature, and saves energy.

The heating system will not work if a time
switch or programmer has switched it off.

The way to set and use your room thermostat
is to find the lowest temperature setting
that you are comfortable with, and then
leave it alone to do its job. The best way to
do this is to set the room thermostat to a
low temperature – say 18ºC – and then

turn it up by one degree each day until
you are
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 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.

TRT products are a cost effective
comprehensive range of thermostats and
timers designed for internal use only.

The TRT030 is an electronic room
thermostat, with an easily adjustable dial.
It has optional PID control (which can help
to minimise temperature overshoot), and
adjustable swing (difference between on
and off switching temperatures), from
1ºC to 0.5ºC.

It is designed to be surface mounted
on its supplied wall plate.

The electrical supply must be isolated
before removing the thermostat from
the wall plate.
