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.
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
