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
comfortable with the temperature. 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.
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.
The above explanation has been kindly provided by the association of heating controls
manufacturers as a guide to encouraging the correct and efficient use of heating controls.
The AS2-RF thermostat kit is made up of two parts:
1 x ASR-RF Receiver
1 x AS2-RF Transmitter
Both parts have been designed to be easily installed and offer maximum flexibility. No hard
wiring is required between the transmitter and the receiver. The receiver unit is hard wired to
the boiler and should be sited close to the existing wiring. The AS2-RF can then be positioned
up to 30 metres away -
Range will vary depending upon the composition, density and number
of walls between the AS2-RF transmitter and the receiver.

**The override facility will only operate
when a flashing amber LED is showing. This
indicates no signal from the AS2-RF
transmitter is being received, the position
and battery level should be checked.
