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.

to a setback level and the ‘On’ button can also be used to adjust the
temperature to a comfort level.
The setback feature is designed for those interested in saving energy
and have a varied lifestyle. It means that when leaving the house for
a shopping trip or a night out, the user can adjust the temperature
to a lower level by pressing the ‘Off’ button, with the comfort level
restored on their return by pushing the ‘On ‘button.
NB. This feature can be used to quickly adjust the temperature
setpoint to a setback temperature for economy operation if for
example, ‘Off’ Temperature = 15ºC and the On temperature can
be used to quickly adjust the temperature setpoint to a comfort
temperature if for example ‘On’ Temperature = 22ºC.

When the batteries start to run low a battery icon will flash in the display, to
indicate “low battery” during this time the Digistat +1RF will function normally

Please replace batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries.
When the battery icon alone is shown in the display, the batteries are completely
exhausted and the Digistat +1RF will cease to function (see fig 2). Re-activate by
replacing the batteries.
