DRF Room Thermostat
What is a room thermostat?
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, at say
18°C 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 may waste energy.
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 fires, televisions, wall or table
lamps may prevent the thermostat from working properly.

The display normally shows the current room
temperature to within 0.5°C
■ ■
To adjust the required temperature, turn the dial
clockwise to increase or anti-clockwise to decrease,
(1 click = 1°C), the LCD will display the temperature
setpoint as it is being adjusted and ‘SET’ will be
displayed. After a few seconds the display will return
to normal operation and will display the actual room
temperature.
While adjusting the temperature during normal
operation, when you reach the maximum or minimum
possible setting the display will flash to indicate you
cannot adjust the product further.
