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 – say 18
o
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 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.
USER GUIDE
TLX 7506
DIGITAL ROOM THERMOSTAT
Installation
Please read all installation instructions before starting.
The TLX 7506 Digital room thermostat is battery powered and operated by radio control. It does not require any electrical connections.
If it is replacing an existing hard wired thermostat, isolate and make safe the wiring to the old thermostat, as it is no longer required.
All electrical wiring changes must be carried out by a competent person in accordance with the latest appropriate wiring regulations. Be
sure to switch off the Mains supply before removing any existing thermostat.
Position
The ideal position to locate the TLX 7506 Digital room thermostat, is about 1.5M above floor level, accessible, reasonably lit and free
from extremes of temperature and draughts. Do not mount on an outside wall, above a radiator or where it will be subject to direct
sunlight.
The wireless nature of the installation means that the thermostat can now be positioned in any room to provide optimum thermal
response, rather than to minimise or simplify the installation wiring.
It is recommended that the commissioning procedure be carried out before fixing the mounting plate to ensure the chosen locations are
suitable for transmitting and receiving radio signals.
