Introduction
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 18⁰C – 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.

Installation
Note: Please insert batteries into the RT310RF thermostat and it will power up..
DIP switch settings
The DIP switches are found on the rear of your thermostat and can be used to
change the span (temperature accuracy) of your thermostat from the default
+/-0.5°C to +/-0.25°C. This may cause your boiler to operate more frequently.
The DIP switches are located on the back of the thermostat. ON +/-0.25°C, OFF
+/-0.5°C. The span is the accuracy with which the thermostat operates when
displaying your temperature. You can increase the accuracy by setting the span
to +/-0.25°C, meaning that your thermostat will be sensitive to a quarter of a
degree temperature change and will activate/deactivate the boiler.
Connecting the RXRT510 receiver
Unscrew the backplate of the RXRT510 receiver in order to do the wiring
connections. After that please switch the receiver ON.

Test Pairing Function
Make sure your devices are wired and the thermostat has batteries inserted.
Switch receiver to ON. If you are using the RT310RF pack, the pairing between
the thermostat and the receiver is already done. If you bought the RT310TX and
RXRT510 separately then pair as follows. Please make sure that the Receiver is
set on Auto.
Note: Before beginning the process, switch the receiver On/Off and then On again to reset it (On/Off/On).
Testing the RF transmissions
It is important to site both the Receiver and thermostat in locations where
the RF signal cannot be interrupted. The receiving range between the
thermostat and Receiver is approximately 30 metres indoors, however many
factors can affect the RF transmission and shorten the operating distance,
e.g. shielding by thick walls, foil back plasterboard, metal objects such as
filing cabinets, general RF interference, and so on. The range is generally
large enough for most household applications, but it is advisable to test the
RF transmission from the intended thermostat location to the Receiver location
before fixing the thermostat to the wall.
To check the RF reception, follow the following steps:
- Press the UP button on the thermostat until the set point temperature is higher than room temperature by a few degrees.
- Wait for a few seconds. The Heat on (heat call) indicator should appear on the bottom left of the LCD on the thermostat.
- Check the green LED on the receiver unit – it should be lit.
- Press the DOWN button to adjust the set point temperature to be lower than room temperature.
- Wait for a few seconds, and the Heat on (heat call) indicator should disappear and the green LED should switch off.
- If at step 3 the green LED is not illuminated, press the TEST/PAIRING button on the thermostat and try to place the thermostat closer to the Receiver.
- Repeat steps 1 to 5.
Installer Mode
Press and hold and and keys to enter installation setting.
The first setting is temperature display resolution selection – d01. Press to
