Important note RF products: Ensure that there are no large metal objects, such as boiler
cases or other large appliances, in line of sight between the transmitter and receiver as
these will prevent communication between thermostat and receiver.

If the thermostat and the receiver have been supplied
together in a combined pack, the units have been paired in
the factory and no commissioning is required (RX1 only).
Step 1 RET B-RF
Position the setting dial to number
1. Remove dial, press & hold LEARN
button for 3 seconds (located under
setting dial).
Do not replace the setting dial yet
NOTE: Thermostat now transmits
signal continuously for 5 mins.

What is a room thermostat?
... an explanation for householders. A room thermostat simply
switches the heating system on and o 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 o
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 aect 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.
User Instructions

11
The heating system will not work if a timeswitch or programmer has
switched it o.
The way to set and use your room thermostat is to nd 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 1C 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 dierent 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 ow of air to sense the temperature,
so they must not be covered by curtains or blocked by furniture.
Nearby electric res, televisions, wall or table lamps may prevent the
thermostat from working properly.

Display
The LCD displays actual room temperature until the setting dial
is moved.
Setting the temperature
Turn setting dial to required temperature. The selected
temperature will ash in the LCD to signify it is showing set
temperature.
After a short period the display stops ashing and shows actual
room temperature.
Thermostat status (heat mode only)
A ame symbol will be lit whenever the thermostat is calling
for heat.
User Instructions
GB
13
Thermostat status (cool mode only)
A snowake symbol will be lit whenever the thermostat is
calling for cooling. If this is seen to ash, the thermostat output
is delayed for a short period to prevent compressor damage.
Low battery indication
A battery symbol will ash in the display when batteries require
replacement. Batteries should be replaced within 15 days, after
which the thermostat will turn o the load it is controlling.
When this happens “Of will be displayed.
IMPORTANT: alkaline batteries must be used.

RET B-LS model only
This model istted with an Auto/O switch.
When the switch is set in “I position the thermostat
controls at the temperature set by the setting dial.
When set to “O” the thermostat output is turned o and
Of is displayed.
RET B-NSB model only
This model istted with a Day/Night switch.
When the switch is set to the “Sun Symbol”, the thermostat
controls at the temperature set by the setting dial.
When set to the “Moon symbol”, the thermostat controls
at C below the temperature set by the setting dial.
NOTE: if used to control cooling, thermostat controls C higher, with
switch in MOON position.
