Installation
 First, remove the wallplate from the back of the unit.
 From the top left hand corner of the wallplate, there must be
clearances of at least 140mm to the right, 15mm to the left,
30mm above and 100mm below in order to mount the plug-
in module.
Installation Instructions
GB

5
 Prior to mounting the unit should be set in either ON/OFF or
chrono-proportional control mode (see below).
ON/OFF - boilers switches ON when below set temperature
and OFF when above.
Chrono-Proportional - energy saving feature which res
the boiler at regular intervals to maintain a set temperature,
achieving a constant ambient environment for the user.
Some existing thermostats will have a Neutral wire and/or
Earth wire connected. These are not required by the RT51/52
and must NOT be connected to any RT51/52 terminals. Instead
they should be made electrically safe and coiled in the recess at
the back of the RT51/52.

Commissioning (RF models only)
Ifthethermostatandthereceiverhavebeensupplied together
in a combined pack, the units have been paired in the factory
and no commissioning is required (RX1 only).
To tune the RX receiver to the frequency of the thermostat signal,
follow steps 1-5 below.
Step 1 RT51/52-RF
Reset the unit by removing the
batteries for 2 minutes, then replace.
Step 2 Press and hold V and +
buttons for 3 seconds (Thermostat now
transmits unique signal continuously
for 5 minutes).
Step 3 RX1
Press and hold buttons PROG and CH1
for 3 seconds until green light ashes
once.
Step 4 RX2 (if applicable)
Stat 1 - perform steps 1-3.
Stat2-wait5mins,performsteps1-2and
then press PROG and CH2 on RX2.
RX3 (if applicable)
Stat 1 - perform steps 1-3.
Stat 2 - wait 5 mins, perform steps 1-2 and then press PROG and
CH2 on RX3.
Stat 3 - wait 5 mins, perform steps 1-2 and then press PROG and

What is a programmable 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.
The heating system will not work if a time switch 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 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 will waste energy and cost yo u 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, wallortablelampsmaypreventthe thermostat
from working properly.

Your room thermostat
RT51
The RT51 is a simple to use room thermostat which allows you
to programme a Day and a Night temperature, and to switch
between the two settings simply by pressing 2 buttons.
RT52
The RT52 has the same functionality as the RT51 with the added
benet of a built-in timer, which will return the thermostat to Day
temperature at a time chosen by you.
Wireless RF versions
Both models are available in wireless versions - RT51-RF and RT52-
RF - which oer exactly the same functions as the hard-wired
models.
Each thermostat communicates with an RX receiver, which can be
located up to 30m away.
