What is a programmable room thermostat?
... an explanation for householders
A programmable room thermostat is both a programmer and a room thermostat.
A programmer allows you to set ‘On’ and ‘Off’ time periods to suit your own lifestyle.
A room thermostat 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.
So, a programmable room thermostat lets you choose what times you want the heating
to be on, and what temperature it should reach while it is on. It will allow you to select
different temperatures in your home at different times of the day (and days of the week)
to meet your particular needs.
Turning a programmable 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
programmable room thermostat to a lower setting will result in the room being
controlled at a lower temperature, and saves energy.
The way to set and use your programmable room thermostat is to find the lowest
temperature settings that you are comfortable with at the different times you have
chosen, and then leave it alone to do its job. The best way to do this is to set low
temperatures first, say 18
°C , and then turn them up by one degree each day until you
are comfortable with the temperatures. You won’t have to adjust the thermostat further.
Any adjustments above these settings will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will usually be only one
programmable 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.

The time on the programmer must be correct. Some types have to be adjusted in spring
and autumn at the changes between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating programme, for example, ‘Override’,
‘Advance’ or ‘Boost’. These are explained in the manufacturer’s instructions.
Programmable 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.
INTRODUCTION
The RT500ROF is a programmable room thermostat with simple to operate energy
saving override control. Unlike standard programmable room thermostats the
programme on the programmable room thermostat can be temporarily overridden
using the remote override control.
The One Touch Override (OTO) is normally mounted at the main exit of the property
and is pressed on entry or exit. When activated, the OTO will override the programmed
temperature on the RT500 Programmable room thermostat.
YOUR RT500ROF INCLUDES THE FOLLOWING:

INSTALLATION OF RT500ROF
RT500 Programmable Room Thermostat
The RT500 can be used in any convenient location by using the included
stand, or can be easily installed in a fixed position using the industry
standard back plate supplied with the unit – this is used purely for mounting
purposes, as no wiring is needed for the RT500. The back plate can be
mounted directly to the wall surface.
The ideal position to locate the RT500 is 1.5m above floor level. It should be
mounted in a location where the thermostat is free from extremes of
temperature.
To ensure trouble free operation of the Radio Frequency (RF) signal, always
ensure that the programmable thermostat is mounted away from any
possible sources of interference (such as radios, TV sets, computers, etc) and
is not mounted on or in close proximity to large metal objects. Installing the
RT500 in enclosed areas such as basements is not recommended.
RT500 Jumper Settings
Changes to the jumper settings should only be made by the
engineer carrying out the installation or other qualified person.
The installer should select the jumper
positions required for programme or span if
changes need to be made to the factory default
settings. These jumpers are found on the rear of
the RT500. Jumpers 1-5 are for RF address
coding and are explained on page 14.
Jumper Function
Program 5-2 (factory default setting) or 7
individual days programming.
Span Temperature span of ± 0.5°C
(factory default setting) or ± 1.0°C

INSTALLATION OF RT500ROF
RT500 Receiver
NOTE: All electrical installation work should be carried out by
a suitably qualified Electrician or other competent person.
If you are not sure how to install this programmable thermostat
consult either with a qualified electrician, heating engineer or your
boiler / heating system supplier for advice on how to continue.
The RT500 Receiver should be mounted in a suitable location that is both
accessible for the connection of mains and control wiring, and allows good
reception of the RF signal. The Receiver needs a 230V AC mains supply to
operate, and this should be fused appropriately (13A max.). The Receiver
should be mounted in a location where it will
not come into contact with water, moisture
or condensation.
The On/Off switch is accessible from the front
face of the Receiver, as shown in this picture:
On the front cover of the Receiver you will see
that there is the On/Off switch and two Light
Emitting Diodes (LEDs). The switch allows
you to turn off the Receiver if necessary to
prevent it calling for heat.
The bottom LED (red) will illuminate when
the switch is in the ‘On’ position and the unit
is receiving power. The top LED (green)
illuminates when the Receiver unit is receiving
a heat call transmission from the RT500.
The wiring terminals and RF Address Code
setting DIP switches are located on the rear of
the Receiver, as shown in this picture:
Do not apply power until you are ready to
setup RF communications on page 13

RT500ROF INSTRUCTION MANUAL 13
TESTING THE RF COMMUNICATION
It is important to site the Receiver, One Touch Override and RT500 in
locations where the RF signal cannot be interrupted.
The receiving range between RT500, One touch Override and Receiver is 70
metres in open air, 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,
etc.
The range is generally large enough for most household applications, but it
is advisable to test the RF transmission from the intended RT500 and OTO
locations to the Receiver location before deciding where to mount the units.
To check the RF reception, follow the following steps:
1. Press the UP button on the RT500 until the set point
temperature is 3ºC higher than room temperature.
2. Wait for a few seconds. The flame indicator (heat call) should
appear on the bottom left of the LCD on the RT500.
3. Check the green LED on the receiver unit - it should be lit.
4. Select setback of OTO, press the big button to transmit the setback
signal to the Receiver. The green LED on the Receiver should be turned
off. This can test the RF range between the OTO and the Receiver.
5. Press the DOWN button of the RT500 to adjust the set point
temperature to be lower than room temperature.
6. Wait for a few seconds, and the flame indicator (heat call)
should disappear and the green LED should switch off.
7. Repeat steps 1 to 6 to make sure the LED in Receiver can turn on
and turn off each time.
If you are unable to get a stable RF connection between the Receiver and
RT500, check that the Receiver is both switched on and has a mains supply
(red LED lit). If this isn’t the problem you can also alter the RF address code
by following the ‘RF Address Code Setting’ section of this manual, and then
repeat steps 1 to 5. See page 14 and 15 of this manual.

RF COMMUNICATION FAULT FINDING
Normally, the RT500 can link with the Receiver and without pairing. If there
is another unit being used nearby, e.g. in the next house or as part of a
multiple installation, your Receiver may be fault triggered by the other
RT500. You can change the RF Address Code to help prevent this problem.
Each Receiver can only respond to RF transmissions from a RT500 that has
the same RF address code setting.
Disconnect any AC power to the Receiver, and remove the batteries from the
RT500 and One Touch Override module before attempting any adjustment
of the RF Address Code switches and jumpers. If you are not sure how to
carry out this operation correctly, consult either with a qualified electrician
or heating engineer or contact the SALUS Controls Technical Helpline for
advice on how to continue.
To adjust the RF address code of the Receiver, simply push up one or more
of the 5 DIP switch levers on the DIP switch bank located on the back of the
receiver (the levers are numbered 1 to 5 same as the RT500 Jumpers). On
the RT500 there are 5 jumpers and if you take 1 or more of the jumpers off
the RT500 you must switch the same numbers on the receiver to Off and
then press reset on the RT500.
RT500ROF Manual Ver039.qxp_89 21/10/2015 12:34 Page 14

RT500ROF INSTRUCTION MANUAL 15
To adjust the RF address code of the RT500,
remove one or more of the jumper caps
located on the back of the unit (labelled
1,2,3,4 and 5 shown in the picture
opposite) so that the jumper settings match
the settings made on the receiver:
For example, if the DIP switches
on the Receiver were set as follows:
1 - ON
2 - OFF
3 - OFF
4 - OFF
5 - ON
Then you would need to remove jumper caps 2, 3 and 4 on the
RT500 to make sure that they are both set with the same RF address
code. Please make sure that you keep any of the jumper caps you
remove in a safe place, in case you later need to change the RF
address setting again.
Turning on the Receiver at this point, the red LED will flash for 12
minutes to indicate the Receiver is in sync mode. During the pairing
process, the Receiver will go into NORMAL mode if the pairing
process is not completed within 12 minutes. After successfully
completing the pairing process, the red LED of Receiver will stop
flashing, then you can press the button of OTO to control the receiver
relay.
To pair the One Touch Energy Override Control with the Receiver,
gently press and hold the SYNC button for a few seconds with a sharp
object (such as the end of a paper clip). The front LED will flash every
few seconds and a RF address code will be generated and saved. The
OTO unit will continuously transmit the RF signal for 5 minutes to
the Receiver.
If the Receiver loses the signal from the OTO for more than 1 hour,
the red LED will flash, and the setback temperature will be cancelled.

PROGRAMMING THE RT500
The RT500 offers great versatility with its programming options, allowing
the user to programme the unit to operate on a 5/2 or 7 day control cycle.
The programmable thermostat has a default set of Programmes that have
been designed to meet the needs of most users. If these default programmes
are not suitable for your particular situation, reprogramming the RT500 with
your own settings is a very straightforward operation.
Selection of the default programming mode (5/2 or 7 day) is made by
changing the jumper setting on the rear of the RT500, as previously
described within the Installation section of this manual.
5/2 DAY MODE
5/2 day mode is the default programming mode for the RT500. With this
mode selected, five different sets of time and set point temperatures can be
set for Weekdays or Weekends.
To review or change a programme, press the SET key when the RT500 is in
Normal mode. This will change the unit status to Programme Setting mode.
The LCD display will display
programme number 1 and SET
PROG, with all other indicators
cleared. The weekdays will be
