INTRODUCTION
A programmable room thermostat is a
device that combines the functions of
both a room thermostat and heating
controller into a single unit. The
programmable thermostat is used to
switch the heating system in your home
on and off as needed. It works by
controlling the temperature according to
a series of programmed settings that take
effect at different times of the day.
The RT500 programmable room thermostat from Salus Controls is a stylish and
accurate 5/2 or 7 day programmable electronic thermostat with a large, easy to
read display. This programmable thermostat has been specifically designed to
be used for both Volt Free and AC heating applications. This programmable
thermostat can replace most common residential thermostats and is designed
to be used with electric, gas or oil heating boilers. Unlike ordinary single unit
design thermostats, this is a new type of thermostat separating the operational
functions into two units.
The RF Boiler Control is used for wiring connections and heat on/off control. The
RT500 provides the user interface and temperature sensing / control. The two
units are linked together by a Radio Frequency (RF) signal.
Features
•Volt free switching option
•5/2 or 7 day programming flexibility
•Built-in start up programming for quick installation
•Frost protection
•Large, easy to read display with blue backlight
•Burner on symbol
•Easy to use programming
•User friendly

INSTALLATION
Please read the important safety information at the start of this manual
before you begin to install the device.
The RT500 programmable room thermostat is easily installed 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 about 1.5m above floor level. It
should be mounted in a location where the thermostat is accessible,
reasonably lit and free from extremes of temperature and draughts. Do not
mount the thermostat on an outside wall, above a radiator or in a location
where it may be subjected to direct sunlight.
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 cellars and basements is not
recommended.
CONNECTING THE RT500 BOILER CONTROL
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 the Boiler Control consult either with a
qualified electrician, heating engineer or your boiler / heating system
supplier for advice on how to continue.

RT500 THERMOSTAT DEFAULT SETTINGS
Changes to the default settings should only be made by the Engineer
carrying out the installation or other qualified person.
The installer should select the “jumper”
positions required if changes need to be
made to the factory default settings. The
“jumpers” are found on the rear of the
RT500.
Jumper Function
Program Jumper for 5-2 (factory default setting) or 7
individual days programming.
Span Movable jumper for selecting temperature span
of ± 0.5°C (factory default setting) or ± 1.0°C
1,2,3,4,5 Removable jumpers for altering the RF address
code when used in conjunction with the
teaching mode of the boiler control.
NOTE:
The Reset button must be pressed after changing jumper positions.

CHANGING THE BATTERIES ON THE RT500
1. Open the front flap on the right hand side of the unit ,
this reveals the SET & SELECT buttons
2. On the bottom right hand side pull the small flap down
which will reveal the batteries as shown above.
3. Remove the old batteries
4. Now insert the new batteries, insert bottom battery with
the“+” end first followed by the top battery “ – “first .
Note:
When changing the batteries the RT500 will save your settings for 10
sec, after 10 seconds your settings will be lost

RF ID CODE SETTING
Normally, the RT500 can link with the Boiler Control the ID code setting. If
there is another unit being used nearby, e.g. in the next house, your Boiler
Control may be triggered by the other RT500. You can change the RF ID
Code to help prevent this problem.
Each Boiler Control can only respond to RF transmissions from a RT500
with the same RF ID code setting.
To adjust the RF ID code of the RT500,
remove one or more of the jumper
caps located on the back of the unit
(labelled 1 to 5 as shown in this
picture): Then follow the steps below
to resync the RF communication.

SYNCHRONISING THE BOILER CONTROL
(a) RT500 programmable room thermostat RF Sync mode
- Press and hold "SELECT" to enter ID transmission;
ID code is set by 5 position jumper switches;
- TX sends ID code for 10 minutes.
- during 10 minutes synchronisation, LCD shows "Sy" on
temperature digits and the timer will count down.
- during 10 minutes synchronisation, pressing any key can interrupt ID
code transmission and LCD will return to normal mode, i.e.
temperature and clock.
(b) Boiler Control RF Sync mode
- Press and hold "SYNC" button on the boiler control for a few seconds to
enter ID learning mode, LED flashes.
- Until ID is captured and memorized into EEPROM (within max 12
minutes), LED stops flashing and stays ON (relay close) or OFF (relay
open) if ID is never captured, LED will keep flashing to alert user to
re-sync, until 12 minutes timeout.
To pair the RT500 to the Boiler Module simply press and hold the sync
button on the Boiler module for 3 seconds, at the same time press and
hold Select on the RT500 for 3 seconds, after 3 seconds at the same time
release both the sync button on the boiler module and the select button on
the RT500.
If the Boiler Control successfully receives a signal from the RT500 during the
pairing operation, the Boiler Control will store the new RF address code into
its internal memory. The LED will flash twice if the code is stored correctly,
or 4 times if this was unsuccessful. The Boiler Control will then exit pairing
mode and the LED will go out.
