INTRODUCTION
A programmable 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 RT500RF from Salus Controls is a stylish and accurate 5/2 or 7 day
programmable electronic thermostat with a large, easy to read Liquid Crystal
Display (LCD). 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 control systems. Unlike ordinary single
unit design thermostats, this is a new type of thermostat separating the
operational functions into two units.
The Receiver is used for wiring connections and heat on/off control. The Control
Centre 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 LCD 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 RT500RF Control Centre 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 Control Centre.
The back plate can be mounted directly to the wall surface.
The ideal position to locate the RT500RF Control Centre 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 RT500RF in enclosed areas such as
cellars and basements is not recommended.
CONNECTING THE RT500RF 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 RT500RF 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 Receiver 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 top LED (red) will
illuminate when the switch is in the ‘On’ position and the unit is receiving
power. The bottom LED (green) illuminates when the Receiver unit is
receiving a heat call transmission from the Control Centre.
The wiring terminals and RF Address Code
setting DIP switches are located on the
rear of the Receiver, as shown in this
picture:

CONTROL CENTRE 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 if changes need to be
made to the factory default settings. These
jumpers are found on the rear of the
Control Centre.
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
corresponding DIP switch on the Receiver.
NOTE:
The Reset button must be pressed after changing jumper positions.

RF ADDRESS CODE SETTING
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
Control Unit. You can change the RF Address Code to help prevent this
problem.
Each Receiver can only respond to RF transmissions from a Control Centre
that has the same RF address code setting.
Disconnect any AC power to the Receiver, and remove the batteries from the
Control Centre 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.
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 from bottom to top, as shown in the
picture below), and then make a note of the setting of each switch:
