RT500RF INSTRUCTION MANUAL

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.

RT500RF INSTRUCTION MANUAL

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.

RT500RF INSTRUCTION MANUAL

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:
