INTRODUCTION

A thermostat is a device that is used to switch the heating system in your home on and off as needed. It

works by sensing the air temperature and switching on the heating when the air temperature falls below

the thermostat setting, and switching it off once the set temperature has been reached.

The ST320RF from Salus Controls is a stylish and accurate electronic thermostat with a large, easy to

read LCD display. The thermostat has been specifically designed to be used Volt Free. 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.

The use of the revolutionary Touch Ring technology makes for

simple usage, and is coupled with a unique, smart design. The

LCD display will show the current room temperature and the ‘one

touch’ operation makes the ST320RF easy to operate.

INSTALLATION

Please read the important safety information at the start of this manual before you start to install the device.

The ideal position to locate the 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 ST320RF in enclosed

areas such as cellars and basements is not recommended.

CONNECTING THE ST320RF 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 digital thermostat consult either with a qualified

electrician, heating engineer or your boiler / heating system supplier for advice on how to continue.

The ST320RF 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 (16A max.). The Receiver should be

mounted in a location where it will not come into contact with water, moisture or condensation. Please

be reminded that touch can be held up by condensation on the touch ring surface and can reduce

sensitivity.

There are few electrical connections required to the ST320RF, and these connections should be made to

the terminal block inside the Receiver. No Earth connection is required for the correct and safe operation

of the ST320RF, but a parking terminal is provided to connect an Earth wire if one is present.

These electrical connections are shown in the table below:

INSTALLING AND REPLACING BATTERIES

Installing or replacing the ST320RF Control Centre batteries is

a straightforward operation, but does require you to open the

case of the thermostat.

To open the ST320RF case, undo the securing screw on the

bottom of the case (just to the right of the hole for the Reset

Button):

After undoing the screw pull it forward until the screw stops

moving, then carefully separate the two halves of the case

by gently pulling in an upwards direction. Once the case has

been separated, the batteries should be visible:

Ensure that the batteries are inserted correctly, paying

careful attention to the polarity markings on the battery and

next to the battery holders. After inserting the batteries, refit

the ST320RF case and retighten the securing screw.

PAIRING THE ST320RF RECEIVER AND CONTROL CENTRE

It is important to correctly pair both the Receiver and Control Centre to ensure that the RF address codes

are matched and that reliable communication is established between the units. Please follow the

instructions below to ensure that the units are configured correctly.

ON THE RECEIVER:

Press and hold the SYNC button to allow the Receiver to enter the learning mode. The Red SYNC LED will

turn on to indicate it is ready to receive a signal and pair with another unit.

While the signal is being received, the SYNC LED will turn on until the pairing has completed successfully;

the SYNC LED will then turn off and the Green Power LED will turn on again. The Control Centre will

continue to transmit a pairing signal for 10 minutes before returning to NORMAL mode.

The ST320RF Control Centre display will change to show a rundown timer:

The unit counts down for a period of 10 minutes, with the RF Signal indicator flashing while the signal

is being transmitted. The RF address code will be generated randomly and the Control Centre will

transmit the signal every second for the full 10 minutes until:
