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 by means of time
and temperature change. This unit is not like a standard programmer. It works by controlling the temperature
according to a series of programmed settings that take effect at different times of the day.
The ST620RF 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 Volt Free. Unlike ordinary single unit design programmable thermostats,
this is a new type of unit that separates 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 ST620RF easy to operate.

INSTALLATION
Please read the important safety information at the start of this manual before you begin to install the device.
The ideal position to locate the ST620RF programmable thermostat 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.
The ST620RF should be mounted in a location where it will not come into contact with moisture or condensation,
as this can affect the Touch Ring operation.
To ensure trouble free reception for both the Radio Controlled Clock (RCC) and 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 ST620RF in enclosed areas such as cellars and basements is not recommended.

CONNECTING THE ST620RF 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 ST620RF 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. There are few electrical connections required to the ST620RF, 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
ST620RF, 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 ST620RF Control Centre batteries is a
straightforward operation, but does require you to open the case of
the programmable thermostat.
To open the ST620RF 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 ST620RF case
and retighten the securing screw.

PAIRING THE ST620RF 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.
On the Control Centre:
The Arrow key is not active when the ST620RF is in NORMAL mode. To access the Menu screens,
press the OK key twice. The first menu displayed is the PROGRAMME menu:
ST620RF INSTRUCTION MANUAL8
ST620RF Manual Version 005 CMYK:Layout 1 1/9/10 11:56 Page 8
Use the Touch Ring to scroll through the Menus, and press the OK key to select the menu you want to use:
You can scroll through the menus in either direction (forwards or backwards) depending on the direction you move
your finger around the Touch Ring. The menus are displayed in the order shown in the picture above.
Pressing the Arrow key will return the ST620RF to NORMAL mode. The thermostat will also return to NORMAL mode
after 10 seconds if no Key is pressed or if no movement is detected on the Touch Ring.
9ST620RF INSTRUCTION MANUAL
ST620RF Manual Version 005 CMYK:Layout 1 1/9/10 11:56 Page 9
After selecting the PAIR Menu, PAIR and the RF icon are displayed.
Press the OK key to start sending the RF address code to the Receiver.
The ST620RF 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:
• The Arrow key is pressed to return to the previous display
• The OK key is pressed to return to NORMAL mode
• The 10 minute timer runs out
Note that the Receiver must be already in learning mode BEFORE attempting to access the PAIR menu on the Control
Centre. If the Red SYNC LED has not turned off after 10 minutes, repeat the whole pairing process.
Pressing the Reset button on the Control Centre and the Receiver will clear the RF address code and generate a new
default code which will be saved into the internal memory of the unit; there is no need to re-pair the Receiver and
Control Centre. This is a quick and easy way to directly link the units in many applications.
