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 eect at dierent
times of the day.
The ST620ROF 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
specically 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/o control. The ST620 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 ST620ROF 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 ST620 programmable thermostat is about 1.5m above oor 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 ST620 should be mounted in a location where it will not come into contact with moisture or
condensation, as this can aect 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 ST620 in enclosed areas such as cellars and basements is not recommended.

CONNECTING THE ST620ROF RECEIVER
NOTE: All electrical installation work should be carried out by a suitably qualied Electrician or other competent
person. If you are not sure how to install this digital thermostat consult either with a qualied electrician, heating
engineer or your boiler / heating system supplier for advice on how to continue.
The ST620ROF 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 ST620ROF, 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 ST620ROF, but a parking terminal is provided to connect an Earth wire if one is present.
These electrical connections are shown in the table below:
Terminal Function
COM Common Contact
NO Normally Open Contact
Earth Parking (No electrical connection)
L Incoming Mains - Live
N Incoming Mains - Neutral

RECEIVER WIRING TERMINALS
The receiver cover can be removed from its back plate by
unscrewing the grub screws under the front face and slowly pull
them apart .
Please note: These screws DO NOT need to be fully removed.
Once the cover is fully removed the terminals will become
exposed ready for installation.

2. INSTALLATION
ST620 Programmable Room Thermostat
Getting Started…
Installing the ST620 Batteries
To open the case of the ST620, undo the securing screw on the
bottom.
Now pull the screw down until it stops, then carefully separate the
two halves of the case by gently pulling out an upwards direction.
You will now see the battery compartments on the rear of the front
fascia as shown.
Ensure that the batteries are inserted correctly and check the
polarity.
08 ST620ROF INSTRUCTION MANUAL
SALUS ST620ROF Manual 003.qxp_89 11/08/2015 09:45 Page 8
As soon as the batteries have been inserted, the ST620 will power up for the rst time and behave
in thefollowing way: All the segments on the display along with the display backlight will be
turned on as shown.
The ST620 will now prompt you to choose a language. If you require ENGLISH press OK.
If you require a dierent Language use the touch ring to scroll through the language options then
press OK.
The ST620 at this point will be in AUTO and at factory default settings. Changing default settings
will be explained in sections 4 & 5. You will also notice that the time at the top of the LCD is
ashing. This will continue to ash until the unit picks up the RCC (Radio Controlled Clock) signal
and displays the correct time. More information on the RCC can be found on page 28.
Now put the ST620 front fascia in a safe place so you can mount the ST620 back plate. The back
plate is easily xed to the wall and uses industry standard mounting positions. We recommend
that you continue with the back plate mounting before starting to program the ST620.

Note: If you do not wish to mount the ST620 on the wall, use the stand provided and
assemble the ST620 front and back housing. Remember to tighten the screw at the bottom.
Wall Mounting Guidelines
The ST620 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 ST620 should be mounted in a location where it will not come into contact with moisture or
condensation as this can aect 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 ST620 in enclosed areas such as cellars and basements is not recommended.
NOTE: The ideal position to locate the ST620 is about 1.5m above oor level.
RF Transmission
The receiving range between ST620 and the RF Boiler Control is around 100 metres in open air, however many factors can
aect the RF transmission and shorten the operating distance, e.g. shielding by thick walls, foil back plasterboard, metal objects
such as ling cabinets, general RF interference, and so on.
The operating range is generally around 30 metres, which is large enough for most
household applications.
Mounting the Back plate
Use the screws and anchors supplied to mount the ST620 back plate in your chosen
position. Now attach the ST620 front fascia to the back plate. Remember to tighten the
securing screw.
