1. 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.

Salus ST620WBC Manual 013_89 09/02/2012 14:01 Page 6
Powering up the ST620 for the first time
As soon as the batteries have been inserted, the ST620 will power up for the first time and behave
in the following way:
All the segments on the display along with the display backlight will be turned on as shown.
After two seconds, the software version number will be briefly on the screen.
The ST620 will now prompt you to choose a language. If you require ENGLISH press OK. If you require
a different 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 flashing.
This will continue to flash 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 29.
Now put the ST620 front fascia in a safe place so you can mount the ST620 back plate. The back
plate is easily fixed 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 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 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 floor level.
RF Transmission
The receiving range between ST620 and the RF Boiler Control is around 100 metres in open air, however many factors can affect
the RF transmission and shorten the operating distance, e.g. shielding by thick walls, foil back plasterboard, metal objects
such as filing 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
