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.
