ENERGY TIP
One way to set and use your room thermostat is to find the lowest temperature setting that you are comfortable with,
and then leave it set at this temperature. You can do this by setting the room thermostat to a low temperature, (for
example 17 °C) and then increasing the setting by one degree each day until you are comfortable with the room
temperature - you won’t have to adjust the thermostat further, as adjustment above this setting will waste energy - a 1
°C increase in temperature is equal to 3% of your heating costs.
MAINTENANCE
The ST620 programmable thermostat requires no special maintenance. Periodically, the outer casing can be wiped clean
using a dry cloth (please DO NOT use solvents, polishes, detergents or abrasive cleaners, as these can damage the thermostat).
There are no user serviceable parts within the unit; any servicing or repairs should only be carried out by Salus Controls
or their appointed agents.
Should the ST620 programmable thermostat fail to function correctly, check:
• The batteries are the correct type, fitted correctly and are not exhausted - fit new batteries if in doubt.
• The ST620 Boiler Control has mains power (LED on)
• Heating system time switch or programmer is switched on.
• If the ST620 is still not functioning correctly, press the Reset Button.
