MAINTENANCE
The ST320 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 ST320 thermostat fail to function correctly, check:
• Thermostat batteries are the correct type, fitted correctly and are not exhausted -
fit new batteries if in doubt.

• If the ST320 is still not functioning correctly, press the Reset Button.
