It works by sensing the air temperature and switching on the heating when the air temperature falls below the thermostat setting, and switching it off once the set temperature has been reached. The ST320 from Salus Controls is a stylish and accurate electronic thermostat with a large, easy to read LCD display.
Please read the important safety information at the start of this manual before you start to install the device. The ideal position to locate the ST320 thermostat is about 1.5m above floor level. It should be mounted in a location where the thermostat is accessible, reasonably lit and free from extremes of temperature and draughts.
Battery Status Indicates battery is low There are few user controls for the ST320, making the thermostat very easy to operate. The controls are a Touch Ring (which surrounds the user display), two touch sensitive buttons, a reset button and a slide operated switch mounted on the side of the thermostat.
