USER INTERFACE AND CONTROLS
The status and operation of the ST320 is clearly
shown on the large backlit Liquid Crystal Display (LCD).
The display consists of a combination of symbols and alphanumeric displays. The top row is a set of
status symbols, the centre row is used to indicate temperature (in Celsius), and the bottom row is
an alphanumeric display for menu and status messages.
The status symbol functions are:
Indicator Description Function
RF Signal indicator
(Not used with ST320) Indicates the unit is transmitting a wireless signal
Touch Lock indicator Indicates touch lock is activated
Heat Mode indicator Indicates heating output is turned on.
Frost Mode indicator Indicates frost setting is turned on
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.
These controls are shown below, along with a description of each of their functions.
