If the ST320 is operating in Frost Mode the LCD will display both the room temperature and also the
Frost Mode indicator . To turn off FROST mode, select the FROST menu and then by using the Touch
Ring scroll to the OFF setting. OFF will then be displayed on the LCD.
After pressing the Touch Ring, the LCD will display the preset Frost Mode
temperature of 5 ºC (this temperature is factory set and cannot be adjusted).
Pressing the OK or Arrow keys will return the ST320 to NORMAL mode.
CHANGING THE SET TEMPERATURE
When the ST320 is in NORMAL mode, press the Touch Ring anywhere
except the OK and Arrow keys (as described in the previous section), to
enter the Review Set Temperature mode. The currently set temperature
will be displayed on the LCD and will flash.
When the set temperature is flashing, press the Touch Ring and move your finger clockwise to
increase the set temperature, or anti-clockwise to decrease the set temperature. Press OK at any time
to confirm the selection. Note that the set temperature display will not flash while being adjusted –
this is normal and the display will start to flash again approximately 0.5 seconds after the Touch
Ring is released.
The ST320 will go back to NORMAL mode without changing the set temperature after 10 seconds of
inactivity, or after pressing the Arrow key.
If the ST320 is in FROST mode, the set temperature cannot be adjusted. Turn off FROST mode
as described below to allow the set temperature to be changed.
