INSTALLATION
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. Do not mount the thermostat on an outside wall, above a radiator or in
a location where it may be subjected to direct sunlight.
There are only two electrical connections required to the
ST320, and these connections should be made to the
terminal block inside the thermostat. No Earth
connection is required for the correct and safe operation
of the ST320, but a parking terminal is provided to
connect an Earth wire if one is present. These connections
are shown in the drawing and table below:
Terminal Function

engineer or your boiler / heating system supplier for advice on how to continue.

OPERATION
The ST320 is configured and adjusted by the use of
an innovative and stylish Touch Ring, and two touch
sensitive buttons. The Touch Ring surrounds the
thermostat display, and is operated very easily by
moving your finger around the ring.
The backlit Liquid Crystal Display (LCD) gives a highly visible, easily readable indication of the
thermostat status.
REVIEWING THE SET TEMPERATURE
If you press the Touch Ring anywhere except the OK and Arrow keys when the
ST320 is in NORMAL mode (NORMAL mode is when the thermostat is
displaying the room temperature), you can check the set temperature setting.
This will display the current set temperature. The set temperature will be displayed for two seconds
before the LCD changes to display the room temperature again.

Salus ST320 Manual New.qxd:Layout 1 19/5/10 09:21 Page 8
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.
