INTRODUCTION
A thermostat is a transmitter that is used to switch the
heating system in your home on and off as needed. 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 ST325TX from
SALUS Controls is a stylish and accurate electronic
thermostat with a large, easy to read LCD display. The
thermostat provides the user interface and
temperature sensing / control. The thermostat and
receiver are linked together by a Radio Frequency (RF)
signal. The use of the revolutionary Touch Ring
technology makes for simple usage, and is coupled
with a unique, smart design. The LCD display will
show the current room temperature and the ‘one
touch’ operation makes the ST325TX easy to operate.

•Touch Ring Technology

INSTALLING AND REPLACING BATTERIES
Installing or replacing the ST325TX thermostat batteries is a
straightforward operation, but does require you to open the case
of the thermostat.
To open the ST325TX case, undo the securing screw on the bottom
of the case (just to the right of the hole for the Reset Button):
After undoing the screw pull it forward until the screw stops
moving, then carefully separate the two halves of the case by
gently pulling in an upwards direction. Once the case has been
separated, the batteries should be visible:
Ensure that the batteries are inserted correctly, paying careful
attention to the polarity markings on the battery and next to the
battery holders. After inserting the batteries, refit the ST325TX case
and retighten the securing screw.
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 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.
To ensure trouble free operation of the Radio Frequency (RF) signal, always ensure that the
programmable thermostat is mounted away from any possible sources of interference (such
as radios, TV sets, computers, etc.), and is not mounted on or in close proximity to large metal
objects. Installing the ST325TX in enclosed areas such as cellars and basements is not
recommended.

ON THE THERMOSTAT:
The Arrow key is not active when the ST325TX is in NORMAL
mode. To access the Menu screens, press the OK key once.
The first menu displayed is the FROST menu:
Use the Touch Ring to scroll through the Menus,
and press the OK key to select the PAIR menu:
You can scroll through the menus in either direction (forwards or backwards) depending
on the direction you move your finger around the Touch Ring. The menus are displayed
in the order shown in the picture above.

ST325TX Manual Version BLUE_Layout 1 12/03/2014 14:27 Page 6
After selecting the PAIR Menu,
PAIR and the RF icon are displayed.
Press the OK key to start sending the RF address
code to the receiver. The ST325TX thermostat
display will change to show a rundown timer:
The unit counts down for a period of 10 minutes, with the RF Signal
indicator flashing while the signal is being transmitted. The RF
address code will be generated randomly and the thermostat will
transmit the signal every second for the full 10 minutes until:
•The Arrow key is pressed to return to the previous display
•The OK key is pressed to return to NORMAL mode
•The 10 minute timer runs out
Note that the receiver must be already in learning mode BEFORE attempting to access the
PAIR menu on the thermostat. If the Red SYNC LED has not turned off after 10 minutes,
repeat the whole pairing process.

ST325TX Manual Version BLUE_Layout 1 12/03/2014 14:27 Page 7
Pressing the reset button on the thermostat and the receiver (RXST625 only) will clear the
RF address code and generate a new default code which will be saved into the internal
memory of the unit; there is no need to re-pair the receiver and thermostat. This is a quick
and easy way to directly link the units in many applications.
Replacing the thermostat batteries will not affect the RF code setting. Pressing and holding
the SYNC button on the receiver will however clear the RF address code saved into the
internal memory, and switch the receiver into learning mode, as previously described.
AFTER INSTALLATION
After completing installation and powering up the ST325TX for the first
time the programmable thermostat will behave in the following way:
All the indicators on the display and the backlight will be turned on.
After two seconds, the display will change to show the currently
installed firmware version.
The ST325TX will then operate in NORMAL mode and display the
current room temperature.
All programmable thermostat settings will have been returned to
default values.
If the Reset Button is pressed, the ST325TX will behave in the same way
as described above, except that any previously saved user settings
stored in the internal memory will be deleted and overwritten with the
default settings.

ST325TX Manual Version BLUE_Layout 1 12/03/2014 14:27 Page 9
OPERATION
The ST325TX 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 ST325TX 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.
If the ST325TXRF 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
ST325TXRF to NORMAL mode.
