INTRODUCTION
An RF thermostat is a transmitter that
allows control of a heating system with
no physical connection between the
thermostat and the boiler. This digital
thermostat 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 RT305TX
from Salus Controls is a stylish and accurate digital thermostat with a large,
easy to read Liquid Crystal Display (LCD).
This thermostat can replace most common residential thermostats and is
designed to be used with electric, gas or oil heating control systems. Unlike
ordinary single unit design thermostats, this is a new type of thermostat
separating the operational functions into two units.
The Receiver is used for wiring connections and heat on/off control. The
thermostat provides the user interface and temperature sensing /control.
The two units are linked together by a Radio Frequency (RF) signal.
Features
•Frost protection
•Large, easy to read LCD with blue backlight
•Burner on symbol
•User friendly

INSTALLATION
Please read the important safety information at the start of this manual before
you begin to install the device.
The RT305TX can be used in any convenient
location by using the included stand, or can be easily installed in a fixed
position using the industry standard back plate supplied with the unit –
this is used purely for mounting purposes, as no wiring is needed for the
RT305TX. The back plate can be mounted directly to the wall surface.
The ideal position to locate the RT305TX 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 RT305TX in enclosed areas
such as cellars and basements is not recommended.
AFTER INSTALLATION
The following table shows the settings of the RT305TX digital thermostat
after Power on, or after RESET is pressed:
Function Status After Reset or Power On
Operation Mode Normal mode
Room Temperature 22.0 °C, updated within 5 seconds

USER INTERFACE AND CONTROLS
The status and operation of the RT305TX
is clearly shown on the large backlit Liquid
Crystal Display (LCD). This display allows
the user a clear indication of the current
room temperature, and the status of the
heating system. There are few user
controls for the RT305TX, making this
thermostat very easy to operate. These
controls are shown below, along with a
description of each of their functions.
USER CONTROL FUNCTION SUMMARY
Key / Operation Symbol Functions
UP key Increases the selected setting
DOWN key Decreases the selected setting
BACKLIGHT / Manually turns on the LCD backlight or

OPERATION
The RT305TX is configured and
adjusted by the use of a minimal
number of user controls, and an
intuitive user interface.
The backlit Liquid Crystal Display
(LCD) gives a highly visible, easily
readable indication of the
programmable thermostat status.
REVIEWING SET POINT TEMPERATURE
You can change the set point temperature very
easily while you are reviewing the set point
temperature. Press the UP or DOWN keys
repeatedly to change the temperature setting.
The set point temperature will flash to indicate
that it can be changed:
The temperature will be changed in 0.5°C steps per key press. The
RT305TX will return to Normal mode if no keys are pressed for more than
four seconds. Set point temperature cannot be changed if Frost Protection
mode is enabled.

FROST PROTECTION
To enable the Frost Protection mode, press
and hold the BACKLIGHT / FROST button for
three seconds. Once Frost Protection is
enabled, the set point temperature is
automatically set to 5°C to provide
protection from the risk of freezing.
Whenever Frost Protection is activated, the Frost Protection indicator will
flash in the sequence shown below:
To turn off Frost Protection mode, press and hold the BACKLIGHT / FROST
button for three seconds. Please be aware that the Frost Protection mode
operates as an additional protection feature but should not be used in
place of a correctly installed frost thermostat, which is required to
override all other controls in the system. The backlight will remain
illuminated for approximately 5 seconds.

SETTING UP RF COMMUNICATION WITH
YOUR RECEIVER
RXRT505(ONLY)
After you have switched the above receiver on, the
thermostat will automatically pair. When the red
LED stops flashing, the unit has successfully paired.
If you have difficulty in pairing the thermostat, we
recommend changing the address codes in the
thermostat and the receiver.
To adjust the RF address code of the receiver,
simply push up one or more of the 5 DIP switch
levers on the DIP switch bank located on the back
of the receiver (the levers are numbered 1 to 5
from bottom to top, as shown in the picture left),
and then make a note of the setting of each switch:
To adjust the RF address code of the thermostat,
remove one or more of the jumper caps located on
the back of the unit (labelled 1,2,3,4 and 5, and
shown in the picture left) so that the jumper
settings match the settings made on the receiver:
