THE INSTALLATION GUIDE
INTRODUCTION
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 serves for wiring connections and
heat on/off control. The Control Centre serves as user
interface and temperature sensing/control. The two units are
linked by Radio Frequency.
The RT300RF is easily installedusing the Industry Standard
back plate supplied (for mounting purposes only as no
wiring is required when installing the control centre).
The back plate can be mounted directly to the wall surface.

Thank you for purchasing this Salus product
- if installing for someone else, please ensure that
the instructions are handed to the householder.
Warning - Please read this manual prior to
installation or use.
Shock Hazard
This unit must be installed by a competent person,
in accordance with BS 7671 (the IEE Wiring
Regulations), or other relevant national regulations
and codes of good practice.
Always isolate the AC Mains supply before
installing this unit.
Jumpers Function
Span 1 moveable Jumper for selecting
temperature span of +/-0.5°C
(factory default setting) or 1.0°C
1,2,3,4,5 5 removable Jumpers for altering the
RF address code when used in
conjunction with the receivers
corresponding dip switch.
SWITCHES/JUMPERS:
The installer should select the jumper positions required if
changing from the factory presets. These jumpers are found
on the rear of the unit.
TESTING THE RF TRANSMISSION
It is important to site the Receiver and Control Centre in
locations where the RF signal cannot be interrupted. The
receiving range between Control Centre and Receiver is
60M in open area. Many factors can affect the RF
transmission, shortening the operating distance e.g.
shielding by thick walls, foil back plasterboard, metal
objects such as filing cabinets, general RF interference
etc, However, the range is enough for most household
applications.
It is advisable to test the RF transmission from the
intended Control Centre location to the Receiver location
before fixing the Control Centre to the wall.
1. Press UP button until the set-point temperature is higher
than room temperature by a few degrees.
2. Wait for a few seconds. The animated flame (heat call
indicator) shouldappear on the bottom left of the LCD on
the control centre.
3. Check the green LED on the receiver unit. It should be
illuminated.
4. Press Down button to adjust the set-point temperature to
be lower than room temperature. Wait for a few seconds.
The animated flame (heat call indicator) should disappear
and the green LED should switch off
5. If at step 3 the green LED is not illuminated, press DOWN
button to adjust the required temperature to lower than
the current room temperature to stop the unit calling for
heat. Try to place the Control Centre closer to the
Receiver, repeating steps 1 to 4.
6. Alternatively you can try and alter the address code
following the ‘RF Address Code Setting’ section of this
manual, then repeat steps 1 to 4.
Note that the RESET button on the Control Centre should be
pressed after altering the address code.
1) Remember to Isolate AC mains supply, note this
must be 230V AC and fused at 13 amps max.
2) Select a suitable indoor location free from water and
moisture.
3) The receiver should not be shielded from the RF signal in
any way, follow ‘Testing the RF Transmission’ section of
this manual before deciding on a final location for the
receiver and control centre units.
4) To access the wiring terminals carefully prize off the front
cover from the top middle of the receiver with a flat head
screw driver and remove the 2 screws underneath as
illustrated in the diagram.
Receiver On/Off switch and LED’s
On removing the front cover you will note there is an On/Off
switch and 2 LED’s. The switch allows you to turn off the
Receiver if necessary to prevent it calling for heat. The left LED
illuminates red when the switch is in On position and the unit
is receiving power. The other LED illuminates green when the
receiver unit is calling for heat upon receiving a heat call
transmission from the Control Centre.
WIRING THE RECEIVER FOR THE RT300RF
RF ADDRESS CODE SETTING
If there is another user nearby, e.g. in the next house or if
you are installing more than 1 unit your receiver may be
triggered by the wrong transmitter. You may select a
different RF address code to prevent this. The receiver can
only respond to RF transmissions with the same address
code setting as its own address code.
Address Code Dip
Switch Leavers.
1. To adjust address code of Receiver, simply
push up one or more of the 5 dip switch levers.
The leavers are numbered 1 to 5 from left to right.
2. To adjust address code of Control Centre, remove
one or more of the jumper caps located on the
back of the unit, labeled 1,2,3,4,5.
3. You must press reset on the control centre after
altering the address code.
Caution :
1. Address code of Control Centre must be the same as
address code of Receiver. For any address code jumper
cap removal in the Control Centre, the corresponding
address code dip switch leaver in the Receiver must be
put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.
INITIAL POWER UP:
• On installation supplied batteries or if RESET is pressed,
the thermostat is reset.
• During system reset, all LCD segments are turnedon for
2 seconds. After 2 seconds the thermostat is initialised
and displays a default room temperature of 22˚C to be
renewed within 5 seconds.

MULTIPLE THERMOSTAT
INSTALLATIONS
Please note, if using more than one RT300RF in
the same installation, be sure that there is at
least a 1 metre gap between receiver units to
avoid RF interference.
When installing multiple thermostats you should ensure that you
assign different address codes for each RT300RF following the ‘RF
Address Code Setting’ section of this manual. Each RT300RF should
be introduced to the installation one at a time with all other
receiver units switched off, also make sure that the batteries are
removed from all other Control Centres.
Install each unit following the ‘TESTING THE RF TRANSMISSION’
section of this manual. Once you are happy with the operation of
one unit you may install the next. Once all RT300RFs are installed,
if one unit then seems to function abnormally, try changing the
address code of the control centre & its corresponding receiver
again taking care that the new code given is different to all others
in the installation.
The control centre sends RF On/Off signals every 10 min to ensure
the receiver is in the correct state. If for some reason the 1st RF
signal is interrupted you may notice the control centre has
started/stopped calling for heat but the receiver hasn’t switched.
Simply wait 10 minutes until the next RF signal is transmitted and
the receiver unit should switch.

MULTIPLE THERMOSTAT
INSTALLATIONS
Please note, if using more than one RT300RF in
the same installation, be sure that there is at
least a 1 metre gap between receiver units to
avoid RF interference.
When installing multiple thermostats you should ensure that you
assign different address codes for each RT300RF following the ‘RF
Address Code Setting’ section of this manual. Each RT300RF should
be introduced to the installation one at a time with all other
receiver units switched off, also make sure that the batteries are
removed from all other Control Centres.
Install each unit following the ‘TESTING THE RF TRANSMISSION’
section of this manual. Once you are happy with the operation of
one unit you may install the next. Once all RT300RFs are installed,
if one unit then seems to function abnormally, try changing the
address code of the control centre & its corresponding receiver
again taking care that the new code given is different to all others
in the installation.
The control centre sends RF On/Off signals every 10 min to ensure
the receiver is in the correct state. If for some reason the 1st RF
signal is interrupted you may notice the control centre has
started/stopped calling for heat but the receiver hasn’t switched.
Simply wait 10 minutes until the next RF signal is transmitted and
the receiver unit should switch.

THE INSTALLATION GUIDE
INTRODUCTION
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 serves for wiring connections and
heat on/off control. The Control Centre serves as user
interface and temperature sensing/control. The two units are
linked by Radio Frequency.
The RT300RF is easily installed using the Industry Standard
back plate supplied (for mounting purposes only as no
wiring is required when installing the control centre).
The back plate can be mounted directly to the wall surface.

Thank you for purchasing this Salus product
- if installing for someone else, please ensure that
the instructions are handed to the householder.
Warning - Please read this manual prior to
installation or use.
Shock Hazard
This unit must be installed by a competent person,
in accordance with BS 7671 (the IEE Wiring
Regulations), or other relevant national regulations
and codes of good practice.
Always isolate the AC Mains supply before
installing this unit.
Jumpers Function
Span 1 moveable Jumper for selecting
temperature span of +/-0.5°C
(factory default setting) or 1.0°C
1,2,3,4,5 5 removable Jumpers for altering the
RF address code when used in
conjunction with the receivers
corresponding dip switch.
SWITCHES/JUMPERS:
The installer should select the jumper positions required if
changing from the factory presets. These jumpers are found
on the rear of the unit.
TESTING THE RF TRANSMISSION
It is important to site the Receiver and Control Centre in
locations where the RF signal cannot be interrupted. The
receiving range between Control Centre and Receiver is
60M in open area. Many factors can affect the RF
transmission, shortening the operating distance e.g.
shielding by thick walls, foil back plasterboard, metal
objects such as filing cabinets, general RF interference
etc, However, the range is enough for most household
applications.
It is advisable to test the RF transmission from the
intended Control Centre location to the Receiver location
before fixing the Control Centre to the wall.
1. Press UP button until the set-point temperature is higher
than room temperature by a few degrees.
2. Wait for a few seconds. The animated flame (heat call
indicator) shouldappear on the bottom left of the LCD on
the control centre.
3. Check the green LED on the receiver unit. It should be
illuminated.
4. Press Down button to adjust the set-point temperature to
be lower than room temperature. Wait for a few seconds.
The animated flame (heat call indicator) should disappear
and the green LED should switch off
5. If at step 3 the green LED is not illuminated, press DOWN
button to adjust the required temperature to lower than
the current room temperature to stop the unit calling for
heat. Try to place the Control Centre closer to the
Receiver, repeating steps 1 to 4.
6. Alternatively you can try and alter the address code
following the ‘RF Address Code Setting’ section of this
manual, then repeat steps 1 to 4.
Note that the RESET button on the Control Centre should be
pressed after altering the address code.
1) Remember to Isolate AC mains supply, note this
must be 230V AC and fused at 13 amps max.
2) Select a suitable indoor location free from water and
moisture.
3) The receiver should not be shielded from the RF signal in
any way, follow ‘Testing the RF Transmission’ section of
this manual before deciding on a final location for the
receiver and control centre units.
4) To access the wiring terminals carefully prize off the front
cover from the top middle of the receiver with a flat head
screw driver and remove the 2 screws underneath as
illustrated in the diagram.
Receiver On/Off switch and LED’s
On removing the front cover you will note there is an On/Off
switch and 2 LED’s. The switch allows you to turn off the
Receiver if necessary to prevent it calling for heat. The left LED
illuminates red when the switch is in On position and the unit
is receiving power. The other LED illuminates green when the
receiver unit is calling for heat upon receiving a heat call
transmission from the Control Centre.
WIRING THE RECEIVER FOR THE RT300RF
RF ADDRESS CODE SETTING
If there is another user nearby, e.g. in the next house or if
you are installing more than 1 unit your receiver may be
triggered by the wrong transmitter. You may select a
different RF address code to prevent this. The receiver can
only respond to RF transmissions with the same address
code setting as its own address code.
Address Code Dip
Switch Leavers.
1. To adjust address code of Receiver, simply
push up one or more of the 5 dip switch levers.
The leavers are numbered 1 to 5 from left to right.
2. To adjust address code of Control Centre, remove
one or more of the jumper caps located on the
back of the unit, labeled 1,2,3,4,5.
3. You must press reset on the control centre after
altering the address code.
Caution :
1. Address code of Control Centre must be the same as
address code of Receiver. For any address code jumper
cap removal in the Control Centre, the corresponding
address code dip switch leaver in the Receiver must be
put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.

THE INSTALLATION GUIDE
INTRODUCTION
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 serves for wiring connections and
heat on/off control. The Control Centre serves as user
interface and temperature sensing/control. The two units are
linked by Radio Frequency.
The RT300RF is easily installed using the Industry Standard
back plate supplied (for mounting purposes only as no
wiring is required when installing the control centre).
The back plate can be mounted directly to the wall surface.

Thank you for purchasing this Salus product
- if installing for someone else, please ensure that
the instructions are handed to the householder.
Warning - Please read this manual prior to
installation or use.
Shock Hazard
This unit must be installed by a competent person,
in accordance with BS 7671 (the IEE Wiring
Regulations), or other relevant national regulations
and codes of good practice.
Always isolate the AC Mains supply before
installing this unit.
Jumpers Function
Span 1 moveable Jumper for selecting
temperature span of +/-0.5°C
(factory default setting) or 1.0°C
1,2,3,4,5 5 removable Jumpers for altering the
RF address code when used in
conjunction with the receivers
corresponding dip switch.
SWITCHES/JUMPERS:
The installer should select the jumper positions required if
changing from the factory presets. These jumpers are found
on the rear of the unit.
TESTING THE RF TRANSMISSION
It is important to site the Receiver and Control Centre in
locations where the RF signal cannot be interrupted. The
receiving range between Control Centre and Receiver is
60M in open area. Many factors can affect the RF
transmission, shortening the operating distance e.g.
shielding by thick walls, foil back plasterboard, metal
objects such as filing cabinets, general RF interference
etc, However, the range is enough for most household
applications.
It is advisable to test the RF transmission from the
intended Control Centre location to the Receiver location
before fixing the Control Centre to the wall.
1. Press UP button until the set-point temperature is higher
than room temperature by a few degrees.
2. Wait for a few seconds. The animated flame (heat call
indicator) shouldappear on the bottom left of the LCD on
the control centre.
3. Check the green LED on the receiver unit. It should be
illuminated.
4. Press Down button to adjust the set-point temperature to
be lower than room temperature. Wait for a few seconds.
The animated flame (heat call indicator) should disappear
and the green LED should switch off
5. If at step 3 the green LED is not illuminated, press DOWN
button to adjust the required temperature to lower than
the current room temperature to stop the unit calling for
heat. Try to place the Control Centre closer to the
Receiver, repeating steps 1 to 4.
6. Alternatively you can try and alter the address code
following the ‘RF Address Code Setting’ section of this
manual, then repeat steps 1 to 4.
Note that the RESET button on the Control Centre should be
pressed after altering the address code.
1) Remember to Isolate AC mains supply, note this
must be 230V AC and fused at 13 amps max.
2) Select a suitable indoor location free from water and
moisture.
3) The receiver should not be shielded from the RF signal in
any way, follow ‘Testing the RF Transmission’ section of
this manual before deciding on a final location for the
receiver and control centre units.
4) To access the wiring terminals carefully prize off the front
cover from the top middle of the receiver with a flat head
screw driver and remove the 2 screws underneath as
illustrated in the diagram.
Receiver On/Off switch and LED’s
On removing the front cover you will note there is an On/Off
switch and 2 LED’s. The switch allows you to turn off the
Receiver if necessary to prevent it calling for heat. The left LED
illuminates red when the switch is in On position and the unit
is receiving power. The other LED illuminates green when the
receiver unit is calling for heat upon receiving a heat call
transmission from the Control Centre.
WIRING THE RECEIVER FOR THE RT300RF
RF ADDRESS CODE SETTING
If there is another user nearby, e.g. in the next house or if
you are installing more than 1 unit your receiver may be
triggered by the wrong transmitter. You may select a
different RF address code to prevent this. The receiver can
only respond to RF transmissions with the same address
code setting as its own address code.
Address Code Dip
Switch Leavers.
1. To adjust address code of Receiver, simply
push up one or more of the 5 dip switch levers.
The leavers are numbered 1 to 5 from left to right.
2. To adjust address code of Control Centre, remove
one or more of the jumper caps located on the
back of the unit, labeled 1,2,3,4,5.
3. You must press reset on the control centre after
altering the address code.
Caution :
1. Address code of Control Centre must be the same as
address code of Receiver. For any address code jumper
cap removal in the Control Centre, the corresponding
address code dip switch leaver in the Receiver must be
put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.
INITIAL POWER UP:
• On installation supplied batteries or if RESET is pressed,
the thermostat is reset.
• During system reset, all LCD segments are turned on for
2 seconds. After 2 seconds the thermostat is initialised
and displays a default room temperature of 22˚C to be
renewed within 5 seconds.

MULTIPLE THERMOSTAT
INSTALLATIONS
Please note, if using more than one RT300RF in
the same installation, be sure that there is at
least a 1 metre gap between receiver units to
avoid RF interference.
When installing multiple thermostats you should ensure that you
assign different address codes for each RT300RF following the ‘RF
Address Code Setting’ section of this manual. Each RT300RF should
be introduced to the installation one at a time with all other
receiver units switched off, also make sure that the batteries are
removed from all other Control Centres.
Install each unit following the ‘TESTING THE RF TRANSMISSION’
section of this manual. Once you are happy with the operation of
one unit you may install the next. Once all RT300RFs are installed,
if one unit then seems to function abnormally, try changing the
address code of the control centre & its corresponding receiver
again taking care that the new code given is different to all others
in the installation.
The control centre sends RF On/Off signals every 10 min to ensure
the receiver is in the correct state. If for some reason the 1st RF
signal is interrupted you may notice the control centre has
started/stopped calling for heat but the receiver hasn’t switched.
Simply wait 10 minutes until the next RF signal is transmitted and
the receiver unit should switch.

Receiver if necessary to prevent it calling for heat. The left LED
illuminates red when the switch is in On position and the unit
is receiving power. The other LED illuminates green when the
receiver unit is calling for heat upon receiving a heat call
transmission from the Control Centre.
WIRING THE RECEIVER FOR THE RT300RF
RF ADDRESS CODE SETTING
If there is another user nearby, e.g. in the next house or if
you are installing more than 1 unit your receiver may be
triggered by the wrong transmitter. You may select a
different RF address code to prevent this. The receiver can
only respond to RF transmissions with the same address
code setting as its own address code.
Address Code Dip
Switch Leavers.
1. To adjust address code of Receiver, simply
push up one or more of the 5 dip switch levers.
The leavers are numbered 1 to 5 from left to right.
2. To adjust address code of Control Centre, remove
one or more of the jumper caps located on the
back of the unit, labeled 1,2,3,4,5.
3. You must press reset on the control centre after
altering the address code.
Caution :
1. Address code of Control Centre must be the same as
address code of Receiver. For any address code jumper
cap removal in the Control Centre, the corresponding
address code dip switch leaver in the Receiver must be
put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.
INITIAL POWER UP:
• On installation supplied batteries or if RESET is pressed,
the thermostat is reset.
• During system reset, all LCD segments are turned on for
2 seconds. After 2 seconds the thermostat is initialised
and displays a default room temperature of 22˚C to be
renewed within 5 seconds.

It is vital to connect the live
into this terminal to avoid
overloading of the jump
wire.
MULTIPLE THERMOSTAT
INSTALLATIONS
Please note, if using more than one RT300RF in
the same installation, be sure that there is at
least a 1 metre gap between receiver units to
avoid RF interference.
When installing multiple thermostats you should ensure that you
assign different address codes for each RT300RF following the ‘RF
Address Code Setting’ section of this manual. Each RT300RF should
be introduced to the installation one at a time with all other
receiver units switched off, also make sure that the batteries are
removed from all other Control Centres.
Install each unit following the ‘TESTING THE RF TRANSMISSION’
section of this manual. Once you are happy with the operation of
one unit you may install the next. Once all RT300RFs are installed,
if one unit then seems to function abnormally, try changing the
address code of the control centre & its corresponding receiver
again taking care that the new code given is different to all others
in the installation.
The control centre sends RF On/Off signals every 10 min to ensure
the receiver is in the correct state. If for some reason the 1st RF
signal is interrupted you may notice the control centre has
started/stopped calling for heat but the receiver hasn’t switched.
Simply wait 10 minutes until the next RF signal is transmitted and
the receiver unit should switch.
WIRING INTO THE EXTERNAL
THERMOSTAT LOOP OF A BOILER

SETTING SETPOINT TEMPERATURE:
•
Whilst reviewing the setpoint temperature, press or
repeatedly to change the setting, raising or lowering the
temperature by 0.5˚C per press. The Setpoint
temperature is flashing to
indicate that it can
be changed.
• Holding or for 2 seconds will fast advance the
temperature by 2˚C per second.
• Thermostat will return to normal mode after 3-4 seconds if
no key is pressed.
When Frost Protection is enabled, setting of Setpoint
temperature is prohibited.
REVIEWING SETPOINT TEMPERATURE:
• Press or once, to review the Setpoint
temperature.
• Press BL/FROST or simply
wait 3 seconds without key
press to return to normal
operation, the current
room temperature will be
displayed again.
FROST PROTECTION:
• Press and hold BL/FROST for 3 seconds to
activate Frost Protection.
The Setpoint temperature is automatically set to 5°C to
prevent frosting.
The RT300RF will now only
call for heat if the temperature
drops below 5°C
• Whenever the Frost Protection is activated, the
Frost Protection indicator will animate in the lower
left corner of the LCD with the below sequence.
• Press BL/FROST for 3 seconds to de-activate the
Frost Protection, the Frost Protection indicator is
