RT RECEIVER
INTRODUCTION
The RXRT505 is used for the wiring connections and on/off
control. The RXRT505 is linked to your thermostat via radio
frequency (RF) signal.
Features
• LED status indication
• ON / OFF switch
• 868 MHz communication
CONNECTING THE RXRT505 RECEIVER
The RT Receiver should be mounted in a suitable location that is
both accessible for the connection of mains and control wiring,
and allows good reception of the RF signal. The receiver needs a
230V AC mains supply to operate, and this should be fused
appropriately (13A max.). The receiver should be mounted in a
location where it will not come into contact with water, moisture
or condensation.
The receiver On/Off switch is accessible from the front face of the
receiver, as shown in this picture:
RXRT505 INSTRUCTION MANUAL 5

On the front cover of the receiver you will
see that there is the On/Off switch and two
Light Emitting diodes (LEDs). The switch
allows you to turn off the receiver if
necessary to prevent it calling for heat. The
top LED (red) will illuminate when the
switch is in the ‘On’ position and the unit is
receiving power. The top LED (green)
illuminates when the receiver is
receiving a heat call transmission from the
thermostat. The wiring terminals and RF Address Code setting DIP switches
are located on the rear of the receiver, as shown above:
RECEIVER WIRING TERMINALS
Terminal Identifier Description
1 NO Normally Open (N/O) Volt free contacts
2 COM Common terminal (COM) Volt free contacts
3 L Live supply (230V AC)
4 N Neutral
TYPICAL WIRING INSTALLATIONS
The RT receiver is wired the same
way no matter if you are wirings
230V or 24V, the receiver will
always need a 230V Live and
Neutral feed connected into L &
N terminals. The COM and NO is
to be connected to the boilers
external loop (see diagram
below), if connected in this way
the receiver relay can only switch
voltage supplied by the boiler.

SETTING UP RF COMMUNICATION WITH
YOUR THERMOSTAT
RT505TX / RT305TX
After you have switched the receiver on, the
thermostat will automatically pair* with the
RT505TX and the RT305TX (only). 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:

Thermostat
Jumper Caps
ST325TX / ST625TX
1. Switch power on the receiver, the receiver
will now automatically enter pairing mode.
2. Enter Pair Menu on the S-Series thermostat
and start the pairing procedure*.
3. When the red LED on the receiver stops
flashing, pairing has been successful.

S-SERIES RECEIVERS
INTRODUCTION
The RXST625 is used for the wiring connections and on/off
control. The RXST625 is linked to your thermostat via radio
frequency (RF) signal.
Features
• LED status indication
• Manual override
• 868 MHz communication
CONNECTING THE RXST625 RECEIVER
The RT receiver should be mounted in a suitable location that is
both accessible for the connection of mains and control wiring,
and allows good reception of the RF signal. The receiver needs a
230V AC mains supply to operate, and this should be fused
appropriately (13A max.). The receiver should be mounted in a
location where it will not come into contact with water, moisture
or condensation.

TYPICAL WIRING INSTALLATIONS
The RXST625 receiver is wired the
same way no matter if you are
wirings 240V or 24V, the receiver
will always need a 240V Live and
Neutral feed connected into L & N
terminals. The COM and NO is to
be connected to the boilers
External Loop (see diagram
below), if connected in this way
the receiver relay can only switch
voltage supplied by the boiler.
SETTING UP RF COMMUNICATION:
Ensure that the slide switches are in AUTO and ON positions and then press
the sync button. Press and hold the SYNC button for at least 3 seconds,
then release. The receiver will now enter pairing mode, the green LED will
now turn red to indicate that the receiver is ready to pair with the
thermostat*.
While the signal is being received, the red LED will stay on until the pairing
is successful, when pairing is successfull the red LED will turn green.

RECEIVER LED INDICATORS
The LED indicators on the RXST625 receiver are designed to give a clear
and easily understood indication of the current state of the system. The
various LED signal combinations and descriptions of what they indicate
are shown in the table below:
LED State Indication
Blue On Receiver is in manual mode and system is calling for heat.

Red On and Receiver is either receiving a new RF address code in SYNC mode,
flashing or has failed to store the new RF address code when in SYNC mode
Yellow On Receiver is in failsafe mode after no RF signal received for over 1 hour
RXST625 INSTRUCTION MANUAL

The status of the RXST625 receiver is indicated by the use of two bi-
colour Light Emitting Diodes (LEDs). The status indicators are:
USER CONTROL FUNCTION SUMMARY
Key/Operation Functions
Auto Sets receiver to Automatic mode (default setting)
Manual Sets receiver to Manual mode
On Turns relay output ON (default setting)
Cycle Switches receiver output on and off in a 15 minute cycle
(4 minutes on, 11 minutes off)
Off Turns relay output OFF
SYNC Button Enables RF signal synchronisation with RXST625 thermostat
Reset Button Resets the receiver to default (original factory) settings
RECEIVER MODES
The RF receiver can operate in three different modes – AUTO or
MANUAL, and also has a FAILSAFE mode of operation. These modes are
selected by using the slide switches on the front of the receiver:
AUTO MODE
Moving the slide switch to the ‘AUTO’ position selects the Automatic
operation mode of the RF receiver In this mode, the receiver will
automatically receive an RF signal from the thermostat and control the
output relay. When in auto mode, if RF communication between the
receiver and thermostat is lost for less than one hour, the receiver
remains in the same operating state it was in when the signal was lost.
If the RF signal is lost for more than one hour, the receiver will enter
Failsafe mode, and control of the receiver output will be based on the
setting of the Failsafe mode switch. Please be aware that if the
thermostat is operating in Service mode when changing the receiver
switch position, the relay output may be affected.
RXST625 INSTRUCTION MANUAL 11

MANUAL MODE
Moving the slide switch to the ‘MANUAL’ position selects the manual
operation mode of the RF receiver. In manual mode, the receiver
ignores the RF signal from the thermostat and controls the output relay
manually, based on the setting of the failsafe mode switch.
FAILSAFE MODES
Failsafe mode has three user selectable settings – ‘ON’, ‘CYCLE’ and
‘OFF’. With the failsafe switch in the ON position, the output relay will
be turned on, in the OFF position the output relay will be turned off,
and in the CYCLE position the output relay will be operated according
to a preset time sequence (on for 4 minutes and off for 11 minutes).
When operating in failsafe mode, the LEDs will indicate the receiver
relay status as follows:
Mode LEDs Indication
On Blue and Yellow Each LED lights alternately,
approx. once per second
Off Yellow On
Cycle Blue On for 4 minutes,
off for 11 minutes
If required the user can switch to another mode without having to reset
the controller; for instance you can switch from auto mode to manual
mode with the output relay being controlled accordingly. To illustrate
this point, even when switched into manual mode the receiver can still
receive the RF signal from the thermostat and once the user switches to
auto mode, the output relay will be controlled to turn on or turn off
automatically once more.

RF Transmission
The receiving range between your thermostat and the RF Boiler
Control is around 100 metres in open air, however many factors
can affect the RF transmission and shorten the operating
distance, e.g. shielding by thick walls, foil back plasterboard,
metal objects such as filing cabinets, general RF interference,
and so on. The operating range is generally around 30 metres,
which is large enough for most household applications.
