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:

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:

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.
