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

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:

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.
