Pairing with a window sensor means you can switch the heating to Frost Protection if a window opens (in the 10 seconds that follow).

① Press the receiver button for 3 seconds until the red LED flashes.
② Briefly press the detector button.

③ Make sure that the receiver LED has stopped flashing.

7. Pairing with a repeater
If the radio range is too weak and the transmitter cannot be moved closer to the receiver, you can add an X3D radio repeater to your setup (example: ERX 2000).


1 Press the ERX 2000 receiver button for 3 seconds until the red LED flashes. Release the button.
② On the thermostat, press and hold both the mode and + buttons for 3 seconds..
The screen displays rF0x (depending on the number of paired products). Release the button.
③ Press briefly on +. The screen flashes until rF is displayed depending on the number of paired receivers and repeaters (4) (e.g. rF02 for 1 receiver and 1 repeater).
③ Make sure that the repeater LED is no longer flashing.
To exit the mode, briefly tap the mode and + buttons simultaneously.
8. Troubleshooting
8.1 Deleting the pairing of the receiver with the thermostat,
Tydom or window sensor
In the event of a fault, you may have to unpair a product and/or repair a new one.
In the first instance, you should delete the receiver from the transmitter (Thermostat, Tydom, etc) as deletion performed on the receiver will not be synchronised with all transmitters.
Unpairing the receiver from the thermostat









① On the thermostat, press and hold both the mode and + buttons for 3 seconds..
The screen will display rF01.
Release the button.
② Press the button - for 3 seconds until the screen displays rF00. Release the button.
To exit the mode, press the Mode and + buttons simultaneously.
8.2 Removing pairings from the receiver

The deletion of wireless pairings with the receiver is carried out by holding down the button.
The LED will cycle through the various states.
Ⓐ: The LED flashes red. The receiver is in pending pairing mode.
⑧: The red LED is on and steady. The receiver is in LED switch off mode.
©: The red LED flashes rapidly. The receiver is waiting to delete the pairing with a door/window magnetic contact (check on the device you want to be unpaired).
(D) : The red LED turns off. All pairings with the receiver are now removed.
⑤: If you hold down the button for 30 seconds, the LED flashes quickly 3 times.
The receiver is fully reset (back to factory settings).

7. Troubleshooting
7.1 What the receiver LEDs mean
| Signal type Diagnosis/Solutions | |
| The green light is constantly on | Power supply is on. |
| The red light is constantly on | The receiver is requesting heating (pilot wire output = Comfort) |
| The red LED is slowly flashing | The receiver is pending pairing.Please refer to the “Wireless pairing”. chapter |
| The red LED is flashing quickly | The deletion of the pairing between the receiver and a door/window sensor is pending. |
| The green LED is flashing | The receiver isn't paired.Please refer to the "Wireless pairing" chapter. |
| The 2 LEDs are flashing simultaneously | No signal has been received by the thermostat for 1 hour.The receiver is operating in backup mode (*).Turn the thermostat on by pressing a button.If the problem persists, make sure that the transmitter is not too far away and that you have followed the mounting/placement instructions properly. |
| The green LED is flashing slowly | Load-shedding in progress: you are exceeding the consumption allowed in your power subscription. The receiver starts up again automatically after a certain period of time. If an energy manager is also part of the installation, check that is permanently set to Comfort mode. |
| Both LEDs quickly flash simultaneously. | Pilot wire fault.Disconnect the power to the installation and check the cabling or contact your installer. |
