To directly control a LightwaveRF TRV, Thermostat or 
Electric Switch using a Magnetic Trigger, you will need to 
‘link’ them. The trigger can be linked to these devices 
using the following method: 

1.

 Press and release the ‘Linking’ button on the Magnetic 

Trigger (the LED will flash). 

2. 

Press and release the Linking button on the TRV, 

Electric Switch or Thermostat that you wish to link to. 
The ‘on’ LED should flash to indicate a successful link.

Note:

 linking mode lasts for 12 seconds; if no linking 

command is received within this time, then linking mode 
will time out and the process will have to be re-initiated. 

To completely clear the memory of the Switch and unlink 
any linked devices, press and release the Linking button to 
enter linking mode (the LEDs will flash). Then, hold the 
Linking button until the LEDs flash rapidly. Finally, press and 
release the Linking button once more. The LED will flash 
more slowly to confirm that the memory has been cleared.
