How to use the Magnetic Trigger
Each LightwaveRF Magnetic Trigger can be used to turn on and off a
LightwaveRF TRV, Electric Switch or Thermostat if a window or door is
opened or closed.
The trigger will automatically setback a TRV, an Electric Switch or
Thermostat (default of 11 degrees) if a window is opened and return them to
their previous set temperature when the window is closed again. The trigger
will interupt any set schedule for the LightwaveRF heating device if
activated, but return to the schedule once closed.
