Reduce heat loss
101 ways to use LightwaveRF
No. 4 Reduce heat loss from windows
A lot of energy can be wasted when windows are left open in a heated room. When attached to a window frame, a LightwaveRF Magnetic Trigger can automatically instruct a LightwaveRF radiator valve to turn down the radiator temperature when it detects an open window. It will then automatically restore the temperature when the window is closed.
