Window Open, AC Off
Stop cooling when the window is open.
A door & window sensor shuts off the AC when a window opens and restores cooling automatically once it closes.
How It Works
- 1
Detects an Open Window
The door & window sensor detects that a window has been opened.
- 2
Turns Off the Air Conditioner Automatically
The air conditioner automatically turns off to avoid cooling or heating the outside air.
- 3
Restores Cooling When the Window Is Closed
Cooling is automatically restored as soon as the window is closed.
Running the air conditioner with a window open wastes a significant amount of energy, cooling or heating outdoor air instead of the guest room. This is a common issue in hotels that rely purely on guest behavior to avoid it.

The door & window sensor detects an open window and turns off the air conditioner automatically. Cooling is restored automatically once the window is closed, with no manual switch needed from housekeeping or engineering staff.
