(Wintop) Installing Your 3-Way Sensor
You'll probably want to permanently mount your 3-way sensor in an appropriate location in your home. For optimal results, mount it between six and ten feet from the floor along an indoor wall where it is not obstructed by an adjacent wall, as shown below.
NOTE: The 3-way sensor should not be mounted outdoors, or where it might be splashed with water.
To mount the 3-way sensor, remove the battery cover, screw the included ball-mount joint into one of the provided mounting holes, and then replace the cover. You can now attach the mount to any appropriate wall, using the supplied hardware.
