Location Considerations; Fan Mode Switch Installation; Wired Zone Sensor Installation - Trane UniTrane Installation, Operation And Maintenance Instructions

Height Requirements
It is recommended that you mount the back plate a maximum distance of 54 inches above the floor.
If a parallel approach by a person in a wheelchair is required, reduce the maximum height to
48 inches.
Note: Consult section 4.27.3 of the 2002 ADA (Americans with Disability Act) guideline, and local
Mounting Surfaces
Using the hardware provided, mount the back plate of the sensor to a flat surface such as sheetrock
or plaster, or an electrical junction box. The sensor must be mounted plumb for accurate
