NOTE: Select a location for the master which has an ambient
temperature range of 50 to 90°F. Do not mount the master in
the attic or unheated space.
Determine the location of the master unit. When positioning
cables to exit the wall cavity, all cables must exit at the same
height on the wall stud. The group of cables can exit at any
height above 18"; however, NuTone recommends the cables
exit at 60".
Expose a minimum of 24" of each cable from the wall cavity
into the room to alert drywall installer to route through drywall.
For your convenience, it is recommended that each

connected accessory (for example "S-143/Front Door
Pushbutton").
