Base Module - PTAC Installation
Range between the thermostat and the base module is up to 100 feet
with no obstructions and up to 50 feet through standard building
materials. To optimize the range try placing the base module with no
metal between it and the thermostat.
The base module is designed to be mounted behind the front grille
of a packaged terminal air conditioner (PTAC). Refer to the PTAC
manufacturer's manual for instruction to remove the front grille.
Check clearance to ensure the fit of front grille after base module
installation. See below for a few location recommendations.

When Working With A Vertical Unit
1. Do not mount Module inside the cabinet of the unit, or in a
metal enclosure.
2. Mount on the outside of the unit to maximize wireless
communication.
When Working With A Metal Sleeve Cabinet, Room Cabinet,
or PTAC Cover
1. If cabinet has open bottom, mount the module just inside the
cabinet as close to the open bottom as possible without placing it in
danger of being bumped or touched by furnishings, vaccum, etc.
2. Another good module location would be on the underside of the
top of the cabinet or cover. Directly behind the open Louver/Grill.
