Range between the WRT1 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 higher if in a basement or further away from large metal objects.
The base module is designed to be mounted behind the front grille of your Friedrich packaged
terminal air conditioner (PTAC). Refer to the Friedrich PTAC Installation & Operation Manual for
instructions in removing the front grille. Check clearance to ensure the fit of front grille after base
module installation. Ensure if mounting with screws that wires and lines are not damaged. See
below for a few suggested options to mount the base module.
Note:
It is recommended to use an adhesive
tape instead of screws when mounting
the Base Module inside the PTAC
housing.
Note: For Friedrich Single Package Vertical Air Conditioners (Vert-I-Pak®) install module on the
outside of the unit, in close proximity to the low-voltage terminal board.
