Hanging the Wired Controller
1. The controller wiring / cable can be installed in one of three direc-

is desired, remove cable guide grooves on the controller, and
then position wiring / cable on applicable side.
2. Choose and mark the area of installation. Use the provided parts
and screw the wall plate into place. Install the controller wall plate
to fit the electrical box if one is present. Ensure that no gaps exist
between the wall plate and the wall itself.
3. Arrange wiring / cables so as not to interfere with the controller
circuitry. Position the wired controller on the wall plate. Snap into
place by pressing the bottom part of the wired controller onto
the wall plate. Make sure that no gaps exist between the wired
controller and the wall plate on all sides.
4. To remove wired controller from the wall plate, insert a screw-
driver into the two holes at the bottom. Twist screwdriver to
release controller.
Do not damage the controller components
when removing.

Finalizing Indoor Unit Installation
1. Move the tubing clamp to its original position.
2. Ensure the three (3) hooks are properly attached to the installa-
tion plate by gently shaking the indoor unit from side to side.
3. Press the bottom left and right sides of the indoor unit against the
installation plate until the hooks click firmly into their slots.
4. Using two (2) Type “C” screws, secure the bottom of the indoor
unit to the installation plate.
5. Remove the two (2) tabs from the filter.
6. Replace the frame cover.

STANDARD WALL-MOUNTED INDOOR UNITS
Installation and Best Layout Practices
Assigning the Thermistor for Temperature Detection
Each indoor unit includes a return air thermistor assigned to sense the temperature. If a wired controller is installed, there is a choice of
sensing temperature with either the indoor unit return air thermistor or the thermistor in the wired controller. It is also an option to set both
thermistors to sense temperature so that indoor unit bases its operation on the first thermistor to reach the designated temperature differen-
tial. For applicable indoor units, an optional Remote Temperature Sensor can be used in lieu of the return air thermistor—either alone or in
conjunction with a wired controller thermistor as previously described.
