3. Mounting Instructions
1. Select location for installation.
• Select a place where the sensor will detect an average temperature of the
room.
• Make sure that the sensor is not in direct sunlight, miscellaneous heat
sources, drafts, outside wall or supply air from the unit itself. These may
generate incorrect readings.
• Drill or cut open a hole into the wall where the sensor will be installed. For
hollow walls, the hole should be ½".
• Mount the sensor with the threaded insert inside of this hole by turning it
clockwise until it sits flush with the wall.
• When mounting into solid walls (i.e. marble or rock) a ¼" hole is
recommended, and the threaded corkscrew insert is not required.
• Field wire must be provided on site.
2. Connect the wires.
• Connect the sensor wires to the field wires using crimp connectors or wire
nuts.
• Connect the loose end of the field wires to the wires extending from the noise
filter board.
• Connect CN20 connector from the noise filter board to CN20 on the indoor
unit control board.
