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.
Specifications are subject to change without notice.
