All sensor options ship in the main control panel and
are field installed. Programmable option installation
procedures.
Mounting Location
Mount the sensor on the wall in an area with good air
circulation at an average temperature. Avoid mounting
space temperature sensor is areas subject to the
following conditions:
• Drafts or “dead” spots behind doors or in corners
• Hot or cold air from ducts
• Radiant heat from the sun or appliances
• Concealed pipes and chimneys
• Unheated or non-cooled surfaces behind the
sensor, such as outside walls
• Airflows from adjacent zones or other units
To mount the sensors, remove the dust cover and
mount the base on a flat surface or 2" x 4" junction box.
Sensors ship with mounting screws.
Mounting the Subbase
Remove the zone sensor cover from subbase, and
mount subbase on the wall or on a 2" x 4" junction box.
Route wires through the wire access hole in the
subbase. See
Figure 35, p. 47 . Seal the hole in the wall
behind the subbase.
