1.1 Temperature Sensor Overview
The temperature sensor enclosure is made up of eight plastic
disks, a metal mounting bracket, and a 25-foot weather resistant
cable. Refer to
Figure 1 .
In most cases, the enclosure will be mounted using two screws.
The cable will be plugged into the back of the display.
In certain cases, it may be necessary to disassemble the enclosure
or rewire the temperature sensor board. Instructions are
provided for those situations. If replacement or additional parts
are needed, refer to the following chart for part numbers.

1.2 Mounting Locations
For greater accuracy of temperature, follow these mounting recommendations:
•
An ideal location is under a north eave or on a northern exposure away from direct
sunlight (
Figure 4 ).
•
Mount the sensor above grass or vegetation rather than concrete or other paving.
•
Mount at least 20 feet away from chimneys, vents, air conditioners, or other items that
would influence correct temperature readings.
•
Do not mount between displays or in any location that restricts air movement.
•
Mount the sensor so that the cable can be protected from weather and vandalism.
The most common locations for the temperature sensor are on the display cabinet (
Figure 2 ),
or on the display structure ( Figure 3 ). A light-colored display is preferred in this location.
Location of the sensor should be below or on a northern edge of the display to keep the
sensor shaded.
