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

1.2 Mounting Locations
For greater temperature accuracy, follow these mounting
recommendations:
• Mount sensor vertically.
• An ideal location is under a north eave or on a
northern exposure away from direct sunlight, as
shown in Figure 2. In these cases, the quick-
connect cable is not used. Four-conductor, 22-
AWG, shielded cable must be pulled from the
display to the temperature sensor location. Route
the cable through conduit when exposed to
outdoor conditions. The maximum length of the
cable should be no more than 500 feet.
• Mount the sensor above grass or vegetation
rather than concrete or other pavement.
• Mount at least 20 feet away from chimneys,
vents, air conditioners, or other items that would
influence correct temperature readings.
• Do not mount the sensor between displays or locations that restrict air movement.
• Mount the sensor so the cable is protected from weather and vandalism.
