Automatic Climate Control Operation
The display provides the operator with information
about the system’s performance.
● It provides the desired cab temperature reading
selected by the operator. The display reading
may be in Fahrenheit or Celsius. To make the
change between reading there is an in-line
connection in the cab main harness under the
instructional seat. Completing this connection
provides for Celsius readings. This connection is
set at the manufacturer for the appropriate
country or region.
● It illuminates an icon “A” when the system is
operating in the automatic climate mode.
● When the “A” is not illuminated the blower motor
speed MUST be manually controlled and “Auto”
mode will only control the water valve and
compressor, while trying to maintain the set
temperature.
● It illuminates the windshield icon when the
system is in the Defog Mode.
● It illuminates the book icon when the system is
not operating correctly. Along with the book icon
a fault code will also be displayed to assist the
technician making the correct repairs.
The range for the Automatic Temperature Control is
from a set point of 16 to 30°C (61 to 89° F). The set
point of 16 to 32° C (60 to 90°F) will be displayed and
the “A” icon on the display will be ODD when the
system is in maximum mode.
