2.5 SYSTEM OPERATING CONTROLS AND COMPONENTS
The unit is furnished with a microprocessor control system. Once the setpoint is entered at the Cab Command, the
unit will operate automatically to maintain the desired temperature within very close limits. See Section 3.2.1.
Beware of unannounced starting of the evaporator or condenser fans. The unit may cycle fans
unexpectedly as control requirements dictate.
Under no circumstances should anyone attempt to repair the microprocessor module or Cab
Command! Should a problem develop with these components, contact your nearest Carrier
Transicold dealer for replacement.
