Section 9. Climate Control
9.2 Aircraft Computer System (ACS) Interfaces
The ACS has control and monitoring functionality the four major subsystems of the
Climate Control System and provides the following functions:
1. Cabin and Cockpit Temperature Control
2. Bleed Air, Fan Air and Ram Air Control and Monitoring
3. Bleed Air Temperature Control
4. Air Conditioning Control and Monitoring
5. Windshield Defog
6. Cabin Dehumidification
7. Manual and Automatic Pressurization Control and Monitoring
8. Over-Temperature Protection
Pilot inputs to the climate control system are made through the environmental
(ENVIR) and pressurization (PRESS) synoptic pages as well as the Cabin Air Source
selector on the left switch panel. Synoptic inputs are sent through the PFD, while the
Cabin Air Source switch position is first sent through the center switch panel, then to
the PFD. From the PFD, inputs are sent to the ACS which then configures the
climate control system components by turning on and off applicable Electronic Circuit
Breakers (ECBs). The ECBs for the climate control system are located within the Aft
Power Distribution Center in Electronic Circuit Breaker Units (ECBUs) four and five.
Cabin pressure regulation is accomplished through the primary outflow valve and
controlled directly by the left ACS. Normal operation of the pressurization system is
automatic, however direct pilot inputs are accomplished through the pressurization
(PRESS) synoptic page.
Several sensors send status information on the climate control system to the ACS' for
display on the MFD. Sensor information related to the left engine is sent to the left
ACS while information related to the right engine is sent to the right ACS.
