2、Stuyresctonetrmol has two modes【n.模式；#方 式】,AUTO and MANUAL.In the AUTO mode,the cool or warm signalfrom the selector switch goes to the cabin temperature controller（CTC）.The CTC compares the selector（temperature）input to inputs from theduct temperature anticipator【n.预感器】,duct limit sensor and cabin

3、temperature sensor.The CTC monitors the sensor inputs.It calculatesthe correct temperautre for the pack air.The CTC sends a signal to set the position of the air mix valve.,飞机机电设备维修专业教学资源库Aircraft Maintenance Engineering（ME）,Temperature Control System,Temperature Control System,飞机机电设备维修专业教学资源库Aircra
