AIR INTAKE CONTROL OPERATION [FULL-AUTO AIR CONDITIONER]
id0740a1103500
Air Intake Automatic Control
• The climate control unit calculates the cabin temperature based on the ambient temperature and sunlight intensity in order to cool the cabin temperature quickly according to the cooling conditions. It then compares the calculated cabin temperature and the actual cabin temperature to determine the proper air intake mode.
Correction
Defroster correction
• When the DEFROSTER switch is turned on, the air intake is set to FRESH to improve defrosting. The air intake is set to FRESH even if it has been set to REC manually.
Ambient temperature correction
• When the ambient temperature is 5 °C {41 °F} or less, the air intake is set to FRESH to prevent window fogging.
Recirculate correction
• When the pressure sensor signal is more than 2.6 MPa {27 kgf/cm2, 377 psi} to the climate control unit, A/C is ON and air intake mode is FRESH. The air intake actuator operates and turns the air intake mode to RECIRCULATE for improve cooling effectiveness.
• If there is an error in the refrigerant pressure signal, the climate control unit turns off the A/C and the A/C display, and the system returns to normal air intake control.
Air Intake Manual Control
• The air intake modes can be switched by operating the REC switch.
