Remote Climate Control Module
The Remote Climate Control (RCC) module uses a microcomputer to analyze inputs from the in-car temperature sensor, ambient air temperature sensor, sunload sensor and function inputs made at the ICP by vehicle occupants. See Fig 1.
Using these inputs, the RCC module determines the correct outputs for A/C compressor clutch engagement and blower speed. The RCC module also determines outputs controlling the A/C air temperature control door, heater air damper door, windshield defrost door, and the A/C air inlet door positions.
The A/C air temperature control door is operated by an electric door actuator motor. The remaining distribution doors are controlled by vacuum actuated motors.
