Control Module HVAC: Description and Operation
Air Conditioning Control Module (A/CCM)
The A/CCM is located on the right hand side of the air conditioning unit and controls all system functions.
The temperature within the passenger compartment is continually compared with the temperature selected on the control panel LCD. The A/CCM
receives data input signals and compares these with signals from the system temperature sensors and feedback devices. Based on this information the
A/CCM adjusts the air outlet temperature, airflow and distribution from the air conditioning system into the passenger compartment.
