The standard automatic temperature control HVAC system allows for the temperature of the cab to be controlled by continuously varying the position of a water valve and appropriately turning on and off the operation of the A/C compressor. The temperature can be controlled by the HVAC automatically or manually by the operator. The HVAC system is electronically controlled through the Chassis ECM and Brake ECM.
