HVAC Control Module

The DATC system uses a remote HVAC control module that is separate from the control interface. The FCIM provides the interface for the vehicle occupants to control the climate control system. When selections are made, the FCIM communicates the selections to the HVAC control module over the vehicle module communication network. The remote HVAC control module controls the climate control system based on the FCIM selections or automatically controls the climate control system in the AUTO mode.
