Abstract
An HVAC control system for a vehicle with multiple environmental zones includes a datalink between the control elements of the HVAC systems that regulate the climate in the multiple environmental zones. Control elements for the HVAC systems include an electronic control unit and a control head. A user of the HVAC control system may assign master status to the control head of the zone in which the user is located, and from that control head, control the environmental settings for HVAC systems servicing other zones in the vehicle. A data communication bus implemented in the vehicle may be used as the datalink.
