Affected Component: EQUIPMENT:APPLIANCE:AIR CONDITIONER

Summary
This bulletin announces availability of new heater control panels assemblies with revised operating logic. Previously, when A/C cut-off control was activated (e.g. under full acceleration), the air inlet mode would be switched from inside (recirculation) to “fresh” and allow outside (fresh) air to enter the cabin. This is considered normal and intended operation, consistent with the design of the system. However, in the interest of customer satisfaction, these new control panels retain the selected air inlet mode regardless of a/c cut-off control status (off or on).
