Zusammenfassung:	Disclosed is a system for independently controlling the climate within a primary zone and at least one secondary zone of a building. The system comprises a primary packaged unit comprising a primary indoor coil and a primary variable speed indoor fan blowing over the primary indoor coil to serve the primary zone of the building. The system further comprises a secondary unit comprising a secondary indoor coil circulating the refrigerant and a secondary variable speed indoor fan blowing over the secondary indoor coil to serve a secondary zone of the building. The primary unit and the at least one secondary unit shares a common variable speed compressor, outdoor coil, and an outdoor fan that are disposed within the primary unit. First and second solenoid valves in the primary unit selectively control refrigerant flow to the primary and secondary units to enable independent control of the zones.
