The disclosed energy management system pairs zones and respective HVAC units for the zones. In addition to each zone having conventional primary supply and return air diffusers connected to its HVAC unit, there is an additional diffuser in each zone connected to the HVAC unit of the paired zone. A valve controls the air flow from each HVAC unit: to only the primary diffusers for its zone; or to both the primary diffusers for its zone and the additional diffusers for the other paired zone. Control stats in each zone determines the HVAC demand for that zone; and responsive to the first demand from either zone, operate the HVAC unit for that zone. Simultaneously, the energy management control locks out the other HVAC unit to prevent its operation. Upon a concurrent demand from the paired zone, the valve of the first activated HVAC unit shifts, to divert some of its conditioned air to its paired zone. A thermostat sensing outdoor temperatures, allows the sytem to function only when the outdoor temperature is within a reasonably moderate range, approximately midway between the zone comfort temperature, such as 70°F., and the lowest and/or highest design temperatures for the HVAC units.

An energy management system for use with two HVAC units for conditioning two interconnected zones, each zone having first and second supply diffusers for discharging conditioned air from the respective HVAC unit and a return diffuser for returning air back to such HVAC unit; and stat means in each zone signaling a demand for conditioned air and for operating the HVAC unit for such zone; the improved combination of the separate zones and the respective HVAC unit, being paired, including having an additional supply air diffuser in each zone, and means connecting such additional diffuser in each zone with the HVAC unit for the other zone; thermostat means to sense the outside ambient temperature, and a control operable when such outside ambient temperature is outside of a specific temperature range to render the energy management system inoperable; first valve means connected between each HVAC unit and the additional diffuser in the other zone, for selectively opening and closing air flow from such HVAC unit to the other zone; second valve means connected between each HVAC unit and the second supply diffuser in its zone, for selectively opening and closing such second diffuser; means for locking out the operation of the HVAC for the other zone, responsive to the thermostat means signaling a demand in the first of either paired zone and for operating the HVAC unit for such first zone; and means for opening the first valve means of the operating HVAC unit of the first zone for diverting some of the conditioned air flow from such unit to the other zone, and for closing the second valve means of the operating HVAC unit of the first zone for reducing conditioned air flow from such unit to its zone, responsive to the subsequent but concurrent demand for conditioned air in the other zone.
