  "textContent": "HVAC unit has a single blower fan (60), an evaporator (18) downstream of the blower (60) and a heater (20) downstream of the evaporator (18), wherein each zone outlet (28, 30, 32, 34, 36) includes a temperature mixing door (48, 50; 62) for controlling portions of hot and cold air and an output valve (39, 41, 52; 64) for controlling a zonal output flow rate. A method is devised to control the discharge of temperature-conditioned air from a plurality of zone outlets (28, 30, 32, 34, 36) of an automotive HVAC system via such an HVAC unit by the steps of reading an operator-requested zonal discharge blower level for each of the zone outlets (28, 30, 32, 34, 36); converting each zonal discharge blower level request to a zonal flowrate request; calculating a total requested output flowrate as a summation of all zonal flowrate requests; and adjusting a blower (60) voltage to a minimum voltage required for generating the total requested output flowrate.",
