Claim:
1. A method for controlling a heating, ventilation, and air conditioning (“HVAC”) system, comprising: maintaining a discharge fan capacity at a low fan capacity setting; and varying a coil discharge air temperature between a low discharge air temperature limit and a high discharge air temperature limit; when the coil discharge air temperature reaches the low discharge air temperature limit, varying the discharge fan capacity between the low fan capacity setting and a high fan capacity setting so as to maintain a space temperature at a space temperature setpoint, while maintaining the coil discharge air temperature at the low discharge air temperature limit, and when the coil discharge air temperature reaches the low discharge air temperature limit and the discharge fan capacity reaches the high fan capacity setting, varying the coil discharge air temperature between the low discharge air temperature limit and a boost low discharge air temperature limit that is lower than the low discharge air temperature limit.
