Abstract
An air duct type multizone air conditioning system having air dampers and corresponding thermostats in respective zones under the control of a main controller. The main controller can override desired temperatures selected by the corresponding thermostats in any of the zones and automatically detects the number of the number of zones, the presence of an auxiliary heater, and a heat pump, and the presence of an air damper and corresponding thermostat properly located in the same zone. The main controller also receives information regarding the operating cost of the heat pump and the auxiliary heater to ensure their cost-effective use.
