摘要：A controller for an HVAC system having a plurality of zones and having amultiple stage fluid temperature conditioning device. The controller is configured toreceive a plurality of thermostat signals and to transmit a signal to control one of aplurality of flow control devices in response to a call for conditioning in one of the

plurality of zones. The controller also includes one or more timers that are connected tothe thermostat terminals, where the one or more timers are configured to initiate aseparate timing count upon each call for conditioning in any one of the plurality of zones.In addition, the controller includes one or more staging terminals for transmittingstaging signals to control a multiple stage fluid temperature conditioning device, wherethe transmission of the staging signals determines whether the conditioning device willoperate at a relatively higher output stage. The controller is also configured to make atiming count determination to determine if any one of the separate timing countsinitiated upon each call for conditioning in any one of the plurality of zones exceeds atiming delay parameter. The transmission of staging signals depends on the timing countdetermination. A method is also disclosed.
