The disclosure includes an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment the network includes a duct, a blower and a controller. The blower is configured to receive a control message from a data bus. The duct is configured to direct air flow from the blower. The controller is configured to publish the control message to the data bus. The controller thereby commands the blower to provide air to the duct at an initial volume rate and to increase the volume rate until the controller detects onset of a cutback mode of the blower.
