Abstract: Systems/methods for intelligent commissioning of an HVAC system provide a control node and at least a first network node coupled to communicate with the control node, the first network node configured to retrieve via a user interface objects configured at the control node, configure at least a second network node using the retrieved objects, and report the configuration of the second network node at the control node. A user interface of a first network node can access the objects at the control node. The first network node can apply the accessed objects to configure a second network node using a commissioning tool. The commissioning tool can be activated specifically for certain authorized HVAC personas or roles. The first network node can report the configuring at the control node. The commissioning tool can be voice-enabled to allow a single user to configure the HVAC system via voice commands.

Abstract: A pressure transducer arrangement and method of operation is provided. The pressure transducer and methods of operation reduce error in determining an offset value by eliminating error relating to fluid flow through the transducer arrangement when the offset value is determined. In a particular embodiment, the apparatus and method includes a lockout valve that prevents fluid flow between first and second fluid pressure sources when the offset value is determined.

Abstract: BACnet objects and methods for efficiently monitoring the communication status of networks and devices in a building automation and control system are presented. A pair of bus communication status objects, including a server object and a client object, provide the communication status of an MS/TP network as an OCTET String transmitted only upon a change of value (COV) of the communication status of a device on the network. Individual devices may be monitored with a device communication status object, in conjunction with or apart from the bus communication status objects. For MS/TP devices, automatic configuration and monitoring in a controller is provided. For other devices, a user interface is provided through a graphical tool to allow configuration to specify the desired device and/or network for monitoring.

Abstract: An apparatus and method are provided for determining the temperature of an operating fluid media in an HVAC system. An integral temperature sensor, mounted within an actuator of an actuator-driven HVAC valve, senses the temperature of a valve body of the HVAC valve. The temperature of a fluid media within the HVAC valve is determined from the temperature of the valve body. A processor within the actuator configures the actuator to function in either a direct acting mode, or alternatively in a reverse acting mode, as a function of the temperature of the valve body as sensed by the integral temperature sensor. The actuator is adapted for attachment to the HVAC valve in such a manner that the temperature sensor is placed in operative thermal contact with the valve body by the act of attaching the actuator to the HVAC valve.
