This disclosure relates to methods, systems, and devices for detecting an operational mode of a building component of an environmental control system. In some instances, the apparatus may include a sensor for outputting a signal related to a measure of power drawn by the building component. The sensor may be a current sensor associated with a power cord of an air conditioning unit. The signal output by the sensor may be received by a signal conditioning circuit for conditioning the signal received from the sensor such as, for example, by amplifying and/or filtering. A comparator may be configured to compare the conditioned signal to a specified threshold associated with an ON condition and/or an OFF condition of the building component. The apparatus may include a wireless interface configured to wirelessly transmit a determination of whether the building component is ON or OFF based on the result determined by the comparator.

Method and system for detecting an operational mode of a building control component

A protocol independent programming tool for constructing control logic. The control logic may be constructed without dealing in the details of an underlying protocol. The protocol details may be abstracted and exposed and generic points used in constructing the logic. The tool may automatically map or translate the points used in the logic to protocol specific entities.

Protocol independent programming environment

A priority selection mechanism for driving outputs from control logic which can be automatically translated to controllers of various protocols. The priority selection mechanism may assign a priority to the outputs and select the output having the highest priority as the output of the control logic. There may be an abstract representation of the priority logic which may permit a protocol mechanism to be used in the logic without the designer or user needing to know the details of the mechanism.

Priority selection mechanism for driving outputs from control logic for controllers of various protocols

A graphical approach to setup data sharing between two controllers. Symbols that represent controllers may be placed on a wiresheet. A link may be constructed between the controllers by connecting the symbols with a line drawn between them. The resulting link information may lead to a compile and download of binding tables to the pertinent controller. The designer or user need not setup several levels of mapping by populating multiple tables to effect the binding for a link between the controllers. This binding may be done automatically under a hood without the designer or user needing to be aware of the binding activity. This approach for graphically constructing a link may be particularly applicable to BACnet controllers.

Graphical approach to setup data sharing between two controllers

A mechanism for constructing generic control logic with versions of the logic automatically generated and stored for one or more protocols. The complexity of the one or more protocols may be hidden under a hood of the mechanism from the view of engineers, programmers and users so as to improve their productivity relative to control logic designs and applications.
