An energy analysis system provides valuable input into building energy expenditures. The system assists with obtaining a detailed view of how energy consumption occurs in a building, what steps may be taken to lower the energy footprint, and executing detailed energy consumption analyses. The analyses may include, as examples, a balance point pair analysis to determine either or both of a heating balance point and a cooling balance point, an exception rank analysis to identify specific data (e.g., energy consumption data) in specific time intervals for further review, or other analysis. The system may display the analysis results on a user interface.

The disclosure provides systems and methods of use of an HVAC graphical interface dashboard. In various embodiments the dashboard includes a weather tab, wherein invoking the weather tab advances to a weather screen. The dashboard also includes an indoor humidity tab, wherein invoking the indoor humidity tab advances to a humidity screen which displays at least a current indoor humidity, wherein the humidity screen interprets a percentage of humidity for a user. A programs tab and a home tab are also provided. A button of the dashboard turns a color, such as an inverse color, when it is touched.

The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment, the HVAC data processing and communication network includes a system device, a subnet controller and a user interface. The system device is configured to receive a control message from a data bus and operate according to a control setting communicated thereby. The system device is further configured to generate an alarm message in the event that the device enters an alarm state in response to an alarm condition. The user interface is configured to receive the alarm message and display alarm information in response to the message. The subnet controller is configured to provide operational control of the system device via the control message. The operational control is decoupled from the alarm message.

Alarm and diagnostics system and method for a distributed- architecture heating, ventilation and air conditioning network

A zone control panel that is easy and intuitive to use and to program. In some embodiments, a zone control panel may be configured to have an easy to use, single level menu structure with, for example, a configuration mode and/or a checkout mode. The configuration mode may, if present, include a number of menu screens sometimes without any sub-menu levels. Likewise, the checkout mode may, if present, include a number of menu screens sometimes without any sub-menu levels. A mode selector may be provided to select a particular mode, after which, the menu screens that correspond to the selected mode may be sequentially displayed to the user. Other features and aspects are also disclosed.

An HVAC data processing and communication network includes a first subnet and a second subnet. The first subnet includes a first demand unit, a first comfort sensor and a first subnet controller. The second subnet includes a second subnet comprising a second demand unit, a second comfort sensor and a second subnet controller. The second subnet controller is configured to control an operation of the first subnet.

Communication protocol system and method for a distributed-architecture heating, ventilation and air conditioning network

A system and method to control environmental parameters of pre-defined zones within an environment using an electronic controller are disclosed. The system includes a non-proprietary electronic controller which enables a weighting value to be assigned to each zone within the environment. The electronic controller also detects any zone service calls from sensor devices associated with each of the zones and determines a cumulative weighting value in response to the detected zone service calls. The electronic controller selects an equipment staging combination from at least two possible equipment staging combinations in response to thermal capacity, and an air handler stage is selected in response to at least the cumulative zone weighting value.

System and method for heat pump oriented zone control

A small duct high velocity (SDHV) damper assembly. The SDHV damper assembly includes a generally tubular damper housing having first and second ends, wherein each of the first and second ends is adapted for insertion into associated high velocity ductwork respectively. A damper blade or an expandable damper member is situated within the damper housing to restrict flow in the damper housing in a controlled manner.

A foldably tensioned boot loadable air damper device for controlling the flow of air through ductwork, and a method of installing same. The damper device includes an actuator having a retractable member and a pivoting member, wherein the pivoting member is operatively connected to the retractable member of the actuator. The damper device also includes at least one support base supporting the actuator and the pivoting member with respect to each other, a foldable damper blade attached to the pivoting member, and at least one tensioned hinge member operatively connected to the foldable damper blade for unfolding the damper blade. The damper device may be inserted through a register boot and into a ductwork when folded.
