There is described a system and method for high ventilation using outdoor air in an indoor area comprising an HVAC unit and a controller. The HVAC unit includes at least one damper and a fan. The controller detects an activation of an emergency purge mode, adjusts the at least one air damper to allow a maximum of outside air to flow through the HVAC unit without circulating return air, and establishes a fan speed of the fan for maximum outside airflow through the HVAC unit. The controller also modifies the fan speed of the fan based on an occupant comfort criteria without regard to energy efficiency of the HVAC unit. The fan speed is modified based on a delta enthalpy of the HVAC unit and a nominal capacity of the HVAC unit.

System and method for high ventilation of outdoor air

There is described a system and method for configuring, commissioning and troubleshooting an HVAC unit. A unit type configuration is established based on a type of HVAC system and temperature data, humidity data, and/or indoor air quality data. A fan configuration is established based on whether a variable frequency drive fan is identified. Cooling and heating stage configurations are established based on a compressor parameter and a heating stage parameter. An available auxiliary termination is identified in response to establishing the configurations. A safety is assigned to the available auxiliary termination in response to identifying the available auxiliary termination. An IO table is provided to an HVAC controller, which includes physical input/output assignments for the terminations of the HVAC controller based on the configurations and the assigned safety. For another embodiment, the fan configuration is established based on one of a traditional stage blower fan or variable frequency drive fan.

System and method for configuring, commissioning and troubleshooting an HVAC unit

Systems and methods for improving energy efficiency in a heating, ventilation, and air conditioning (HVAC) system using a control device and a controllable component are provided. A climate control system for a facility includes a heating/venting/air-conditioning (HVAC) system, at least one controllable component configured to adjust environmental conditions automatically to minimize energy usage, a control panel, and a control device, wherein the control device displays data from the climate control system and includes a user interface through which a user can control the climate control system.

Method and system for adaptive control for thermostats

An approach for changing behavior of users of a building automation system by employing gaming function logic and providing feedback to the building automation system users.

Gaming approach for energy efficient building control

A method for execution on a computing device includes transmitting first identification information to a server processing circuit via the Internet. The server processing circuit identifies a plurality of geographically dispersed systems corresponding to the first identification information. Information including geographical coordinates and system status information is received for each system. A set of geographical boundary coordinates are determined. Moreover, a visible characteristic value for each system is determined based on the corresponding system status information. A map presentation function executed by a second processing circuit displays a map based on the geographic boundary coordinates, and displays a plurality of visible indicators on the map. Each of the plurality of visible indicators has a position on the map corresponding the geographical coordinates of a corresponding system. Each of the plurality of visible indicators has a visible characteristic corresponding to the visible characteristic value of the corresponding system.
