Single-package air conditioner and methods of operation

A single-package air conditioner unit, as provided herein, may include a cabinet, an outdoor heat exchanger, an indoor heat exchanger, a compressor, and a controller. The cabinet may define an outdoor portion and an indoor portion. The outdoor heat exchanger may be disposed in the outdoor portion. The indoor heat exchanger may be disposed in the indoor portion. The compressor may be in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant therebetween. The controller may be in operative communication with the compressor. The controller may be configured to initiate a conditioning operation. The conditioning operation may include receiving a demand response signal corresponding to electric power access, determining occupancy of an indoor environment, and initiating a responsive conditioning cycle in response to receiving the demand response signal, the responsive conditioning cycle being based on the determined occupancy.

VENTILATION FAN AND VENTILATION SYSTEM

A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.

Occupancy sensor range determination

A load control system may be configured using a graphical user interface software. The graphical user interface software may display a first icon and a second icon. The first icon may represent a first electrical device and the second icon may represent a second electrical device. The first icon and the second icon may represent the relative location of the first electrical device and the second electrical device within a load control environment. The graphical user interface software may display a line from a selected icon (e.g., first icon) to a cursor. The graphical user interface software may adjust the line from the selected icon, for example, as the cursor moves. The graphical user interface software may define and store an association between the first electrical device and a second electrical device, for example, in response to the user selecting the first icon and the second icon.
