An air conditioning control system includes an air conditioner, an air conditioning control device with a display, and an operation terminal with a camera. First authentication information included in a two-dimensional code displayed in the display in the air conditioning control device is collated with second authentication information acquired from the two-dimensional code imaged by the camera in the operation terminal and included in registration information transmitted from the operation terminal, to determine whether the first authentication information and the second authentication information match with each other. In response to the first authentication information and the second authentication information being determined to match with each other, the operation terminal that has terminal information included in the registration information is successfully authenticated and registered as an operation terminal that is enabled to perform a remote operation of the air conditioning control device.

Methods, devices, and systems for space conditioning based on weather information are described herein. One device includes a memory, and a processor to execute executable instructions stored in the memory to receive forecasted weather information, determine, based on the forecasted weather information, future weather conditions, determine based on the future weather conditions and historical setpoint data, whether conditioning of a space is expected, and generate an alert in response to conditioning of the space being expected.

Apparatus, systems and methods for ascertaining the occupancy of a building are presented. The building is divided into one or more control zones which correspond to physical areas of the building associated with controllable modules, such as HVAC units, lighting, irrigation, or other environmental features such as fountains, music, video, and the like. Zone parameters define how zone devices shall react to the number of occupants located in the particular zone. A building control system detects individual mobile devices in and around the building, and determines the locations of each device by using trilateration and/or location services. The identified mobile devices act as proxies for building occupants. The locations of these devices are correlated with the locations of the zones in the building, and the building control system then adjusts the operating parameters of the zone based on the number of devices present in the zone.

To propose a technique by which an air conditioning device can be efficiently set up. An aspect of the present disclosure relates to a program for implementing, on a terminal, an application that controls a user-side device or a heat-source-side device of an air conditioning device. The program causes the terminal to execute a process including displaying, by the application, a setting screen on the terminal. The setting screen includes identification information, a setting item, and a drive indicator of the user-side device or the heat-source-side device.

A communication unit is provided for an air treatment apparatus. The communication unit includes a receiver, a transmitter, and a storage. The receiver receives measurement data sent from a measuring apparatus separate from the air treatment apparatus. The measuring apparatus is movable. The transmitter transmits, to a server, the measurement data associated with specific information of the air treatment apparatus. The storage stores the measurement data therein. If a storage process in which the measurement data is stored in the storage is completed, the transmitter transmits, to the measuring apparatus, information indicating that the storage process has been completed.

A drain cleaner apparatus for dispensing a cleaning composition into a condensate drain line of an air handler of an air conditioning system. The drain cleaner apparatus includes an apparatus reservoir configured to hold the cleaning composition, a connector interface configured to couple with the condensate drain line to cause an apparatus outlet of the drain cleaner apparatus to be in fluid communication with an opening of the condensate drain line, a dispenser device that is configured to be actuated to selectively dispense an amount of the cleaning composition from the apparatus reservoir and through the apparatus outlet, and a controller configured to actuate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention.

A HVAC control system comprising a user interface adapted to receive comfort feedback from a user. A processor is adapted to receive the comfort feedback and input data corresponding to one or more comfort factors and respective values of the comfort factors. The processor is adapted to build a comfort model for the user based on the comfort feedback and the input data, with the comfort model correlating a comfort score to one or more values of one or more of the comfort factors. The processor is configured to adjust one or more functions of an HVAC unit to vary one or more comfort factors such that a predetermined comfort score is achieved. An associated method and an associated system are also provided.
