The current application is related to environmental-conditioning systems controlled by intelligent controllers and, in particular, to an intelligent-thermostat-controlled HVAC system that detects and ameliorates control coupling between intelligent thermostats. Control coupling can lead to inefficient HVAC operation. When control coupling is detected, a settings-adjustment directive is sent to at least one intelligent thermostat to adjust one or more intelligent-thermostat settings, including an HVAC-cycle-initiation delay parameter, swing parameter, and a parameter that indicates whether or not an intelligent thermostat should first obtain confirmation or permission before initiating an HVAC cycle.

The all weather outdoor equipment cover for placement outdoor air conditioner condenser unit. The current invention of the cover provides top surface of the cover an incline/protrusion/projection/dome shaped surface/raised surface/bulging/arched surface so rain water does not accumulate even if the top surface of the equipment it's placed over has a substantial flat top surface. The cover can have varying thicknesses across the top surface to create substantial incline or slop when placed over a substantially flat surface. The cover can be used to cover outdoor ac units, outdoor/patio furniture with substantial flat surfaces to eliminate accumulation of rain water over the top surface of the cover or the equipment.

An infrared sensor is installed to one of the corners of a decorative panel to face different directions at the respective corners. A controller controls one of several air direction vanes and thus airflow out of one of air outlets and an air-conditioning apparatus to perform an operation, makes a determination of the installation position of the infrared sensor from one of several divided areas in which a temperature difference in floor surface between before and during an operation of the one of the air direction vanes equals or exceeds a specified value, a disposition position of the one of the air direction vanes, and an installation direction of the infrared sensor, and makes the one of the divided areas in which the temperature difference equals or exceeds the specified value correspond to the one of the air direction vanes to be controlled.

A user-friendly programmable thermostat is described that includes a body having a central electronic display surrounded by a ring that can be rotated and pressed inwardly to provide user input in a simple and elegant fashion. The current temperature and setpoint temperature are graphically displayed as prominent tick marks over a range of background tick marks on the electronic display. Different colors can be displayed to indicate currently active HVAC functions, and different intensities of colors can be displayed to indicate an amount of heating or cooling required to reach a target temperature. The setpoint temperature for the device can be altered by user rotation of the rotatable ring, and the programmed schedule can be displayed to the user and altered by the user by virtue of rotations and inward pressings of the ring. Initial device set up and installation, the viewing of device operation, the editing of various settings, and the viewing of historical energy usage information are made simple and elegant by virtue of the described form factor, display modalities, and user input modalities of the device.

An indoor unit includes a housing that houses an electrical-component storage box that includes a body portion, a lid portion, and an engagement mechanism portion that engages the body portion and the lid portion with each other in a detachable manner. The lid portion covers an open region on a side of the body portion. The engagement mechanism portion includes an engagement claw portion provided at one of the body and lid portions and an engagement hole portion into which the claw portion is inserted, and which is formed at the other of the body and lid portions.

Provided is an installation guide system for an air conditioner. The installation guide system may include a display that displays a user interface for designing an installation for an air conditioner, a memory that stores at least one image for a building in which the air conditioner is installed, and a controller to control a display of the stored images on the user interface. The user interface may include a first region that displays the stored image including a plurality of tubes that connect an indoor unit to an outdoor unit of the air conditioner, and a second region that displays information regarding an interference between at least two of the plurality of tubes.

According to one embodiment, an outdoor unit equipped with a communication unit and a controller. The communication unit communicates data in a noncontact manner to an information terminal close to the outdoor unit. The controller permits the setting of data that has been input from the information terminal via the communication unit only during a fixed period of time after the outdoor unit has been turned on.

A thermostat that is configured to be releasably secured to a wall mountable connector, wherein the wall mountable connector includes a jumper switch that permits an installer or other professional to easily form an electrical connection between different wiring terminals of the wall mountable connector in accordance with how particular field wires are connected to the wiring terminals of the wall mountable connector. The thermostat is further configured to automatically determine the position of the jumper switch of the wall mountable connector, and in some cases, change the control of at least some functionality of the thermostat and/or HVAC equipment depending on the position of the jumper switch.

An installation guide system for air conditioner and a method of using the same are provided. The system includes: a memory unit storing drawing information on a building where an air conditioner is to be installed; a display unit providing a user interface to design an arrangement of the air conditioner; a drawing displaying unit provided on the display unit, where at least one apparatus constituting the air conditioner is inserted; an effectiveness inspection selecting unit performing a verification on an capacity of an apparatus constituting the air conditioner on the basis of the design information on the air conditioner; and a system inspection displaying unit displaying a verification result on whether the capacity of the apparatus is within a predetermined reference range.
