An air-conditioning remote controller for operating an air-conditioning apparatus is provided. The air-conditioning remote controller includes a display unit, an image acquisition processing unit, and a display processing unit. The display unit displays various information. The image acquisition processing unit acquires image data from an external communication terminal. The display processing unit displays, on the display unit, a settings management screen used for operating the air-conditioning apparatus, and the image data acquired by the image acquisition processing unit from the communication terminal.

Air-conditioning remote controller

An air-conditioning apparatus controller includes a light-emitting indicator that emits light in a plurality of colors, a main display that displays a setting screen for light-emitting indication by the light-emitting indicator, a touch panel through which an instruction related to settings displayed on the main display is input, a data processing unit of a controller that causes the main display to display the setting screen, and performs setting processing for assigning an indication color to an indication content to be provided by the light-emitting indicator, in accordance with the instruction transmitted from the touch panel, and a data storage unit that stores settings for the processing performed by the data processing unit.

Air-conditioning apparatus controller and air-conditioning system

A first communication section in an optical communication interface communicates with outdoor units and indoor units using a first communication method. A central management controller communicates with the optical communication interface using the first communication method and manages the outdoor units and the indoor units according to the first communication method. A second method communication section in a second communication method indoor unit of a different manufacturer communicates with a second method communication section in a second communication method outdoor unit using a second communication method. The optical communication interface and the second communication method indoor unit exchange information by optical communication with each other using respective optical communication sections.

Equipment item management system, control method thereof, and equipment item management apparatus

A centralized controllercontrols facility equipmentandaccording to a sequence control program corresponding to standard functions of the facility equipmentand. In addition, the centralized controllerreceives control information for controlling a unique function of the facility equipmentandand a PIN code, which are transmitted from a programmable controller, and transmits, if the PIN code is a valid code, the control information to the facility equipmentand

Equipment management system, programmable controller and centralized controller

Even at spots, such as a window side and the back side of a room, where air conditioning loads are different from each other, comfortable air conditioning is obtained at low cost using a common air conditioning unit. One indoor apparatus and wireless transceiver having a ZigBee-compliant transmission device are installed in the room. Sensor units having temperature/humidity sensors and ZigBee-compliant wireless transceivers are installed at plural indoor spots where the air conditioning loads are different from each other. A controller in the indoor-apparatus receives sensor information (temperature/humidity information) via the wireless transceivers from the sensor units, and computes a weight average based on the sensor information and weight values that are pre-stored in the storing devices and that correspond to the sensor units. Using the computed value as a control value, the controller controls an air conditioning unit.

Air conditioning system

An air-conditioning system capable of reducing traffic of signals and effectively performing control and management operations without causing heavy traffic is obtained. In an air-conditioning system including one or more indoor units, one or more outdoor units, and a centralized control apparatusand performing signal communication, a transmission relayis provided between a first transmission lineto which the one or more outdoor unitsand the centralized control apparatusare connected and a second transmission lineto which one or more indoor unitsconstituting a group are connected, the transmission relayrelays a signal between the first transmission lineand the connected second transmission line. The transmission relayfurther includes arithmetic processing meansfor processing data included in the signal transmitted via the connected second transmission line, and data storage meansfor storing data regarding the processing by the arithmetic processing means

Air-conditioning system

There is provided a compact centralized management unit of facility equipment, as well as a management system using the centralized management unit, that is capable of accommodating changes in data transmission simply and at low cost. The centralized management unit has an input-side interface connected to the facility equipment, an output-side interface for outputting the management data of the facility equipment, a storage section for storing a control program of the facility equipment, and an arithmetic processing section for controlling the facility equipment in accordance with an instruction of the control program. The storage section stores a first transmission program corresponding to the input-side interface and a second transmission program corresponding to an interface of the connection intermediating device. The arithmetic processing section obtains the management data from the facility equipment via the input-side interface in accordance with an instruction of the first transmission program and outputs the management data to the output-side interface in accordance with an instruction of the second transmission program.
