A remote control device configured communicate with an air conditioner or a heat pump includes a touch panel having an electrode unit, a liquid crystal display, and a casing accommodating the touch panel and the liquid crystal display. The casing has a back surface part and a front surface part. The liquid crystal display is disposed to overlap the touch panel as seen from a front surface part side. The electrode unit has a first electrode section to detect a touched position, and a second electrode section that may function as an antenna to perform wireless communication with another communication device. The first and second electrode sections are configured and arranged to be nearer to the front surface part than to the back surface part inside the casing, and to be disposed so as not to overlap with each other as seen from the front surface part side.

Remote control device

In an air conditioner, one of a linkage mode or a non-linkage mode is selected by a user as a control mode of an external device. In the air conditioner, when the linkage mode is selected, on/off control of the external device by using a human detection sensor is permitted during operation, whereas on/off control of the external device by using the human detection sensor is inhibited during suspension of operation. In the air conditioner, when the non-linkage mode is selected, on/off control of the external device by using the human detection sensor is always permitted, irrespective of whether the air conditioner is in operation or not.

Air conditioner

In an air conditioner, an auxiliary circuit configured to prevent a current flow in a power supply wiring in an operation stop period and to determine whether to adapt an outdoor unit to a unit that is able to transition to a standby mode, is provided on the power supply wiring.

A control device is configured to control an air conditioner that includes an air conditioner outdoor unit and an air conditioner indoor unit. The control device includes a microcomputer and a storage element. The microcomputer causes a signal to be transmitted and received between an outdoor communication unit of the air conditioner outdoor unit and an indoor communication unit of the air conditioner indoor unit. The storage element stores specific information in response to command from the microcomputer. The microcomputer causes the storage element to store operation information including a state of transmission and reception of the signal of the air conditioner at a constant time interval.

Control device

After the power source to the control substrate is turned on, power is supplied to the compressor driver and the fan driver. Then, when it is determined that an indoor unit is in operation, the compressor driver and the fan driver are operated. Meanwhile, when it is determined that the indoor unit is not in operation, after the lapse of ten minutes or twenty minutes under a predetermined setting, the power to the compressor driver and the fan driver is cut. When the operation of the indoor unit is started again, power is supplied to the compressor driver and the fan driver.

Load driving device, outdoor unit of air conditioner, and driving method of load

A control device includes a microcomputer and a storage element. The microcomputer is configured to execute an inspection operation mode in which an air conditioner is operated in inspection process in a manufacturing site, and a normal operation mode in which the air conditioner is operated at an installation site. When the operation state of the air conditioner fails to satisfy predetermined conditions, the microcomputer is configured to confirm that there is an error, and abnormally stop the air conditioner. When the air conditioner is abnormally stopped, the microcomputer is configured to cause the storage element to store predetermined operation information obtained during a period until abnormal stoppage of the air conditioner and to store the operation mode being executed at the time of occurrence of the error in the air conditioner.

Air conditioner control device

An outdoor unit includes an outdoor unit control circuit, an inverter substrate and a compressor. Periodic communication showing the operating condition of the inverter substrate is set from the inverter substrate to the outdoor unit control circuit. Thus, when the communication is performed normally, the drive of the compressor is changed to a power saving process according to the necessity of the power consumption and the operating condition of the inverter substrate. When the communication is defective, the power-on reset is done to the inverter substrate.
