Air conditioner

摘要

A multi-connection air conditioner is caused to smoothly resume the operation thereof after an electric power recovery without using a nonvolatile memory device such as an EEPROM. An operation power source is backed up by a battery on remote controllers (2, 3), and the remote controllers thus transmit a periodic transmission signal containing an instructed operation mode at a predetermined time interval. When operation resuming means receives the periodic transmission signal from the remote controller while the indoor units (A, B) are stopped after an electric power recovery, If an Instructed operation mode is a manual mode, the operation resuming means resumes the operations of the outdoor unit (1) and a corresponding indoor unit upon a first periodic transmission signal, and alternatively if the instructed operation mode is an automatic mode, the operation resuming means resumes the operations of the outdoor unit and the corresponding indoor unit upon a second periodic transmission signal. <IMAGE>
