RAV-SM800AT-E LED display when SW800 : Bit 1, 2, 3, 4 OFF

•When multiple errors are detected, the latest error is displayed.

•While LED displays 〇 (go on), there is the main cause of error in control at CDB side and it stops abnormally.

•While LED displays ◎ (flash), there is the main cause of error in control at IPDU side and it stops abnormally.

•For an error in case thermo operation, the communication is interrupted on the serial circuit. If continuing the case thermo operation, serial sending to the indoor unit is interrupted and a serial communication error is output.
