Check method
On the remote controller (Wired remote controller, Central control remote controller) and the interface P.C.
board of the outdoor unit (I/F), a check display LCD (Remote controller) or 7-segment display (on the
outdoor interface P.C. board) to display the operation is provided. Therefore the operation status can be
known. Using this self-diagnosis function, a trouble or position with error of the air conditioner can be found
as shown in the table below.
Check code list
The following list shows each check code. Find the check contents from the list according to part to be
checked.
• In case of check from indoor remote controller: See “Wired remote controller display” in the list.
• In case of check from outdoor unit: See “Outdoor 7-segment display” in the list.
• In case of check from indoor unit with wireless remote controller: See “Sensor block display of receiving
unit” in the list.
AI-NET: Artificial Intelligence.
IPDU: Intelligent Power Drive Unit
: Lighting, : Flashing, : Goes off
ALT.: Flashing is alternately when there are two flashing LED.
SIM: Simultaneous flashing when there are two flashing LED.
