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.
