Check method
On the 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 (including hot water module) can be found as shown in the table below.
