Note
Request codes 103 to 105 indicate error histories of both indoor and outdoor units.
As only four digits can be displayed at one time the software version number is displayed in two halves.
Enter code 190 to see the first four digits and code 191 to see the last four digits.
For example software version No. 5.01 A000, when code 190 is entered 0501 is displayed, when code 191 is entered A000 is displayed.
