11 MAINTENANCE AND UPKEEP
11.1 Failure information and code
In case the unit runs under abnormal condition, failure protection code will display on both control panel and wired controller, and the
indicator on the wired controller will flash with 1Hz. The display codes are shown in the following table:
Table11-1 65KW and 110KW
