2
(*1) This will not be displayed on indoor unit which Error Report Target (function setting 47 of indoor unit) is set "for administrator".
(*2) The System condition can change to (Trouble Level 1) by changing DIP SW (SET 4-1:OFF)
(*3) Even if power is reset, this Error cannot release. In Error release, you need to solving the problem and operate the push switch and a and apply
"Error reset" (F3-40) after power restart.
(*4) When one of outdoor unit on the multi connection detects these Error, the backup operation can activate by using of remaining outdoorunit(s)
Please check each trouble shooting, and read the caution before using the backup operation.
