miss-wiring between communication cable and power cable.
■
3. If error code E101 or E185 is displayed on indoor unit LED, check communi-
cation wire and power wire connection.
■
4. If error code E460 is displayed on outdoor unit LED, AC power line could be
connected to outdoor communication terminal, F1 & F2. So check the wiring
not only communication line but also power line.

units display a error code. In this case, correction at the wrong point could
solve all indoor unit error display.
