Description
High temp. error was detected in outdoor IGBT built-in temp. sensor (TH).
There is heat unit which was been detected water-shortage in 1 system.
(
←
Heat unit detected.)
There is abnormally stopped indoor unit which was been detected water-overflow
in 1 system. (
←
Indoor unit detected.)
Liquid back operation was judged from refrigerant cycle status.
Outdoor suction temp. sensor (TS1) continuously and repeatedly detected high
temperature over standard value.
High temp. error was detected in outdoor discharge temp. sensor (TD2).
High temp. error was detected in outdoor discharge temp. sensor (TD3).
Refrigerant cycle error was detected in heating operation.
High pressure (Pd) sensor detected pressure over standard value.
