display“--”, the eight-segment LED after decimal shows unit
sequence number, 0~F corresponds to 00~15 indoor unit.
• Clear error codes: Long press for 5S under error inquiry
mode to clear current error and history error, press any key
or no operation within 10S to quit error inquiry; press ON/
OFF to quit error inquiry directly and unit will be switched on
or switched off.
• Communication error: Communication with indoor unit is
abnormal for continuous 4 minutes, wired controller shows
error 07, if communication recovers, error will disappear
automatically.
• If indoor unit is using temperature sensor in wired controller,
temperature sensor of wired controller is short circuit or
open circuit for continuous 2 minutes, wired controller show
error 01.
• Other error pls refer to error list in indoor user manual.

18
Operation
Mode restriction function:
• If SW1-2 is on, mode restriction function valid. Mode key is

cannot be changed.
• Under mode restriction mode, mode cannot be changed by
mode key on wired controller, but mode can be changed
by other source, like remote controller send signal to wired
controller, central controller, change indoor mode directly by
remote controller etc.
• After changing dip switch, must power off and on again to
