Is auto address setting complete?
Is there an auto address setting error (Is the outdoor unit showing
an alarm)?
Conduct checks prior to auto address setting.
Is that indoor unit under group control?
Are there any indoor units with their power off in the remote
control group's wiring?
Are nine or more indoor units connected in one remote control
group's wiring?
Was the remote control group's wiring changed after auto address
setting was complete? Alternatively, were group settings changed
in the remote control detailed settings mode?
No main unit in the remote control group's wiring? Re-execute auto address setting.
Are the CHK pin and TEST pin on the indoor unit control board
short-circuited?
Is the wireless remote controller connected to on the indoor unit's
control PC board?
Disconnect the connector mentioned above on the PC board of the
indoor unit control PC board, and see whether the E01 goes off after
several minutes. (When doing so, if two remote controllers are
being used and the wireless remote controller is the main remote
controller, set the other remote controller as the main.)
Replace wireless remote control parts including wiring.
Is the LED blinking on the indoor unit's control PC board?
The nonvolatile memory (EEPROM) on the indoor unit's control PC board is either not
installed, improperly installed or the nonvolatile memory is faulty. Correct this or after
replacing the nonvolatile memory, write model data to it in the remote control detailed
settings mode.
Is there a short, miswiring, disconnection, wrong contact or
grounding in the remote control's wiring?
