  The automatic system settings can take up to 1 minute once power is supplied; do not operate the remote 
controller during this time. 
  In the event that 1 remote controller group control is not used, do not set up the group control address (A/C No.).

  Once the wires are connected to 1 remote controller group control and power is supplied to the indoor unit, the 
A/C No. is automatically set. To stop group control use, follow the directions below and clear the A/C No. that was 
automatically set after disconnecting the wires for group control. If it is not cleared then the wired controller will not 
show any display.
