11.8.8 SETTINGS
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.).
The wired remote control will not display when the settings for the A/C No. are set to a value other than “01”.
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.
•
Instructions on clearing the A/C No. after automatic setup
Turn OFF the indoor unit power supply → Using the DIP switch set the A/C No. to “16” → Turn ON the power
supply of the indoor unit → After approximately 1 minute, turn OFF the power supply to the indoor unit → Set
the DIP switch for the A/C No. to “01”.
(The next time the power supply is turned ON, the A/C No. will be cleared.)
