11.8.8 SETTINGS
The automatic system settings can take up to 1 minute once power is supplied; do not operate the remote control
during this time.
In the event that 1 remote control 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 control 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 remote control
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.)
Setting for 1 remote control group control
•
A maximum of 16 indoor units can be connected at the time of group control. (Do not connect the heat pump unit
with the cooling only unit.)
•
There are 2 methods for setting the group control address (A/C No.); an automatic and a manual setting method.
•
The A/C No. setting cannot be confirmed when using the automatic method.
•
To set each indoor unit's A/C No., use the manual setting method.
However, if the wall type indoor unit is connected, then manual setting is not possible.
■ Automatic setting
•
By switching ON the indoor unit's power supply with the DIP switch where the A/C No. is set to "01" (factory
setting), the A/C No. will be automatically set. (After activating the power for all indoor units, the automatic
setting takes approximately one minute.)
•
Once the A/C No. is automatically set, even when the power supply is switched OFF, the setting is stored.
To reset the A/C No. setting, follow the instructions for the "group control automatic address reset". Refer to
the item "Local setting" in the installation instruction manual that comes with the wired remote control for the
"group control automatic address reset" method.
* If the indoor unit's A/C No. DIP switch is not set to "01", the automatic setting cannot be reset.
■ Manual setting
•
The manual setting is performed using each indoor unit's printed circuit board DIP switch. (Refer to the
diagram below)
•
Set the DIP switch once the power supply for each indoor unit is switched OFF. When the power supply is
turned ON, the stored A/C No. is recalled.
•
To change the setting of the A/C No., turn OFF the power supply before resetting the DIP switch.
* Ensure that there is no redundancy in the A/C No. Any redundancy can cause faulty control.
* Ensure to set the A/C No. to "01" for 1 indoor unit.
