 Group control
In a group control, a remote controller can control up to maximum 8 units.
• For wiring procedure and wiring method of the individual line (Identical refrigerant line) system, refer to "Electric
wiring" in this Manual.
• Wiring between indoor units in a group is performed in the following procedure.
Connect the indoor units by connecting the remote controller inter-unit wires from the remote controller terminal
blocks (A/B) of the indoor unit connected with a remote controller to the remote controller terminal blocks (A/B)
of the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual attached to the outdoor unit.
 Changing the time before the Filter Sign lights up
The time before the Filter Sign lights up can be changed according to the installation conditions.
* Adjust this setting for the header unit.
• Select [01] in step 3 on page 70.
• Select a value from the table on the below in step 4 on page 70 according to the preferred time before the
Filter Sign lights up.

 For better heating performance
When it is hard to become hot due to the location of the indoor unit, room structure, etc., you can raise the detect
temperature for heating. It is recommended that you use a circulator or the like to circulate warm air around the
ceiling.
• Select [06] for CODE NO. in Step 3 on page 70.
• Select CODE NO. from the following table in Step 4 on page 70:

Shift value
* In addition to the above detect temperature shift value, the own detect temperature shift value (Heat: 2.5 °C,
Cool: -2.0 °C) is set for the Air to Air Heat Exchanger with DX coil unit in order to intake enough outdoor air. This
setting does not need to be changed, but if you want to change the setting, contact our Customer Support Center.
