*1. If a given address overlaps any of the addresses that are assigned to other units, use a different, unused address within the setting
range.
*2. To set the outdoor unit address or the auxiliary outdoor unit address to "100," set the rotary switches to "50."
*3. To set the ME remote controller address to "200," set the rotary switches to "00."
*4. Some models of indoor units have two or three control boards.
Assign an address to the No.1, No. 2, and No. 3 control boards so that the No. 2 control board address equals the No. 1 control board
address plus 1, and that the No. 3 control board address equals the No. 1 control board address plus 2.
*5. No address settings are required for units in a system with a single outdoor unit (with some exceptions).
Address setting is required if two or more main HBC controllers and a sub HBC controller are connected.
*6. If a given address overlaps any of the addresses that are assigned to other units, use a different, unused address within the setting
range.

rest of the indoor units in the same group.
In a system with two or more HBC controllers, make the
settings for the indoor units in the following order.
(i) Indoor unit to be connected to the main HBC controller 1
(ii) Indoor unit to be connected to sub HBC controller 1
(iii) Indoor unit to be connected to the main HBC controller 2
(iv) Indoor unit to be connected to sub HBC controller 2
Make the settings for the indoor units in the way that the for-
mula "(i) < (ii) < (iii) < (iv)" is true.
