NOTES!
To use multiple indoor units in parallel, make sure to change the setting of address code before
installation and guarantee that the address code of each indoor unit must be different (The address code is
located on the mainboard of indoor unit). If wired controller is used, make sure to dial the address code of
wired controller to the position same as the address code on corresponding indoor unit. (The address code of
wired controller is located on the back of wired controller)
The default setting of address dial-up code is 0000 and the address is 1 (See above for the position of dial
lever).

The dial-up value of address code is set in binary system. The dial-up value is "0" when the lever is dialed
to "ON" end; the dial-up is "1" when the lever is dialed to numerical end on opposite side. For number 4~1 on
the address code, the dial-up #4 refers to high bit and the dial-up 1# refers to low bit.
