indoor unit and the outdoor unit. Therefore, you must
set it to operate the air conditioner properly.

SW01 and SW02.
The MAIN address from '00' to '99' should differ from
each other.
 Check the indoor unit address on the plan that you are
to install and set the address according to the plan.
Note You may not need to set MAIN address if you
selected Auto Address Setting from the outdoor
unit: see details on the outdoor unit installation
manual.
