of their address.
2. No address setting is needed.

: When the System Controller is used, all the Dip SW5-1 at the outdoor units should be
set to "ON". * Dip SW5-1 remains OFF when only LM-AP is used.
: When the LM-AP is used together with System Controller, DipSW1-2 at the LM-AP should be
set to "ON".
: Change jumper from CN41 to CN 40 at outdoor control board will activate central transmission
power supply to TB7;
(Change jumper at only one outdoor unit when activating the transmission power supply
without using a power supply unit.)
Change jumper from CN41 to CN 40 at LM-AP will activate transmission power supply to LM-AP
itself;
Power supply unit is recommended to use for a system having more than 1 outdoor unit,
because the central transmission power supply from TB7 of one of outdoor units is risking that
the outdoor unit failure may let down the whole system controller system.
