*1 For wireless R/C and signal receiver unit (SRU), channel 1, 2 and 3 are selectable and should be set to same channel.
NOTE:
1. Outdoor units OC and OS in one refrigerant circuit system are automatically detected.
OC and OS are ranked in descending order of capacity. If units are the same capacity, they are ranked in ascending order
of their address. (Only a single outdoor unit can be connected to a HYBRID CITY MULTI system.)
2. No address setting is needed.
3. For a system having more than 32 indoor units (P15-P140), check the need of a booster at 2-3 "System configuration
restrictions".
4. Indoor units should be set with a branch number.
5. When a PAR-31MAA is connected to a group, no other MA remote controllers can be connected to the same group.

: Address: 000, CN41: ON (Jumper)
: When the system controller is used, all the Dip SW2-1 at the outdoor units should be set to
"ON". * Dip SW2-1 remains OFF when only LM-AP is used.
: When the LM-AP is used together with the 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.)
Changing jumper from CN41 to CN 40 at LM-AP will activate transmission power supply to
LM-AP itself;
A power supply unit is recommended for use in a system having more than 1 outdoor unit,
because the central transmission power supply is from TB7 of one of the outdoor units, risking
that the outdoor unit failure may let down the whole system controller system.
