*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. No address setting is needed.
2. For a system having more than 32 indoor unit (P15-P140), confirm the need of Booster at 2-3 "System configuration
restrictions".
3. Indoor units should be set with a branch number.
4. Address setting is required if a sub BC controller is connected.
: Address: 00, CN41: U (Jumper), DipSW2-1: OFF
: Address: 00
: Address: 00
: Address: 247, CN41: U (Jumper), DipSW1-2: OFF
: Address: 00
: 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 LMAP02-E is used.
It is also possible to connect Indoor unit sized P100-P140 with 1 port (set DipSW 4-6 to OFF).
: When the LMAP is used together with System Controller, DipSW1-2 at the LMAP
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 LMAP will activate transmission power supply to LMAP
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.
