11. M-NET CONTROL
11-4-3. System examples
Factory setting
Original switch setting of the heat sources, indoors, controllers, LM-AP, and BM ADAPTER at shipment is as follows.
• Heat source unit
• Indoor unit
• BC controller
• ME remote controller : Address: 101
• LM-AP
• BM ADAPTER
• AE-200A/AE-50A/EW-50A : Address: 000, CN21: ON (Jumper)
Setting at the site
• DipSW5-1(Heat source) : When the System Controller is used, all the Dip SW5-1 at the heat source units should be
• DipSW1-2(LM-AP)
• CN40/CN41
• CN21(AE-200A/AE-50A/EW-50A)

*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. Heat source 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.
2. No address setting is needed.
3. For a system having more than 32 indoor unit (P06-P54), confirm the need of Booster at 11-3 "System configuration
restrictions".
4. Indoor units should be set with a branch number.
5. Address setting is required if a sub BC controller is connected.

: Address: 000, CN41: ON (Jumper)
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 heat source control board will activate central transmission
power supply to TB7;
(Change jumper at only one heat source unit when activating the transmission power supply without
using a power supply unit.)
Change jumper from CN41 to CN 40 at LM-AP/BM ADAPTER will activate transmission power
supply to LM-AP/BM ADAPTER itself;
Power supply unit is recommended to use for a system having more than 1 heat source unit,
because the central transmission power supply from TB7 of one of heat source units is risking that
the heat source unit failure may let down the whole central control system.
: Activates the power supply to M-NET transmission line from AE-200A/AE-50A/EW-50A
(CN21: ON (power supplied), OFF (power not supplied)
