2-4-3. System examples
Original switch setting of the outdoors, indoors, controllers, LM-AP and BM ADAPTER at shipment is as follows.
• Outdoor unit
: Address: 00, CN41: ON (Jumper), DipSW5-1: OFF
• Indoor unit
: Address: 00
• BC controller
: Address: 00
• BM ADAPTER
•
AE-200E/AE-50E/EW-50E
: Address: 000, CN41: ON (Jumper)
• DipSW5-1(Outdoor)
: 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.
• DipSW4-6(BC controller) : Set DipSW 4-6 to ON at BC controller, in case of connected Indoor unit sized P100-P140 with 2 ports.
It is also possible to connect Indoor unit sized P100-P140 with 1 port (set DipSW 4-6 to OFF).
• DipSW1-2(LM-AP)
: When the LM-AP is used together with System Controller, DipSW1-2 at the LM-AP
should be set to "ON".
• CN40/CN41
• CN21
(AE-200E/AE-50E/EW-50E)
: 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/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 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.
: Activates the power supply to M-NET transmission line from AE-200E/AE-50E/EW-50E
(CN21: ON (power supplied), OFF (power not supplied)
2-4-3-1. MA remote controller, Single-refrigerant-system, No System Controller
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.
2. No address setting is needed.
3. For a system having more than 32 indoor unit (P15-P140), confirm the need of Booster at
2-3 "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.
6. When a PAR-31MAA(E) is connected to a group, no other MA remote controllers can be connected to the same group.
