2. M-NET CONTROL
2-4-3-1. MA remote controller, Single-refrigerant-system, No System Controller
Original switch setting of the outdoors, indoors, controllers and LMAP at shipment is as follows.
Outdoor unit : Address: 00, CN41: U (Jumper), DipSW2-1: OFF
Indoor unit : Address: 00
ME remote controller : Address: 101
LMAP : Address: 247, CN41: U (Jumper), DipSW1-2: OFF
DipSW2-1(Outdoor) : When the System Remote Controller is used, all the Dip SW2-1 at the outdoor units should be
set to "ON".
* Dip SW2-1 remains OFF when only LMAP03U is used.
DipSW1-2(LMAP) : When the LMAP is used together with System Remote Controller, DipSW1-2 at the LMAP
should be set to "ON".
CN40/CN41 : 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.
