2. M-NET CONTROL
2-4-3. System examples
Original switch setting of the heat sources, indoors, controllers and LMAP at shipment is as follows.
• Heat source unit : Address: 00, CN41: U (Jumper), DipSW2-1: OFF
• Indoor unit: Address: 00
• BC controller: Address: 00
: Address: 101
• LMAP : Address: 247, CN41: U (Jumper), DipSW1-2: OFF
• DipSW2-1(
Heat source
): When the System Controller is used, all the Dip SW2-1 at the heat source 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 Controller, DipSW1-2 at the LMAP
should be set to "ON".
• CN40/CN41
: 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 LMAP will activate transmission power supply to LMAP
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.
2-4-3-1. MA remote controller, Single-refrigerant-system, No System Controller
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 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.
