1-1. General Cautions

Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiring
regulations, and guidance of each electric power company.
Wiring for control (hereinafter referred to as transmission ) shall be (50mm[1-5/8in] or more) apart from power source
wiring so that it is not influenced by electric noise from power source wiring. (Do not insert transmission and power

source wire in the same conduit.)
Be sure to provide designated grounding work to outdoor unit.
Give some allowance to wiring for electrical part box of indoor and outdoor units, because the box is sometimes removed
at the time of service work.
Never connect 100V, 208~230,460V power source to terminal block of transmission . If connected,electrical parts will

be burnt
Use

2-conductor

cable, the resultant poor transmitting and receiving will cause erroneous operations.

2-3. System Conguration Restrictions

2-3-1. Common restrictions for the CITY MULTI system

For each Outdoor unit, the maximum connectable quantity of Indoor unit is specified at its Specifications table.

A) 1 Group of Indoor units can have 1-16 Indoor units;
B) Maximum 2 remote controllers for 1 Group; (MA/ME remote controllers cannot be present together in 1group.)

C) 1 LOSSNAY unit can interlock maximum 16 Indoor units; 1 Indoor unit can interlock only 1 LOSSNAY unit.
D) Maximum 3 System controllers are connectable when connecting to TB3 of the Outdoor unit.
E) Maximum 3 System controllers are connectable when connecting to TB7 of the Outdoor unit, if the transmission

power is supplied by the Outdoor unit.

F) 4 System controllers or more are connectable when connecting to TB7 of the Outdoor unit, if the transmission

power is supplied by the power supply unit PAC-SC51KUA. Details refer to 2-3-3-C.
*System controller connected as described in D) and E) would have a risk that the failure of connected Outdoor
unit would stop power supply to the System controller.

2-3-2. Ensuring proper communication power for M-NET

In order to ensure proper communication among Outdoor unit, Indoor unit, LOSSNAY and Controllers, the transmission
power situation for the M-NET should be observed. In some cases, Transmission booster should be used. Taking the
power consumption index of Indoor unit sized P06-P54 as 1, the equivalent power consumption index and supply
capability index of others are listed at Table 2-3-1 and Table 2-3-2.

*If PAC-SC51KUA is used to supply power at TB7 side, no power supply need from Outdoor unit at TB7, Connector TB3 itself will therefore have 32.
Not applicable to the PUMY model.

Power supply unit

PAC-SC51KUA

With the equivalent power consumption values in Table 2-3-1 and Table 2-3-2, PAC-SF46EPA can be designed into the air­conditioner system to ensure proper system communication according to 2-3-2-A, B, C.
2-3-2-A) Firstly, count from TB3 at TB3 side the total quantity of Indoor units and ME remote controller, Timers and System
controllers.If the total quantity reaches 40, a PAC-SF46EPA should be set.In this case, Indoor unit sized P72, 96 is
counted as 7 Indoor units, but MA remote controller(s), LOSSNAY is NOT counted.
2-3-2-B) Secondly, count from TB7 side to TB3 side the total transmission power consumption index. If the total power consumption

reaches 32, a PAC-SF46EPA should be set.Yet, if a PAC-SC51KUA is used to supply power at TB7 side, count from
index TB3 side only.

2-3-2-C) Thirdly, count from TB7 at TB7 side the total transmission power consumption index, If the total power consumption reaches

6, a PAC-SF46EPA should be set.

2. M-NET CONTROL

The power to System controller (excluding LMAP03-U) is supplied via M-NET transmission line. M-NET transmission line
at TB7 side is called Central control transmission line while one at TB3 side is called Indoor-Outdoor transmission line.
There are 3 ways to supply power to the System controller .
A) Connecting to TB3 of the Outdoor unit and receiving power from the Outdoor unit.
B) Connecting to TB7 of the Outdoor unit and receiving power from the Outdoor unit.
C) Connecting to TB7 of the Outdoor unit but receiving power from power supply unit PAC-SC51KUA.

Maximum 3 System controllers can be connected to TB3.
If there is more than 1 Outdoor unit, it is necessary to
replace power supply switch connector CN41 with CN40
on one Outdoor unit.

Maximum 3 System controllers can be connected to TB7
and receiving power from the Outdoor unit.
It is necessary to replace power supply switch connector
CN41 with CN40 on one Outdoor unit.

When using PAC-SC51KUA to supply transmission
power, the power supply connector CN41 on the Outdoor
units should be kept as it is. It is also a factory setting.
1 PAC-SC51KUA supports maximum 1 AG-150A unit
due to the limited power 24VDC at its TB3.
However, 1 PAC-SC51KUA supplies transmission power
at its TB2 equal to 5 Indoor units, which is referable at
Table 2-3-2.
If PZ-52SF, Timers, System controller, ON/OFF controller
connected to TB7 consume transmission power more
than 5 (Indoor units), Transmission booster
PAC-SF46EPA is needed. PAC-SF46EPA supplies
transmission power equal to 25 Indoor units.

AG-150A*1 is recommended to connect to TB7 because it performs back-up to a number of data.
In an air conditioner system has more than 1 Outdoor units, AG-150A receiving transmission power through TB3 or TB7 on one of the Outdoor units would
have a risk that the connected Outdoor unit failure would stop power supply to AG-150A and disrupt the whole system.
When applying apportioned electric power function, AG-150A is necessary to connected to TB7 and has its own power supply unit PAC-SC51KUA.
Note: Power supply unit PAC-SC51KUA is for AG-150A.
*1: AG-150A is an example model of system controllers.

Rotary switch

In order to constitute CITY MULTI in a complete system, switch
operation for setting the unit address No. and connection No. is
required.

À Address No. of outdoor unit, indoor unit and remote controller.

The address No. is set at the address setting board.
In the case of R2 system, it is necessary to set the same No. at the
branch No. switch of indoor unit as that of the BC controller
connected. (When connecting two or more branches, use the lowest
branch No.)

Á Caution for switch operations

 MA remote controller

¥ Be sure to shut off power source before switch setting. If operated with power source on, switch can

not operate properly.

¥ When connecting only one remote controller to one group, it is always the main remote controller.
When connecting two remote controllers to one group, set one remote controller as the main remote controller

and the other as the sub remote controller.

¥ No units with identical unit address shall exist in one whole air conditioner system. If set erroneously,

the system can not operate.

¥ The factory setting is Main .
