For each Heat source 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;
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 Heat source unit.
E) Maximum 6 System controllers are connectable when connecting to TB7 of the Heat source unit, if the transmission
power is supplied by the Heat source unit.
F) 4 System controllers or more are connectable when connecting to TB7 of the Heat source 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 Heat source
unit would stop power supply to the System controller
11-3-1. Common restrictions for the CITY MULTI system
*If PAC-SC51KUA is used to supply power at TB7 side, no power supply need from Heat source unit at TB7, Connector TB3 itself will therefore have 32.
With the equivalent power consumption values in Table 11-3-1 and Table 11-3-2, PAC-SF46EPA can be designed into the air-
conditioner system to ensure proper system communication according to 11-3-2-A, B, C.
11-3-2-A) Firstly, count from TB3 at TB3 side the total quantity of Indoor units, ME remote controller, and System controllers.
counted as 2 indoor units, but MA remote controller(s) and PZ-41SLB are NOT counted.
11-3-2-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
or another controller with a built-in power supply,
such as PAC-YG50ECA,
is used to supply power at TB7 side, count from index TB3 side only.
11-3-2-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.
11-3-2. Ensuring proper communication power for M-NET
In order to ensure proper communication among Heat source 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 11-3-1 and Table 11-3-2.
System example
If the total quantity reaches 40, a PAC-SF46EPA should be set. In this case, Indoor units sized P72 and 96 are
B) Maximum 2 remote controllers for 1 Group;
*MA/ME remote controllers cannot be present together in 1group.
*To wire PAC-YT53CRAU, use a wire with a diameter of 0.3 mm

*1 AE-200A/AE-50A has a built-in function to supply power to the M-NET transmission line. The amount of power that an AE-200A or an AE-50A can supply is
equivalent to the power required by an MN converter (CMS-MNG-E) that is used for maintenance.
