11. M-NET CONTROL

11-3. System Configuration Restrictions

11-3-1. Common restrictions for the CITY MULTI system
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;
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
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
11-3-2. 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.

*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.
*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.
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.
If the total quantity reaches 40, a PAC-SF46EPA should be set. In this case, Indoor units sized P72 and 96 are
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.
