2-3. System configuration restrictions
2-3-1. Common restrictions for the HYBRID 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.
*When a PAR-31MAA is connected to a group, no other MA remote controllers can be connected to the same group.
C) 1 LOSSNAY unit can interlock maximum 16 indoor units; 1 indoor unit can interlock with only 1 LOSSNAY unit.
D) Maximum 3 System controllers are connectable when connecting to TB3 of the outdoor unit.
E) Maximum 6 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, a transmission booster should be used. Taking the power
consumption of indoor unit sized P15-P140 as 1, the equivalent power consumption or supply 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.
With the equivalent power consumption values in Table 2-3-1 and Table 2-3-2, PAC-SF46EPA can be designed into the
air-conditioner 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, ME remote controller, and system controllers.
If the total quantity reaches 40, a PAC-SF46EPA should be installed. In this case, indoor units sized P200 and 250 are
counted as 2 indoor units, but MA remote controller(s) and PZ-60DR-E are NOT counted.
2-3-2-B) Secondly, count from TB7 side to TB3 side the total transmission power consumption. If the total power consumption
reaches 32, a PAC-SF46EPA should be installed. Yet, if a PAC-SC51KUA is used to supply power at TB7 side, count from
TB3 side only.
2-3-2-C) Thirdly, count from TB7 at TB7 side the total transmission power consumption, If the total power consumption reaches
6, a PAC-SF46EPA should be installed.
