2-3. System configuration restrictions
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) System controller is 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-B.

Table 2-3-2 The equivalent power supply
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.
2-3-2-A) If the total power consumption reaches 12, a PAC-SF46EPA should be set.
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.
