11-3. System configuration restrictions
11-3-1. Common restrictions for the CITY MULTI system
For each Outdoor/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.
*When a PAR-CT01MAU or PAR-40MAAU is connected to a group, no other MA remote controllers can be connected
to the same group.
*To wire PAR-CT01MAU, PAR-40MAAU, and PAC-YT53CRAU, use a wire with a diameter of 0.3 mm

[AWG22]
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/Heat source unit.
E) A maximum of 6 system controller are connectable to TB3 and TB7 of Outdoor/Heat source unit.
F) 4 System controllers or more are connectable when connecting to TB7 of the Outdoor/Heat source unit, if the
transmission power is supplied by the power supply unit PAC-SC51KUA.
*System controller connected as described in D) would have a risk that the failure of connected
Outdoor/Heat source unit would stop power supply to the System controller.
11-3-2. Ensuring proper communication power and the number of connected units for M-NET
In order to ensure proper communication among Outdoor/Heat source unit, Indoor unit, Lossnay, and Controllers, the trans
-
mission power situation for the M-NET should be observed. In some cases, Transmission booster should be used.
Taking the power consumption of Indoor unit as 1, the equivalent power consumption or supply of others are listed at Table
1 and Table 2.
Both the transmission line for centralized controller and indoor-outdoor transmission line must meet the conditions listed
below. (Both conditions a) and b) must be met.)
a) [Total equivalent power consumption] ≤ [The equivalent power supply]
b) [Total equivalent number of units (Table1)] ≤ [40]
Table 1 The equivalent power consumption and the equivalent number of units
*1 PWFY cannot be connected to PUMY model.
