*1. The automatic indoor/outdoor address
setup function is not available when multiple
HBs or any HS is connected to a given system.
(2) Cautions
1) ME remote controller and MA remote controller cannot both
be connected to the same group of indoor units.
2) No more than 2 MA remote controllers can be connected to
a group of indoor units.
When a PAR-CT01MA series, PAR-4"x"MA series, or PAR-
3"x"MA series ("X" represents 0 or later) is connected to a
group, no other MA remote controllers can be connected to
the same group.
3) When the number of the connected indoor units is as shown
in the table below, one or more transmission boosters (sold
separately) are required.
To connect two transmission boosters, connect them in par-
allel. (Observe the maximum number of connectable indoor
units that are listed in the specifications for each outdoor
unit.)
Number of transmission booster (sold separately) required
1 unit
25 - 50 units
The table above shows the number of transmission boost-
ers that is required by the system with four HBC controllers.
For each HBC controller added or subtracted, subtract or
add two indoor units.
4) Automatic address setup is not available if start-stop input
(CN32, CN51, CN41) is used for a group operation of indoor
units or when multiple indoor units with different functions
are grouped in the same group. Refer to the following

Maximum distance (1.25mm
L1 +L2+L3+L4 200m[656ft]
L1 +L2+L11+L12+L13 200m[656ft]
*If the power-supply distance exceeds the distance limit
of 200 meters, a transmission booster (PAC-SF46EPA-
G) is required.
2) Transmission line for centralized control
No connection is required.
3) MA remote controller wiring
Maximum overall line length
(0.3 to 1.25mm
m1 200m [656ft]
m2+m3 200m [656ft]
m4+m5 200m [656ft]
*1 70m [229 ft] for PAR-CT01MA series (single remote
controller only)
*To wire PAR-CT01MA series, PAR-4"x"MA series,
PAR-3"x"MA series ("X" represents 0 or later), and Sim-
ple MA remote controller, use a wire with a diameter of
