1. Specifications
*1 Not for use with a generic DC power supply device. Use the power supply unit for transmission line (PAC-SC51KUA etc.) by Mitsubishi.
*2 "Power consumption Coefficient" is a coefficient to calculate the relative power consumption of the devices that receive power through
the M-NET transmission line.
Refer to the note at the end of Chapter 4 "System diagram."

1. System configuration
*1 The power consumption coefficient of the Touch Controller is 4 and that of an indoor unit is "1"*, which means that each TC-24A unit
consumes power equivalent to four indoor units. (*Indoor units receive power through the M-NET transmission line to maintain communica-
tion during power failure.) Refer to the CITY MULTI DATABOOK for details. The total power consumption of the connected devices should
not exceed the capacity of the power supply units.
The Design Tool by MITSUBISHI ELECTRIC allows its user to design air conditioning systems easily.
TC-24A is compatible with the Design Tool version 3.71 or later.
The Touch Controller can be connected to either TB7 or TB3.
When connected to TB3, no power supply units are required.

●
The figure at left only shows the
transmission line connections.
Power supply lines are omitted.
●
Provide a single ground point
(class D) by grounding the
shield wire of the M-NET
centralized controller transmis-
sion cable at one of the power
supply units. Provide a ground
point for the indoor-outdoor
transmission cable for each
outdoor unit
●
Make sure that the centralized
control switch (SW2-1) on the
outdoor unit connected to the
M-NET cable is set to ON.
Refer to the outdoor unit
Installation Manual for detailed
information about dip switch
settings.
