1-1. M-NET wiring configuration
(1) Types and maximum allowable length of M-NET transmission cables
The wiring diagram below shows a sample M-NET transmission wiring for a CITY MULTI system.
The maximum total line distance (centralized control and indoor-outdoor transmission lines) for each M-NET system is expressed
in the formula below. Observe the maximum length to ensure proper signal transmission to and from the connected equipments
over the M-NET transmission line.
If the maximum line length is exceeded, the M-NET signals will be attenuated, resulting in communication error and control
failure.
a+b+d+e(f) ≤500m a+b+c+g ≤500m e(f)+d+c+g ≤500m
The local remote controller cable length should be 10 m or shorter. The part that exceeds the 10 m limit should be included in the
maximum total line length of 500 m.
(A) Centralized control transmission line
The power supply distance for the centralized controller transmission line is expressed in the formula below.
This is the maximum length of the centralized control transmission line to which proper amount of power reaches. If the maximum
line length is exceeded, those equipments at the end of the transmission line may not receive enough power, resulting in
communication error and control failure.
a+b ≤200m a+b+c ≤200m
(B) Indoor-outdoor transmission line
The power supply distance for the indoor-outdoor transmission line is expressed in the formula below.
This is the maximum length of the indoor-outdoor transmission line to which proper amount of power reaches. If the maximum
line length is exceeded, those equipments at the end of the transmission line may not receive enough power, resulting in
communication error and control failure.
d+e(f) ≤200m g≤200m
The length of the local remote controller cable that exceeds the 10 m limit should be included in the maximum total line length of
500 m and in the power supply distance of 200 m.
NOTES
* Apply following precautions when using the K transmission converter (model PAC-SC25KAA; discontinued) and controlling the
M-NET model and K control model with the same controller.
Refer to the K transmission converter (PAC-SC25KAA) installation manual for details.
1Centralized controller address
Always set the controller address to “000”.
2Centralized controller function selects
Set the “K Converter Address” by using the “M-NET Settings” on the Initial settings screen.
3Indoor unit address
Set all M-NET model indoor units from the No.1 unit, then set the K control model addresses.
Indoor unit No.1 unit ~M-NET indoor unit max. address> K control indoor unit minimum address ~50
4K control model group No.
The minimum indoor address No. of that group becomes the group No. (Same for K control side local remote controller.)
5The remote controller address does not need to be included in the K-control unit group settings.

2. System with connection to an Expansion controller (system with 51 or more units)
• Refer to the PAC-YG50ECA Expansion controller Installation/Instructions Manual for how to set the IP address.
• The same M-NET address cannot be used twice in the same M-NET system that connects to the same PAC-YG50ECA
Expansion controller.
See section 1 “Standard configuration” for how to set the addresses for the equipments that are connected to the Expansion
controller within an M-NET system.
NOTES
* The DB No. of PAC-YG50ECA is found on the package box and the controller itself in the [DB No. : **] format.
Only the Expansion controllers with the same DB No. as the AG-150A can be connected to the AG-150A. Be sure to check the
DB No. before connecting the Expansion controller to the system.
If the DB numbers of the AG-150A and PAC-YG50ECA do not match, the software needs to be updated. Consult your dealer.
* Provide “one-point grounding” for the M-NET transmission line (centralized control system) by grounding the shield of the an
Expansion controller. (Class-D grounding)
Ground the indoor-outdoor transmission line in each outdoor unit refrigerant system.
* Set the centralized control switch (SW2-1) on the outdoor units on the M-NET line to ON.
(Refer to the outdoor unit Installation Manual for the details of the dipswitch settings.)
