NOTES
* The BAC-HD150 and the type of controllers that connect to the expansion controller via the LAN (e.g., AG-150A) each have a DB No.
This 2-digit number is indicated on the package box and the controller. ([DB No.:**])
Controllers with different DB No. cannot be connected to each other. Be sure to check the DB No. of each controller to be connected.
Connection of two or more controllers that have different DB No. requires a controller software version update. Consult your dealer for
how to update the software.
Label contents
* Use a switching HUB.
* Provide "one-point grounding" for the M-NET transmission line (centralized control system) by grounding the shield of each
expansion controller.
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.)
