  • Page 7: Power Supply Function To The M-Net Transmission Line

    BAC-HD150 has a built-in function to supply power to the M-NET transmission line. (power supply coefficient: 6) When power is supplied from BAC-HD150, the total power consumption coefficient of the system controller and M-NET remote controller to which BAC-HD150 supplies power (See table 1) should not exceed the power supply coefficient of BAC-HD150, which is six.

  • Page 10: System In Which Bac-Hd150 Is Connected To The Expansion Controller

    • The same M-NET address cannot be used twice in the same M-NET system that connects to the same PAC-YG50ECA. 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.

  • Page 11: Restrictions For Using Bac-Hd150 In Combination With Other Controllers

    Note that the number of connectable controllers and compatible software versions are limited. If the software version is not compatible, update the software version of the controllers. Unless AG-150A and/or PAC-YG50ECA support the dual set point function, BAC-HD150 is not also available for the dual set point function (AV_xxxx24-28).

  • Page 12: Setting M-Net Address For Various Devices

    Refer to the K-transmission converter Installation manual for details. ① Be sure to set the BAC-HD150 address to "000." ② Be sure to set the K-control air conditioning unit connection setting on the BAC-HD150 to Yes (set via the Setting Tool).
  • Page 13 * Main and sub system controllers (M-NET) BAC-HD150 can only be used as the main system controller, but not as a sub system controller.  Main system controller (Main SC) Main SC refers to a controller that controls all other system controllers including the units they control. If a given system has only one system controller, that controller becomes the main SC.

  • Page 15: M-Net Transmission Line Length

    4-2. M-NET transmission line length • Connect the BAC-HD150 to the transmission line for centralized control (TB7 on the outdoor unit). • There should only be one power supply source within a single transmission circuit. The factory setting is that power is not supplied from the BAC-HD150.

  • Page 16: Installation

    4-3. Installation • Leave enough space around the unit to allow for an installation/uninstallation of the cover. (The amount of space needed is shown in the figure below.) • Screw down the cover with M4 screws as shown in the figure below. Be sure to fix the four corners to prevent it from falling.

  • Page 17: Wiring Connections

    Use a bipolar breaker (2P2E) with a minimum contact distance of 3 mm ( in.). • Install a breaker for each BAC-HD150 so that turning off the power to one BAC-HD150 will not affect the rest of the devices in the system.

  • Page 20: Connecting The Lan Cable

    5-4. Connecting the LAN cable • Make sure that the LAN cable is long enough to reach the LAN1 and LAN2 connectors on the BAC-HD150. Leave the LAN cable disconnected until all the initial settings for the BAC-HD150 (IP address setting etc.) have been completed.

  • Page 21: Making The Initial Settings

    CAUTION • Install the LAN cable before installing the unit, and route the cable in the same way as the M-NET transmission lines. • Connect the BAC-HD150 to a private network. Use a security device such as a VPN router when connecting to the Internet. (Without a proper security measure in place, the air conditioning system is vulnerable to access from unauthorized users.)
