4-2-2 Configuring the System Configuration Settings
In the System Configuration Settings menu, set the use or non-use of PAC-YG50ECA Expansion Controller,
connection target, M-NET settings, and external input settings.
Note: When connecting multiple AG-150A controllers by connecting an Expansion Controller, all controllers must have the same
system configurations.
4-2-2-1 Setting the Expansion Controller Connection Setting
In the M-NET Settings menu, set the use or non-use of PAC-YG50ECA Expansion Controller and connection
target settings.
(1) Select from "Do not use" or "Use" to set the use or non-use of an Expansion Controller.
Note: Before setting the Expansion Controller setting to "Use," make sure that the Expansion Controller is connected to the LAN.
The settings made without the Expansion Controller being connected may not be saved (M-NET settings, external input
settings, group settings, LOSSNAY interlock settings etc., which are saved on the Expansion Controller side.)
(2) If "Use" is selected for the Expansion Controller setting, an IP
address input field will appear under "Access Point Settings."
Enter the IP address that is assigned to the Expansion Controller
here.
When connecting two Expansion Controllers, first click [EC1]
and enter the IP address for the first Expansion Controller system, and then click [EC2] to enter the IP
address for the second Expansion Controller system.
Note: Set the IP address for the Expansion Controller itself on the Expansion Controller unit.
(3) After the Expansion Controller connection setting or the IP address of the Expansion Controller was
changed, click the [Save] button and restart the AG-150A by following the messages on the screen. Make
the M-NET settings and external input settings after the system has been restarted.
Note: After connecting the Expansion Controller, check that the database number (DB No.) on the controller itself and the data base
number of the Expansion Controller match. If they do not, consult your dealer for software upgrade.
Note: To change the settings for the external input settings (or any other settings that are saved on the Expansion Controller side)
after the M-NET settings have been made, restart the controller and change the settings with the Expansion Controller
properly being connected to the system.
Note: To change the M-NET settings and external input settings in a system to which an Expansion Controller (PAC-YG50ECA) is
connected, be sure to change the settings with the Expansion Controller properly connected to the system. These settings
are stored on the Expansion Controller.
4-2-2-2 M-NET Setting
In M-NET Setting, set the AG-150A M-NET address, whether or not a K-Control unit is present and which
machines send the prohibited controller command.
(1) Enter the AG-150A M-NET address in the [M-NET Address] field. Normally you should enter [0].
(2) When K-Control air conditioners are connected, click [Used] in the [K-Control Units] field and enter the
M-NET address of K transmission converter in the [K Converter Address] field.
(3) If prohibited controller (prohibiting local operation) has been set, this setting determines the scope of this
setting s control, i.e. operation is prohibited for both the remote control and subordinate system controllers,
or just for the remote control. Click [SC/RC] when you want prohibited controllers to include both
subordinate system controllers and the remote control, or click [RC only] when you only want to prohibit
operation on the remote control.
Note: Normally, you should select [SC/RC].
