1 Introduction
Special features of Mitsubishi Electric Corporation’s “Centralized Controller AG-150A,” “Centralized Controller
AG-150A-A,” “Centralized Controller GB-50ADA-A,” and “Centralized Controller GB-50ADA-J” are that a PC
connected to a LAN can be used to monitor the operation condition of air conditioners and perform air
conditioner operations.
The document explains the procedures to monitor the status of and to operate the centralized controller on the
Web browser are described.
Hereinafter, Centralized controller AG-150A, AG-150A-A, GB-50ADA-A, and GB-50ADA-J, unless otherwise
specified, will be called "AG-150A".
Note: License of "Web Monitor" or "Basic License Pack" is necessary to use the web browser (to operate or monitor the air
conditioners). Some licenses are necessary depending on the functions to be used. Register the license key on the LCD
screen or on the registration screen.
Note: A one-day license key can be registered on the LCD screen that allows the user to use the "Web Monitor" only on the day of
the registration (not applicable to GB-50ADA-A and GB-50ADA-J). Use this license key to use the initial setting browser, or
in any other situations when a temporary license key "Web Monitor" is necessary.
Note: Use a security device such as a VPN router when connecting the AG-150A to the Internet to prevent unauthorized access.
Note: "Booster unit" and "Water HEX unit" are referred to as "Air To Water (PWFY)".
Note: GB-50ADA-A and GB-50ADA-J cannot be connected to the Expansion Controller (PAC-YG50ECA). Settings or displays of
the Expansion Controller cannot be made on the GB-50ADA-A and GB-50ADA-J.

2 Setting the Operating Environment
PC settings and web browser settings required for using a web browser to monitor air conditioner units and
perform operations are explained in the following pages.
2-1 Setting the PC IP Address
Set an IP address on the PC that enables AG-150A to connect via a web browser. For instance, if the
AG-150A IP address is [192.168.1.1], the PC IP address will need to belong to the same system
[192.168.1.101].
If the AG-150A is connected to an existing LAN, ask the LAN administrator to decide what PC IP address to
use.
Note: When using a AG-150A dedicated LAN, it is recommended that the AG-150A main unit be given an IP address
within the range [192.168.1.1] - [192.168.1.40] and the PCs that will be connected to the AG-150A be given an IP
address within the range [192.168.1.101] - [192.168.1.150]
(1) Click on [Control Panel] under [Start] to open the Control Panel.
(2) In the Control Panel window, double click [Network and Dial-up
Connections] and the Network and Dial-up Connections window will
open. Double click on [Local Area Setting] and the [Local Area
Connection Status] dialog will open. Click [Properties].
(3) In the [Local Area Connection Properties] dialog, click [Internet
Protocol] to select it and click the [Properties] button.

(4) In the [Internet Protocol (TCP/IP) Properties] dialog, click [Use the
following IP address] and enter the IP address (for example,
“192.168.1.101”) that you want to set in the IP address field.
You normally set [255.255.255.0] as the subnet mask.
Note: Ask your LAN administrator to provide the IP addresses and subnet
mask.
(5) Click the [OK] button to close this dialog, and then close the other
open dialogs to complete the network setting.

3-1-2 Encrypting the communication data and login on the AG-150A
AG-150A can encrypt communication data using HTTPS (SSL).
When connecting the AG-150A to the LAN that can be accessed by the general public, it is recommended
that the following settings be made so that the units are monitored and controlled on the encrypted Web page.
Note: Depending on the operating system or the version of Java, HTTPS encrypted messages may not be handled correctly. If
this happens, use a HTTP connection to monitor and control the units as noted in the section above.
(1) Go to [Tools]->[Internet Options]->[Advanced], and make the
following settings.
Item Checkbox setting
Use SSL 2.0 Uncheck the box.
Use SSL 3.0 Check the box.
Use TLS 1.0 Uncheck the box.
Do not save encrypted pages to disk Check the box.
Note: Some of the settings may have different names depending on the Web
browser version.
(2) Click on [Java] in the Control Panel, and make the settings for the
items under [Security] in the [Advanced] tab.
Item Checkbox setting
Use SSL 2.0 compatible Client Hello format Uncheck the box.
Use SSL 3.0 Check the box.
Use TLS 1.0 Uncheck the box.
Note: Some of the settings may have different names depending on the Java
version.
(3) Prefix the Web address with [https], enter the address, and hit the
[Enter] (Return) key on the keyboard.
https://[ IP Address of the AG-150A]/index.html
Note: For example, type “https://192.168.1.1/index.html” if the AG-150A IP
address is [192.168.1.1].
If the security alert is disabled as described in the note in the
following and the subsequent sections, encrypted date
communication will begin, and the Login screen will appear. If the
security alert has not been disabled, take the following procedures.

(4) If the security alert has not been disabled, after entering the web address and hitting the Enter (Return) key,
a security alert message will alert asking if you want to proceed. This is because the AG-150A uses the
self-authentication system. Click [Yes] and proceed.
Note: Disable the security alert that appears every time the browser is opened, take the following two steps:
1) Register the security certificate and
2) Change the Web browser's option settings
To register the security certificate, click the [View Certificate] button on the security alert window to display the certificate,
click on the [Install Certificate] button, and add the certificate to the Trusted Root Certification Authorities store. Just follow the
prompts of the Import Wizard.
Go to [Tools]->[Internet Options]->[Advanced], and make the following
settings for the Web browser.
Item Checkbox setting
Warn about invalid site certificates Uncheck the box.
(5) A Java security alert message will appear after you click [Yes] in
step (4) above, click [Yes] again to proceed.
Note: To disable the security alert message that appears every time the
browser is opened, check the check box next to [Always trust content
