1 Introduction
A special feature of Mitsubishi Electric Corporation’s “Centralized Controller AG-150A” is that a PC connected
to a LAN can be used to monitor the operation condition of air conditioners, perform air conditioner operations,
and make initial settings.
This document explains the procedures for making optional settings for the Centralized Controller AG-150A
using the web browser.
Hereinafter, "Centralized controller AG-150A", unless otherwise specified, will be called "AG-150A".
Note: License of "Web Monitor" or "Basic License Pack" is necessary to use the web browser and update program. Register the
license key on the AG-150A LCD screen.
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. Use this license key to update the program or to use the initial setting browser, or in any other situations
when a temporary license key is necessary.
Note: The use of the function of the outdoor units that measures the electric power will require the "Energy Management License
Pack."
Note: Use a security device such as a VPN router when connecting the AG-150A to the Internet to prevent unauthorized access.
Note: "Air to water booster unit" and "Air to water HEX unit" are referred to as "Hot water supply".

2 Setting the Operating Environment
Given below is an explanation of the PC settings and web browser settings that are required for using a web
browser to monitor air conditioner units and perform operations.
2-1 Setting the PC IP Address
You need to set an IP address on the PC that will enable you to connect to the AG-150A using 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 (for example [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, we recommend 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.

3
(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.

setting.
Note: If connecting to more than one AG-150A, you can specify multiple IP
addresses like [192.168.1.1; 192.168.1.2], however, it is also possible to use
the asterisk (*) and specify [192.168.1*].

3 Performing Operations
Given below is an explanation of how to connect to the AG-150A and how to make various settings for the
AG-150A.
Note: If the AG-150A is restarted due to circumstances like a power interruption, wait until the screen on the AG-150A main unit
displays the normal operation screen (it takes several minutes before the normal operation screen is displayed) before
using a web browser to access the AG-150A. If access is attempted while the AG-150A is still starting up, the most recent
data might not be displayed or communication errors could occur.
Note: Default IP address of AG-150A is "192.168.1.1". (Factory setting)

3-1-2 Encrypting the communication data and opening the Option Settings screen
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]/g-50
/administrator.html
Note: For example, type “https://192.168.1.1/g-50/administrator.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

the certificate needs to be added to the Java certificate list. Click the
[View Certificate] button on the screen in step (4) to display the
certificate, click on the [Copy to File] on the [Details] page, and save the
certificate in any desired location in the DER format. Open [Java] in the Control Panel, click on the [Certificates] button on
the [Security] page to bring up the certificate registration screen. On the screen, select [Secure Site], click on the [Import]
button, change the File of type to [All Files], and select the saved certificate. Now the certificate has been added to the Java
certificate list.
