1 Introduction
Special features of Mitsubishi Electric Corporation’s “Centralized Controller AG-150A,” “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, perform air conditioner operations, and make initial settings.
This document explains the procedures for making initial settings for the Centralized Controller using the web
browser. Hereinafter, the centralized controller AG-150A, 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".
Note: As GB-50ADA-A and GB-50ADA-J are not equipped with a LCD for settings, the initial setting must be made on the Initial
Setting Web.
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.
