1 Introduction
A special feature of Mitsubishi Electric Corporation’s “Central Controller G-50A” and "Central Controller
GB-50A" 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 Central Controller G-50A using the
web browser.
Hereinafter, the central controller G-50A and GB-50A, unless otherwise specified, will be called "G-50A".

air conditioner. Enter the value that is 10 to 15% below the maximum
demand value (average electric energy value in 30 minutes) in the
blank next to Level 4. Decrease the value by about 10 % for each
level below. (The figure on the right shows the system with the
maximum electric energy at 200 kW.)
Note: The best set point depends on the system configuration of the electric equipment and the indoor environment in each
building. Choose appropriate set points accordingly.
Note: The amount of electricity that is actually used may exceed the demand value due to such unexpected incidents as controller
problems or broken transmission lines. Mitsubishi will not be responsible for such incidents.
5-2-5 Setting the temperature difference between set point and inlet (All methods)
When the energy-save level is set to 0 (It is always set to
level 0 in an energy-save control method), energy-save
control will not be performed for the indoor units that
show a greater difference between the set temperature and indoor temperature than the value set in the
window on the right.
Make the setting when some type of energy-saving control is effective at energy-save level 0 and the level of
comfort is high on priority list. (Choose between 3 to 9)
21
5-2-6 Setting the Outdoor Unit Control Method (All methods)
Make the energy-save control setting for the outdoor units for each energy-save level.
Note: M-NET addresses are displayed on outdoor units of City multi type. M-NET addresses and group names are displayed on
