2. Introduction
AE-200A/AE-50A/AE-200E/AE-50E is a centralized controller.
EW-50A/EW-50E is an LCD-less total management system.
Any connected air conditioning systems can be operated or monitored on the AE-200A/AE-50A/AE-200E/AE-50E’s
LCD or the Web browser.
Each AE-200A/AE-50A/EW-50A/AE-200E/AE-50E/EW-50E can control up to a total of 50 indoor units and other
equipment. By connecting AE-200A/AE-200E (main controller) and AE-50A/AE-50E/EW-50A/EW-50E (sub
controllers), up to 200 indoor units and other equipment can be controlled.
Additionally, by integrating AE-200A/AE-50A/EW-50A/AE-200E/AE-50E/EW-50E using the Integrated Centralized
Control Web, up to 2,000 indoor units can be controlled.
Note: When connecting HWHP (QAHV) units or chiller units, the following restrictions must be observed.
• Count each HWHP (QAHV) unit as two air conditioning units, and make sure the number of units that are equivalent to the
number of air conditioning units will not exceed 50 units.
• When connecting chiller units and other units together, count each chiller unit as three air conditioning units, and make
sure the number of units that are equivalent to the number of air conditioning units will not exceed 50 units.
• When connecting chiller units only, up to 24 chiller units can be connected.
This manual explains methods for configuring the necessary initial settings for when using the Air Conditioning
Control System.
Flow of the initial settings and trial run are shown in section 2-2 “Flow of the initial settings and trial run”.
