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.
By using a PI controller that is built-in on the AE-200A/AE-50A/EW-50A/AE-200E/AE-50E/EW-50E, the energy-
control-related status can be displayed and Peak Cut control can be performed without a use of a PI controller
(PAC-YG60MCA).
Each AE-200A/AE-50A/AE-200E/AE-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.
