Product features

The AT-50B described in this manual is a centralized controller with color LCD touch panel for air
conditioning units, LOSSNAY, Air To Water (PWFY)*, and general equipment using the Mitsubishi Electric
DIDO controller (PAC-YG66DCA).
AT-50B can control up to 50 units/50 groups.
AT-50B controls and monitors the air conditioning units of each group. AT-50B also can control detailed
scheduling and prohibits the local remote controller operation in each room (group), which may lead to
energy savings.
Basic operations are accessed through the AT-50B touch panel. ON/OFF, F1, and F2 operations that
control air conditioning units collectively are accessed by using buttons next to the touch panel.
