The AT-50B centralized controller echoes the "familly feeling" of the control systems by Mitsubishi Electric (AE-200, PAR-33MAA) with a modern and elegant design thanks to the glossy glass-effect front panel, making it an ideal controller for residential applications as well.

AT-50B has, in fact, a 5" backlit touchscreen display through which up to 50 Indoor Units or Groups can be monitored, configured and managed in a Grid, List or Group view.

Two function keys that can be freely programmed between functions specifically designed to save energy and ensure proper conduct of the VRF CITY MULTI system, allow direct access to the selected function.
