This controller can monitor and control up to 128 air conditioners. In offices, shops, schools, and other small- to medium-sized buildings, centralized control is becoming increasingly important to save energy. However, Toshiba's field research shows that at some facilities, air conditioners are not managed by trained experts but rather people with no real training in the field. The company realized there was a dire need to review and revamp complicated monitoring and control systems. Toshiba's newly developed controller displays the operating conditions of the entire system while allowing intuitive control of individual air conditioners through slide switch icons and meters.
