Three controls from Mitsubishi Electric aim to help commercial building operators monitor the company’s City Multi Variable Refrigerant Flow zoning systems from a single online portal. The SmartME Zone Controller (shown) can operate up to 16 indoor units in a single zone; the AdvancedHVAC Controller’s custom applications integrate indoor units with third-party equipment such as auxiliary heat and energy recovery ventilation systems; and the EB-50 GU-A Central Controller offers Web-based control of up to 50 indoor units within the same building. The components can be used together or individually.
