The ZonexCommander communicates with one to 80 rooftops, units, splits or zone systems. It provides Internet access with every thermostat or modulating zone in the system. Signage, parking lot lights, exhaust fans or other devices also can be controlled and scheduled remotely or on site. Return and discharge air temperatures can be viewed remotely. The ZonexCommander can be used in new or retrofit light-commercial projects. The system uses two communication wires and two power wires to simplify installation time and costs. ZonexCommander combines modulating zone systems with stand-alone equipment, allowing remote communication with every unit and control in the system.
