The ZonexCommander communicates with up to 80 rooftop units, splits, or zone systems. It provides Internet access with every thermostat or modulating zone in the system, the company says. Return and discharge air temperatures can be viewed remotely. The management system can be used in new or retrofit light commercial projects. Two communication wires and two power wires help simplify the installation, says the company. The unit combines modulating zone systems with standalone equipment, allowing remote communication with every unit and control in the system, states the manufacturer. Exhaust fans, signage, parking lot lights, and other devices can be controlled and scheduled remotely or onsite, the company says.
