Job Checkin

A clothing retailer in Cerritos California reported that their thermostat won't turn on or off. Our A/C technician found the main controller was not communicating for their EMS system. Troubleshooted and spoke with EMS tech support, who recommended pulling a new cat 5 wire to plug into the server and confirm if controller is faulty, as it is older. Ordering new wiring and will return.
