A clothing retailer in Valencia California reported issues with their kids' department air conditioner. Upon arrival the technician found a commercial Trane system starting up with two compressors when calling for only 1 stage of cooling. Troubleshooted by removing control board and testing with a thermostat, and walking through programming with EMS. Discovered an issue with the y1 calling and the unit registering a "heat" call, bringing on both compressors. Work with EMS who will adjust the settings on the boards to correct the issue. Will return to confirm site is cooling within 2-3 business days after adjustments.
