Warranty work. I found that the system had the Y1 disconnect and not running in a/c mode. I hooked cooling side back up and took temp split from the unit and inside from the vents. They both are within range for proper function. Found that one stat was not clipped in all the way and had dead batteries. I replaced the battery’s in both stats and reclipped one back into the docking station. At this time everything is working on the call back.
