7/28/25 Checked boiler and circulation system for on floor heating. There are wire that are disconnected and covers that are gone off pumps. Customer is checking with the builder to see who installed in floor heat. I checked error code history and found cod F76 which means the boiler and circulating system is not communicating with each other. There are some loose wires on circ board. Me and Mark W. Need to come back first call and trace wires
