Arrived for Infinity system communication error. Spoke with homeowners about the issue. When we run the gas heater we get error 179&178 at the thermostat. Everything is working just fine though. Inspected equipment. Cleaned module chips and reset thermostat. Trimmed back wires at AC, removed wire nuts from com wire, and reconnected. Ran stat through install setup. Cycled system in all stages. No errors present. Spoke with homeowner further to confirm no other issues. System is running properly at this time. Waived fee as we were just out for a tune up.
