When I arrived, I was told heating wasnâ€™t operating. I started diagnostic and found three error codes on thermostat. All communication errors not finding smart hub or zone board. I re wired new bundle from smart hub to zone board. That didnâ€™t solve issue. I grounded out all wires that were extra in bundle and that didnâ€™t resolve issue. Need supervisor to come out to correctly diagnose issue to clear all three error codes.
