Upon arrival found master bedroom unit display saying that it can’t communicate with indoor. Seeing that the Tstat and indoor unit is the only thing communicating checked wiring between hub and display and found it ran next to high voltage and all non-used wires not grounded out to a common. While beginning repairs homeowner stated that she needed to leave. Spoke with office and found they will reschedule the call to complete Upon arrival moved low voltage away from high voltage and daisy chained all unused wires to the common on the furnace. Reset unit and system is still having communication errors from the hub. Hub will need to be warranties out. Ordered hub through Lennox in Allen. Service fee waive due to being a callback. Due to not having any s30 hub, emailed Lennox info to maybe pull a hub out of a new s30.
