Domestic thermostat issue
Woke up this morning and turned the furnace up from 65 to 70 to take the chill off. Furnace worked fine, however the thermostat does not read “FURN” as it did last night, but reads “A9UA” instead of “FURN”. Turned the system off then on, no change. Hit the battery disconnect switch then back on, still no change. I looked at the operating instructions and this does not look like an error code. Any ideas or experience with this?
Should read Dometic, not Domestic (spell check)
