Our AO Smith hot water heater has a Honeywell thermostat.

Customer Question

Our AO Smith hot water heater has a Honeywell thermostat. While installing ductwork in the basement our HVAC worker noticed that the red indicator warning lights were flashing three times in a row, pausing and then repeating the three flashes.
Would you be able to give us feedback on this? Thank you, Pat
