Aqua Hot Furnace Issue
We have a 2003 U320 with the Aqua Hot system. The system seems to run fine - we have plenty of hot water, but the furnace fans will run from 20 to 45 seconds then shut off. Eventually we get to the temp set on the thermostat, but it takes forever and the Aqua Hot burner is running the entire time. We don't have this issue with the heat pumps. We are on our way south for the winter and are in an area where the night temps are too low for the heat pumps. Any ideas?
