I installed the outdoor thermostat and set it so the high fire burner comes on at 20 degrees. So most of the time, the boiler is putting out 150K btu (it's 300K btu with both burners running). We have 3 hydroair zones that come off an Ergomax buffer tank. I currently have the operating temp of the boiler at 180 and the high fire burner set for 150 degrees inlet temp (when the outdoor temp is less that 20 degrees). The Ergomax tank thermostat is set to turn on the boiler at 160. We also have a Heat Manager. What do you think of these settings? Should we tweak any of these? Thanks again.
