He only used one inlet on furnace and did not install a bypass loop. If furnace is installed correctly with use of both inlet and and a bypass, then pumps should run longer and get heat to last radiators quicker. Hope this helps.
I have a bypass loop but I am still not sure what you mean by( he only used one inlet?)
I was told that there is a lever in the thermostat that I can adjust. But I am not sure which way to go with it. Any suggestions?
