My new boiler has the 3250 plus, couldnt get boiler to go over 140, so i shut off the econo and removed the jumper next to the zone/indirect switch, now goes up higher, but still having trouble with getting house above 68deg, or boiler above 170. Can someone explain the purpose of the jumper and what a good hi/low setting is? Currently at 180/160. Ive got an indirect with zone pumps. What good is the econo if you have to shut it off to get the temps up?
