Pb 105 installed...up and running Changed all my set back thermostats (up from 50 degrees) and now my wife is very happy(house @ 70+ degrees) My oil still come on at times but in 24 hours it has only run 30 min (hour meter). would like to nip that in the butt. My boiler is plumbed in series and no one here seems to know how to stop my oil burner from comming on . I only want my oil to come on in an emergency. Can anyone help?
