I just had my buderus G115WS/4 with logomatic 2107 last week. I took a peek at the "Hours Run" display on the logomatic and it currently read the number "4". I find it hard to believe that the burner ran for a total of 4 hours in a week, since I am not heating the house and it is in WWSD mode. I also hear the burner turn on from time to time, probably once every 4-5 hours with a run time of a couple of minutes at a time.
Any ideas of this?
