aqua stat and superstores

I have a steam boiler with two superstar 80 indirects, each tank has a temperature control set to 140 and I have an anti scaled valve on the hot water side. I currently have an aqua stat on the side of the boiler to keep the boiler water at 160 all the time. Do I need the aqua stat of is this redundant and can I just run the indirects off of the temp controls. I feel like I am waisting gas keeping the boiler at 160 when the indirects are hot and the temp controls will call for heat when the tanks fall below the max setting of 140. Please let me know if I am off track.

    Since I know you are all going to ask for pic shouldn't this call the boiler for heat when it goes below the set point?cid:CCE82869-9D62-4437-AB05-6621A8680788

    So why do I need this to hold the boiler at 160?

    You need the boiler aquastat not to keep the boiler hot but to keep it from making steam during a domestic call. Without it, the boiler is solely operating on pressure.
