Does Buderus make any controller that does not use outdoor reset?

rog2e Member Posts: 16
After looking everywhere for a used R2109 and not finding anything I am just wondering if Buderus makes a simple controller that does not use Outdoor Reset. Most of my heat comes from an outdoor wood boiler with only the Buderus as a backup. (The wood boiler is piped in directly to the Buderus and the Buderus will only kick on its burner if the temp falls below the low limit). So I am really only using my oil maybe 20-30 percent of the time and that's only if I go on vacation or I just forget to load more wood. A sophisticated R2107 or any outdoor reset wood be a waste for me. I know that there are other models but the real for me is that I don't want to have to swap out the Buderus immersion well. So I guess if there is another brand that will still let me use the Buderus immersion well then I might look into that as well.

    You're prepared to rewire from a 2109 to conventional control but deterred by swapping the well?

    I am sure you can get a Honeywell aquastat to fit in/on the well sensor. Many have a sensor that can be extended.

    honey well 7224u is a good control you can run low limit down to 120, might have to change the well

    What's your aversion to changing the well?

    If you don't have a LWCO, then a Hydrostat 3250 will give you cold start, triple acting and low water protection. Just use the Hydrostat well. What the dilly yo? Takes about 10 minutes to change the well.
