hi i live in Connecticut i have a complete buderus system g115-28 with lt 160 tank.
i use baseboards as my heating emitters i think my heating curve is not set right i seem to be using more oil with outdoor reset then i did without it.
dose anyone know of the right heating curve for Connecticut
my house is well insulated and have good Anderson windows
my baseboards are sized for 170 on -8 deg day
with the 2109 control my burner ran for 6 min and satisfy the t-stat
now it take a good 12 min burner run time
could someone help me program this to save my oil

heat curve setting
If you system is sized correctly, with proper design criteria and sufficient baseboard, a heat curve of 1.3 should be just about right. Using a base line of 70*, at 8 below zero, that's a 78 temp drop....raising the system temp 1.3 degrees for each degree of outside temp drop would raise system temp 101 degrees to 171, which is right on your design temp. If this doesn't help, you may have a mechanical, design, or a sensor fault. This would be the time to get a pro in there to check things out.

sounds like the same setup i have try uping your day and night temps on the control so lets say your day temp is 68 try bringing it to 74 and bring your night to 72

i will try that tonight and see but i would still like to figure out on the buderus chart how to read the curve so i can set it right
i am looking for the right setting i want my house to be 72 deg during the day and 70 at night.
my baseboards are designed for 170 on a -8 deg day can you give me my ref temp rooster and the right offset
that will make sure my system is set right

Brian, call Buderus tech support at 1-800-Buderus; they will be glad to help you. Your ref temp seems okay; there are a number of other settings that could affect how long the burner fires; Buderus tech support can help you navigate all of the settings as a whole picture.0 -
