I am working on an RTAA 340 and want to initiate outdoor reset but I am confused on the reset ratio.
I have a 29*F LWT setpoint.
I want to start reseting at 60*F OAT.
I want to set max temp at 40*F LWT.

Correct me if im wrong...
Maximum reset = 11*F LWT
Start reset = 60*F OAT
Reset ratio = 10%

What would my low OA temp be at 40*F LWT??? 10% lower of the 60*F??? 54*F???

Thanks
Clayton
