Setting Aquastat at 240 to hit 190?

I just installed a new L4006A aquastat because my boiler temp never exceeded 180, which on cold 0* days, means my house peaks at 68*. So I figured the 30-year old aquastat needed replacement. Wrong!
Tonight I got the new aquastat, filled the well with conductive grease and installed the new one. Setting it at 240* with 10* differential, the boiler maxes at 190*.
How accurate are the aquastat temp settings? The thermometer/pressure gauge is also new. Th boiler is a WM GV-5. It just feels wrong setting the temp so high.
