So far I'm keeping my tub at 103...and for a week or so at 104. Started out at 101 when I got it in October, but that temp was too cool for me when the outdoor temp is sub zero.
I tried the 104 override this afternoon, and set to 105. Checked the temp after a few hours, and even though I set 105 as the temp, the tub display read 106. Checked again an hour later and still read 106 even though 105 is the set temp.
My steps are frozen in place in front of the access panel, so I can't check what jumpers are set in the control box. The display doesn't read ue-1, ue-2 etc, like the link I posted above says it should when overriding the 104 temp. Maybe things have changed since then.
