thoughts on autopilot SWG level

[tenax]

would this be a normal function of the autopilot that i had the setting at power level 1 and 50%..the pool went from 80 yesterday morning to 77 today (done running heater aside from if it freezes) and the autopilot i noticed this morning is one led lower than the 50% and i hadn't touched it.

so my guess is that it was done by the autopilot to temp compensate? also, if that is the case, does it compensate for temp rises up as well as down? and what is the approximate variance of temp that causes the autopilot to do so..(i.e. 3 degrees?)
