I have gotten mixed answers on this question so i would like more feedback. We are in Indianapolis. Right now highs are in mid 70s lows in mid-hi 50s. Upon pool opening water temp is 63 degrees. We have a heat pump which is more efficient as ambient air is at 60 degrees or higher. Therefore we are running the heat pump in daytime hours only. My question: On a sunny day with temps between 70-80 degrees, heat pump running, should the auto cover remain closed or open? I can see the logic in both but wanted to know if there are facts to support which is more effective in raising water temp faster. (We obviously keep cover closed at night)
Auto cover open or closed for faster heating?

Heat loss will be less with the cover closed, obviously, especially if there is wind, which will suck the heat out faster than you can imagine.
I experimented with this all-last summer or most of last summer as our pool was put in and became operational mid July. We had a gas heater (LP to be exact) and I'm currently heating it up with the cover closed. It currently 64dg but there is a steady 15mph so I got the cover closed and just checked my heater (currently set to 75dg) and it's not running, and water temp is 77dg. If there is much wind at all the wind creates waves and ripples in the water which cools it. So my findings are much like 1poolman1 described, no wind & sunny cover open.....windy but sunny cover closed to heat up the water. BTW I'm in Shelbyville just South of you-always good to see a fellow Hoosier on here and WELCOME TO TFP
