Living in Central Florida, l pretty much keep mine at about 65 F all year around. Kinda hard to tell exactly where its at though, since my thermostat is one of those old doohickies with the little plastic nub that pans across the top, rather than one of those newfangled digital contraptions which l would prefer.
Of course, even set at 77, our AC has a hard time keeping the house cool enough in this extreme heat, so that the temperature inside is usually reading 80-85.
