I know what you mean. I set the t-stat for 69 yesterday when I came in at 6. I brought my lunch, and one of my guys went to dinner around 7 and picked something up for me. So I didn't leave the office till about 9. Didn't seem at ALL hot when I came out
no idea why so many were bitching yesterday 
That reminds me...just got a chill....may need to knock this unit to 70 today
