Dh prefers to keep it set to 55 all the time to keep the gas bill down. He says if you're cold, put on another sweater and grab a cat and a blanket to stay warm!
I turn the heat up when he's gone to warm the house up for the day, then turn it off before he gets home.
Just one of those things that make me go hmm..68 during the day, 62 at night. It stays at 62 during the day when people aren't home too
