No. They’re programmable thermostats so you set them to what levels you want during the time periods you want. It’s not like I’m going to freeze at this time of year if I go away, so it doesn’t matter if it’s set to cool. I usually set my temp to around 70 for both heating and cooling. It just feels the best. Some days if it’s one of those real cold windy days I’ll override a bit warmer and conversely if it’s one of those hot/humid days in the 90s I’ll drop the temp a few degrees to help the system a bit.
