For those of you in colder climates, what do you leave your heater temp at while away for a week or so? This is our first time leaving the house during cold weather so I am not sure what is best thing to do. Thinking of programming it for 55 at night and maybe 61 during the day? We have two indoor cats but if it is cold, they will just cuddle up and sleep anyway. I just don't want it to be running a lot. We normally keep it at 55 at night and 63 during the day.
