For 30+ years the cottage has always been kept at 46(ish) all winter without an issue I ever recall. At the end of the day I guess that's not a huge difference, just sayin... We did finally incorporate a wifi thermostat which is great for adjustments on the road so the place is ready (warm/cool) when we arrive.

My mini split heads won't go below 60 degrees. I'm assuming because they do a good job of maintaining temperature, but they are very slow to heat up a home if set too low.
I turned 2 of my heads down to 60 degrees and the other 3 I turn off one weekend when I went away. The morning I was going home I turned them up to 68 and when I got home that afternoon the house was still cold.
What I've learned, and it's only been a few weeks, is it's best to set it and forget it. If you do change the temperature, you don't want to change it more than a couple degrees. I'm still learning as the temperature outside starts to drop more every day.
So far, I'm very happy with the system but I also kept my oil boiler system as back up. We'll see how long I can go before resorting to turning up the oil heat. We are generally happy if we can keep the indoor temperature at least 65 degrees.
