I don’t have a separate zone for heating in the STR (do have window AC units). What I write in my rules and in my checkin info, the temperature that I heat the house but I am willing to increase (within reason) and I do. I just tell them to send me a message. I have a wifi thermostat so it’s easy to change.
I once had a guest ask me to raise the heat to 80 degrees. I knocked on the door to explain that 80 degrees is too high. He was wearing shorts and a tank top. Unbelievable.
In the Summer I remind guests to shut off the AC when not in the suite and luckily they seem to do this but not always. I do have it in my rules that I can enter to turn of the AC but I have never done that and probably never will.
