Periodically, it is difficult during the spring plus the fall to know which control component setting you should use, then the temperatures fluctuate so much, and I have a difficult time remembering to genuinely check the control unit.
During the spring and the fall, you will find a swing in temperatures.
During the day, the temperature is likely pretty warm, this might change depending on cold fronts and stuff rolling in. During the evening, the temperatures are always cold. This might mean that you have to turn on the furnace during the evening plus the central cooling system during the day. However, depending on the day, you might also have to use the furnace during the day. Some days might be perfect, meaning that you can turn your control component off completely. These temperatures shift day by day, and it can be entirely difficult to remember to turn your control component off or switch settings each time. Most often when I forgot to adjust the control unit, I wake up in the middle of the evening chilly or realize that I am covered in sweat during the day, and I know that there are control units that will do this whole process for you easily, but they are luxurious, and in my opinion, those control units aren’t worth it. I think that it might be easier to set a reminder on my phone to remind myself to adjust the control component at least once at evening plus once in the day after I have checked the weather. Trying to figure out which control component setting you should use is a lot of work.
