I am very basic when it comes to technology; I entirely don’t like to replace things or get with the times. I still have my first flip iphone. It gets the task done, never needs replacement, as well as it refuses to break. I still own an MP3 player rather than an iPod. The little player keeps a charge for many hours and never has an issue. I also have kept the same HVAC unit in our lake house since I have moved in. I have a basic forced air HVAC unit. It provides both heating and cooling. I control which one as well as how much through a dial thermostat. The thermostat is a basic turning wheel that I move to get the temperature I want. I have it set at 60 in the Summer. If the weather gets hotter and the inside gets warm, the cooling system naturally turns on. In the Winter season I go for 65. If the chilly temperatures drop, the furnace automatically turns on. I don’t have to mess with telling the system when to do heating or cooling; it just does it. I set our thermostat two times a year, then I leave it alone. I have heard about smart thermostats. They just sound like a pain to operate though. The smart thermostat requires a weekly program. It also wants times, zones, as well as mornings set for the temperature control program. I refuse to put in that much work… Also, it runs on Wi-Fi. If you lose internet or power, no climate control for you. My dial thermostat never stops doing its task as well as requiring nothing from me.
