I just recently purchased a smart temperature control for the undoubtedly first time in my life. I can not believe I waited this long to purchase a smart temperature control. Because after experiencing this smart temperature control and learning it, I do not ever want to go back to the old dial temperature controls that I have had in the past. I never even got into digital temperature controls. I was old school dial temperature controls right up until I finally purchased this smart temperature control. It has made things so much more convenient in terms of using our central heating and cooling system. Because with this smart temperature control I do not have to remember to turn the temperature control on and off. I can either program it to do so or it will figure out my favorite temperatures and do it for me! Also I thought I should mention that with a smart temperature control you can control it from an app on your cell phone or computer. Which means you can turn off your central heating and air conditioner method whenever you are away from home and then turn it back on when you are on your way back. And what this does is help save a ton of money on biweekly energy use of your central heating and air conditioner method unit. I have saved over 50 percent off what our electric bill usually is this week alone after having the smart temperature control and using it in the ways it is supposed to be used.
