When you have a smart control component there are many ways you can set it.
The first plus foremost way that is beneficial is to program the programmable smart control unit, but you can program it to go on plus off at odd times of the day plus night at a certain temperature.
This is the most energy efficient way to set your smart control unit. The other way to set your smart control component is by hand. This would be a method that is no odd than how you would operate a official digital control component or vintage dial control unit, but simple, easy however not as energy efficient. The other way would be to do it by hand in a sense, however by being able to control it from the app on your cell cellphone. You can turn off or turn on the smart control component from somewhere in the world, but not that you would care or want to mess with your control component if you were out of the country, even though I am just saying that it is possible if you ever so wanted to. It can be an energy saver doing it when you are away from loft plus wanted to keep your central heating plus air conditioner off while you were away or at labor plus then turn it back on when you were coming loft on your way back. This saves energy plus currency as well as using the programmable control component portion of the smart control unit. Smart control units are wonderful in so many ways. If you do not have one yet, by all means buy one soon!
