In these terribly warm months, if you want to take your cooling (and heating) game up a notch, as well as save some money while you’re at it, swapping out your old, exhausted control unit for a new, modern smart control unit is the way to go. If your old control unit is not too old, the wiring should be quite easy to connect to the new, smart control unit. Smart because the up-to-date control units can be not only programmed to come on or go off at particular pre-programmed times, however with the up-to-date smart control unit technology, you can virtually “talk” to your control unit while you are away from the house, via a smartphone app. Also with smart control units, you can create a custom schedule, view usage history (especially if you suspect that one of your youngsters are playing with the control unit while you are away), as well as these up-to-date smart control units just plain look pretty cool as well as are easy to install as well as to use. One of the most interesting features of these up-to-date smart control units is the ability for that control unit to learn the users habits. The smart technology allows the control unit to remember your adjustments, as well as will, over time, commit those control unit adjustments to its memory, so you won’t even have to worry about manually making any control unit changes throughout the day, then or, you could just take some time when you install the control unit as well as set up an auto-adjusting schedule, however if you are patient enough to wait a couple of weeks, the control unit will do it for you. Now that’s what I call, smart.
