Two or three months ago, our partner and I visited a neighbor out of state; They are one of our closest friends, so all of us stayed in their guest room; While all of us were there, they introduced us to the technology of smart control units. At my residence, all of us had just the basic control component that you adjust from inside the home with no special features. The people I was with and I were shocked by all the features that this smart control component had. The number one feature that all of us liked is that you can control the control component from your phone. When all of us were out of the home doing activities, they had set the control component to a higher temperature. Because we were doing this, they seemed to be conserving energy. About forty five minutes before all of us would head back home, they would simply adjust their control component from their cell phone. When all of us arrived back, the air conditioner was at the ideal temperature; Not only was it programmable in this way, however you could also set the control component on a program for your week, however my neighbor explained that the control component is set based off of when they will be home, in an attempt to maintain a comfortable temperature in the hours stuck at home. We really appreciated a charming week of perfect temperature control with our friend. When all of us arrived home, our regular control component just did not seem the same. The people I was with and I made the choice to substitute our control component as well after this visit; It has been a couple of months now, and I must say that the smart control component was a charming technological addition to the home.
