When I was younger, my siblings and I use to always fight over everything.  Whether it was toys, what movies to watch, or what food we were going to eat for dinner.  You name it, we fought about it.  It was kind of a ritual in a way and looking back now I think we all kind of enjoyed the drama I think.  However, there was one thing that we could never agree on that drove our parents crazy, and that was the temperature setting on the thermostat!  It was so aggravating!  We all had different temperature preferences for our bedrooms when we slept, and one setting definitely did not fit for we.  I liked things colder, and my other siblings liked things much warmer. So, either I was happy, or nobody else was happy.  So, after my parents were tired of hearing we argue, they went to their local HVAC store to see what their options were.  They discovered that there were tons of new technologies out there for us to use to solve our very specific heating and cooling problem! They came home and told us the good news, that we were getting a thermostat with zone control!  This meant that we could each have different heat and air conditioning settings in each of our rooms throughout the house!  It was the perfect solution! The very next week, the HVAC technician had arrived to install everything and we could not have been more excited! That first night, I had the best sleep of my life all because of that zone control.
