So each room can have its own individual control unit to control the temperature of that particular room but does not affect the temperature of the other rooms.
If you ever lived in a home that had several people with certainly odd temperature preferences, you might want to consider getting zone control of the Heating and A/C systems. So what is a zone control Heating and cooling system, well his own controlled heating and cooling system is when you are able to split the heating and AC unit to several rooms to be used individually, rather than have a control unit that certainly only controls the temperature in the home for the entire house, the control unit for his own control heating and AC system will control the hot and cold temperatures for all the rooms. So each room can have its own individual control unit to control the temperature of that particular room but does not affect the temperature of the other rooms. If you go to the home everyone this is a great component to have because you can allow every person to have their temperature preferences just where they want them! Also works if you just like to have odd hot and cold temperatures in your home. So for example, say you want your bedroom to be 68 degrees, but you want your bedroom to be 73 degrees you could do that using his own control Heating and A/C system. These are powerful little devices that are great for those that need them. This is why if you were thinking about getting a zone control heating and AC system that I would highly recommend, what more perfect way is to use 1 of these to acquire access to the ultimate temperature control.
