INSTALLING A NEW THERMOSTAT

Before changing your own thermostat you need to shut the main power off to your heating equipment. You can do this in several ways. If there is a switch near your heating equipment, turn it off. Power can also be disabled at the main circuit breaker panel.

Carefully, remove the thermostat from the wall. Some thermostats have tiny screws holding the main thermostat to the " Sub Base ". Don't lose these screws, they may be needed if you, need to refer to them when wiring your thermostat or for some reason need to re mount this existing thermostat. We have many people who have installed their own  Hunter or Lux thermostat and wish to upgrade to a better thermostat, we will try to give some good instructions on how to be successful! 

Label all the wires as you remove them as to the color and the terminal you took them from. If for instance, someone has run all the same color wires, you'll have to use some ingenuity, labeling them as "white 1", " white 2 " or some other means of identification.  As an example: The Red wire normally goes to the "R" terminal, Yellow and sometimes Blue usually goes to the "Y" terminal. Green wire usually goes to the "G" terminal. Also Heat Pumps have an "O" or "B" terminal which usually uses an orange wire. Worth mentioning here is some manufacturers such as Trane uses a terminal designated as "B" for common. Most manufacturers however, call the common terminal "C". The point is, make SURE you know how to put the wires back on the new thermostat or damage will most likely occur. Consult the wiring and installations that come with your new thermostat. If unsure consult an H.V.A.C. professional.

Just be aware that every installation will be different as to wire colors, the number of wires and so on.
