There are many types and styles of thermostats. Your thermostat
may look different from the one shown, depending on the type of
thermostat and whether cooling was installed with the system.
However, almost all thermostats perform the same basic
functions.
There are 2 switches located on the thermostat. One switch
controls the heating and cooling (if applicable) functions. The
other switch is for FAN operation, either continuous or automatic.
Also on the thermostat is the temperature range for the desired
heating and cooling temperatures.
