Most home thermostats are hard wired into the furnace. They have a low voltage control wire that runs from the thermostat to the furnace, which is how the thermostat communicates with the furnace. Wireless thermostats allow more flexibility with the placement of the thermostat. If you want to relocate the thermostat at a later date, you don't have to run a new wire in the wall if you have a wireless thermostat. You can keep the thermostat near you to further increase your comfort. It is fairly easy to install a wireless thermostat, and is actually less complicated than a hard-wired one.
