What is an example of how this thermostat system us used???

If Your current thermostat is located next to a heating vent, the heating system may shut off prematurely before your bedroom reaches the desired temperature. Solution: Place the T8665A thermostat in your room (the wireless module (W8665A) is installed in-place of the old thermostat) and the heating system will be regulated by location of the T8665A thermostat in your room, instead of the location of the previous thermostat.
