wherein the control system is configured to shut down the heating and cooling system of the room when the control system detects that the room is currently unoccupied, and to monitor the temperature of the room until the temperature reaches or exceeds a maximum or minimum threshold temperature; and
wherein the control system is further configured to operate the heating and cooling system of the room for a first predetermined period of time when the temperature of the room reaches or exceeds the maximum or minimum threshold temperature.
