Patent ID: 7261241

Claim:
A system for maintaining user-selected temperatures in multiple areas within a facility having a heating and cooling plant having conduits that circulate fluid for transferring or removing heat from the multiple areas within the facility, the system comprising: area thermostats, each area thermostat sensing a temperature of a particular area within the facility and comparing the sensed temperature of said particular area to a user-selected temperature for said particular area; and energy savings devices, each energy savings device being associated with a respective area thermostat, each energy saving device comprising: a housing adapted to be secured to the conduits; a first thermostat receiving a first pre-selected temperature setting from said respective area thermostat, said first pre-selected temperature being determined in accordance with said user-selected temperature, said first thermostat sensing the temperature of the fluid within one of the conduits and comparing the sensed temperature of the fluid to said first pre-selected temperature, the fluid attaining said first pre-selected temperature based on the operation of said facility heating and cooling plant; and a fan contained within said housing, said fan being in electrical communication with said first thermostat and with said respective area thermostat and operational to transfer heat to, or remove heat from, said particular area of the facility to substantially maintain said area near said user-selected temperature for said particular area, wherein said fan is energized when the fluid attains said first pre-selected temperature and is de-energized when said area of the facility attains said user-selected temperature for said particular area.
