Abstract:
1. An electric heating and cooling device adapted to supplement a furnace or cooling unit having an air duct extending therefrom for transferring air from the furnace or cooling unit to a room, said heating and cooling device comprising: an electric heater; a fan adapted to propel air through the air duct; a housing defining a fluid passageway for containing said electric heater and said fan, said housing adapted to be coupled to the air duct whereby substantially all of the air passing through said fluid passageway and on to the room is received from only the air duct regardless of whether either of said fan or said electric heater is operating; a thermostat for selecting a desired upper threshold temperature or lower threshold temperature in the room to be heated or cooled and for detecting a temperature in the room; a control in communication with said thermostat and said electric heater and said fan, wherein said control is adapted to independently, activate and deactivate said electric heater and said fan based on input from said thermostat; wherein said control is configured to automatically activate said electric heater and said fan when the temperature detected in the room is lower than the desired lower threshold temperature; wherein said control is configured to automatically activate said fan without activating said electric heater when the temperature detected in the room is higher than the desired upper threshold temperature; a discharge air temperature sensor adapted to deactivate said electric heater when a temperature of air being discharged from the air duct is higher than a selectively chosen limit temperature; a temperature limit control adapted to deactivate said electric heater when a temperature of said electric heater is higher than a selectively chosen limit temperature, wherein said temperature limit control is resettable to allow activation of said electric heater when said electric heater cools to a temperature below said limit temperature; and a vibration insulator sleeve comprising a cylindrical hollow fabric member having opposite ends with an annular ring at each of said opposite ends, wherein one of said annular rings is configured for attachment to said housing of said heating and cooling device and the other of said annular rings is configured for attachment to the air duct.
