Abstract
In accordance with the principals of the present invention, a furnace unit adapted to be installed in-line with a fuel source of a furnace modulates natural gas or propane to reduce fuel consumption, minimize temperature overshoot, and reduce furnace short cycling. A modulator is contained with the furnace unit. The modulator is in gaseous communication with the in-line gas fuel source. A furnace sensor senses furnace criteria related to the operation of the furnace. A microcontroller receives from the furnace sensor furnace criteria and controls the modulator based on the furnace criteria. In a further aspect of the invention, an environmental sensor can be provided to sense environmental criteria related to the operation of the furnace. In a further aspect of the invention, a base unit in electrical communication with the furnace unit can be provided, the base unit determining energy consumption usage and savings. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
