Abstract: A method and apparatus for centrally controlling a hybrid furnace, heater, and boiler system installation which increases the operational cost efficiency of the hybrid installation by computing the operational efficiency and fuel costs of the individual furnace(s), heater(s), and boiler(s) and signaling the most advantageous choice. The apparatus may further embody thermostatic control functions.

Abstract: An electronic control for an automatic filling beverage dispensing valve is shown. The dispensing valve includes a valve body, a flow control mechanism and a solenoid. The valve further includes an electrically conductive cup actuated lever for operating a micro-switch that is operatively connected to the electronic control of the present invention. The valve body includes a nozzle and a stainless steel electrical contact for providing electrical connection between the electronic control and the beverage as it flows through the nozzle into a cup. The electronic control of the present invention is microprocessor controlled and includes an internal signal generator which generates a signal independent of the input line frequency supplying the power to the control. This generated signal is buffered and applied to the dispensing cup lever while simultaneously being applied to a reference input of a phase-locked loop detector circuit.
