ABSTRACT:
An operating system for a dual fuel heating system having first and second heat pump stages, first and second gas furnace stages, an executive controller for tracking time increments and call control strategies at appropriate levels, a demand control for calculating the amount of time each heat pump can be on during a predetermined time window, a data storage apparatus, a thermostat, a first predicting module for predicting non-heat pump electrical load based on a moving average, a second predicting module for predicting heat load based on a moving average, and a limiting module for setting demand limits for off-peak, mid-peak and peak periods. The executive controller is operated to initiate operation of the foregoing routines to determine, based on historical building profile information including non-heat pump electric power information the availability of heat pump power with no increase in demand charges during any given incremental interval. In a further aspect of the invention, break even points are calculated to determine the economic feasibility of increasing the demand set point incrementally in a dual fuel system. The system integrates intelligent demand logic and conventional thermostat logic algorithms into a dual fuel control system.
