Abstract:
A method for adjusting the temperature set point of a HVAC unit and activating and deactivating said HVAC, comprising the steps of:A. recording thermostat activations for a controlled environment at set intervals over a defined time period; B. creating an ideal HVAC demand model for said controlled environment; C. at the conclusion of said defined time period, 1. creating an actual HVAC demand model for said controlled environment, based on said recorded thermostat activations; 2. comparing said actual HVAC demand model to said ideal HVAC demand model and determining a temperature change factor; 3. calculating an optimum temperature set point for said HVAC unit, based on said temperature change factor; and 4. adjusting an actual temperature set point for said HVAC to said optimum temperature set point; D. continuously monitoring temperature of a transfer medium of said HVAC unit; E. comparing said temperature of said transfer medium to said temperature set point; F. activating said HVAC unit when said temperature of said transfer medium deviates from said temperature set point by more than a temperature set point range differential; and G. deactivating said HVAC unit when said temperature of said transfer medium returns to a temperature equivalent to said temperature set point.
