Abstract: An electronic controller device for automatic control of a heating, ventilating, air conditioning or refrigeration (HVACR) system, which has at least a delayed start controller that is capable of delaying sending of a signal to power on a load unit and achieve a selected conditioned space temperature variation, and a demand regulator controller that is capable of calculating on times and off times to obtain a selected electrical demand. The electronic controller device can include a computer-readable storage medium that comprises programs to implement the delayed start and demand regulator controllers, and optionally other controller modules, can delay OEM ON signals and/or adjust the “on” and “off” states, and/or provide other load unit control, to manage and reduce energy consumption and/or demand.

Abstract: Method to automatically manage and provide energy control and estimated energy savings for duty cycled HVAC&R equipment in an improved manner as compared to operation with hysteresis on/off thermostat control itself, wherein a time delay for control signals is determined which can provide selected energy savings and can be applied to control signals to a load unit. An electronic controller can be used as an add-on device in HVAC&R systems with thermostat control which automatically manages and provides the energy control for estimated savings for duty cycled HVAC&R equipment.

Abstract: Electronic controller apparatus for automatically controlling and managing load demand and operation of energy-consuming equipment powered by alternating electrical power current, whereby feedback signals from a vapor compression evaporator or other source, and possibly other physical signals, are used to supplement the pre-fixed, learned, or default settings to optimize compressor operation (run time) in cooling and refrigeration equipment, and thereby to improve heat transfer in the evaporator. The effect is to improve the Energy Efficiency Ratio (EER), Seasonal Energy Efficiency Ratio (SEER), and Coefficient of Performance (COP) for the unit, and provide other advantages and improvements. In gas-, oil-, and propane-fired HVAC&R heating systems, the apparatus can also optimize burner operation and thereby improve heat transfer across the burner heat exchanger. HVAC&R systems that incorporate the demand controller and methods of their operation also are provided.
