Abstract: An electronic controller device for automatic control of a heating, ventilating, air conditioning or refrigeration (HVAC&R) system has a digital recycle counter that is capable of intercepting a thermostat command for cooling, refrigeration, or heating and replacing the thermostat command with a modulated binary signal that operates in an “on” state or “off” state, and a computer-readable storage medium that comprises a program that includes an auto-configuration mode that is capable of determining a base line performance of the HVAC&R system through a commissioning phase and is capable of determining an adjusted performance based on energy consumption, temperature regulation, humidity regulation, or power limit or any combination thereof. The program can adjust the digital recycle counter “on” and “off” states based on the adjusted performance determination to reduce energy consumption.

Abstract: A demand control apparatus includes a switch in the control signal line of an electrically powered piece of equipment. The switch is controlled by a digital recycle counter so as to periodically cycle off and on during times when an equipment generated control signal is present in the control signal line. The control signal line could be a thermostat control line on a standard air conditioning unit and the equipment generated control signal would normally correspond to the thermostat calling for cooling. When the switch is opened the equipment reacts as though the thermostat has been satisfied. When the equipment generated AC control signal is sensed in the control signal line, a digital counter is activated to hold the switch open until a preset number of AC pulses have occurred. The switch is then closed until a second preset number of AC pulses have occurred. The open-closed cycle is repeated as long as the equipment control signal is present.

Abstract: A load demand and operation control and management process for controlling diverse operation and individual electrical requirement of any load or loads of energy-consuming equipment, the process utilizing process apparatus which optimizes the performance of the equipment while precisely controlling and synchronizing the demand of its individual load requirements with the energy supplied thereto, so that the life and efficiency of the equipment is enhanced while load demand is controlled. The process apparatus of the invention consists of a digital recycle counter and a switch placed wholly within the control power line of a load.
