ABSTRACT:
An improved method and apparatus or control system for electronically sequencing the main components in central air-conditioning and heat pump systems normally comprising an outside fan motor, a compressor motor, and an inside blower motor, is disclosed. When comfort production or conditioned air is needed, the outside fan motor is initially turned on. After a predetermined programmable period of time, the compressor is turned on, and then, after another predetermined programmable period of time, the inside blower is turned on to deliver production air to the space or area being serviced. At the end of the comfort cycle, the outside and compressor motors are turned off while the inside blower motor continues to run for a third predetermined programmable period of time. The system and its method of operation provides the most energy efficient operation of central HVAC systems to date while simultaneously increasing protection to the various components of the system, increasing the amount of conditioned air produced per cycle, extending equipment life, and increasing comfort while simultaneously reducing energy consumption, duct loss and wasted energy use.
