1. A system for using outside ventilation air to maintain indoor comfort and air quality, comprising:

  • a sensor system for detecting outdoor and indoor air temperatures;

    an air delivery system for delivering the outside ventilation air to an interior space; and

    a programmable controller, operably connected to the sensor system and the air delivery system, that includes;

    a recovery element that receives an outdoor air temperature and an indoor air temperature detected by the sensor system;

    a storage element that stores the detected outdoor air temperature and the detected indoor air temperature detected by the sensor system;

    a calculating element that automatically calculates a predicted indoor temperature range and a predicted outdoor temperature range based on the stored outdoor air temperature and the stored indoor air temperature; and

    a regulating element that automatically regulates operation of the air delivery system as a function of predicted indoor and outdoor air temperature ranges and a predetermined indoor air temperature range.
