Abstract

An automatic temperature control system for a building that includes a night setback feature and a morning pickup feature that operates as a function of outside air temperature and wind velocity. A seven day time scheduler and a short cycle auxiliary timer control the system operation. System automatically resumes proper scheduled operation following power failure that does not exceed mechanical carry-over time of seven day time scheduler.
