Abstract
An optimum start system for determining the optimum start time of a temperature control system within a building so that energy can be conserved by operating the temperature control system at reduced energy levels during periods of non-occupancy of the building and by starting the temperature control system an amount of lead time prior to the beginning of occupancy of said building wherein the amount of lead time is selected to bring space temperature within the building within a comfort range by the start of occupancy, the optimum start system including a space temperature sensor for sensing space temperature within the building, an outdoor air temperature sensor for sensing outdoor air temperature external to the building, and a controller connected to the space temperature sensor, the outdoor air temperature sensor and the temperature control system for determining the lead time as a function of an accuracy factor based upon the accuracy of a prior lead time and as a function of both outdoor air temperature and space temperature.
