Apparatus and method for control of a thermostat |
摘要 |
A thermostat is provided that includes a temperature sensor for sensing ambient temperature, and a switching device that is configured to apply electrical power to a heating element when the switching device is activated. The thermostat further includes a processor that is configured to periodically determine for a finite switching time period a temperature delta value indicative of the difference between the sensed temperature and a desired set point temperature. The processor is further configured to calculate a duty cycle ratio of the switch activation time relative to the total switching time period. The calculated duty cycle ratio for determining the switch activation time is determined as a function of the temperature delta value, a duty cycle offset and a heat dissipation offset. The duty cycle offset and the heat dissipation offset are based on an average of a predetermined number of prior duty cycle ratios. |
