    • A recovery algorithm for a setback thermostat uses the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the recovery temperature line. The update of the recovery temperature line slope is based on miss time, i.e., the time between actually achieving the desired next set point temperature and the next set point time associated with the next set point temperature. If the heating or cooling load on the space changes, the recovery temperature will frequently cross the recovery temperature line at a different time, causing recovery to start at a time more compatible with the current heating or cooling load in order to complete recovery at or near the desired time.
    • 用于挫折温度调节器的恢复算法使用空间温度与倾斜恢复温度线的交点,其接近温度变化作为时间的函数,从温度受控空间从挫折温度恢复,以确定恢复时间 到占用温度应该开始。 当当前空间温度穿过回收温度线时,恒温器开始恢复。 实现本发明的装置和方法的有用特征是计算和不断更新恢复温度线的斜率。 恢复温度线斜率的更新基于缺省时间,即实际达到所需下一个设定点温度与与下一个设定点温度相关联的下一个设定点时间之间的时间。 如果空间上的加热或制冷负荷变化,恢复温度将在不同时间经常与回收温度线相交,导致恢复在与当前加热或冷却负荷相适应的时间开始,以便在或接近 所需时间。

    • A system for adjusting a bias voltage of a flame sensing system. The system may use pulse width modulation to adjust the bias voltage. The system may have a flame sensing rod that conveys an electrical equivalent circuit of a flame presence to a detector via low pass filter. An excitation voltage may be conveyed via a DC blocking mechanism to the sensing rod. A pulse width modulation signal may be conveyed via a bias resistor to a node of the low pass filter and the detector. The input of an A/D converter may be that of the detector for flame signals. Also, leakages between the node of the A/D converter connection and the voltage source and/or ground may be detected and compensated. Further, leakage of the DC blocking mechanism may be minimized.
