    • Methods of controlling air conditioning and HVAC units using a thermostat for a discrete-speed unit that include changing speed based on how long the unit operates at a particular speed. Speed may be increased if a unit operates for longer than a predetermined time at a particular speed, and speed may be reduced if the unit operated for less than a specific amount of time during the prior run. In different embodiments, single-stage thermostats may control units that operate at three speeds, and two-stage thermostats may control units that operate at three to five or more speeds. In addition, in some embodiments, outdoor coil temperature may be measured and considered in determining speed. Further, in some embodiments, maintaining continuous or repeated operation at a boost speed may be avoided. Energy savings and noise reduction may result.
    • 使用用于离散速度单元的恒温器控制空调和HVAC单元的方法,其包括基于单元以特定速度运行多长时间来改变速度。 如果单元以特定速度操作长于预定时间,则可以增加速度,并且如果在前一次运行期间该单元操作小于特定量的时间,则速度可能会降低。 在不同的实施例中,单级恒温器可以控制以三个速度运行的单元,两级恒温器可以控制以三到五个或更多个速度运行的单元。 此外,在一些实施例中,可以在确定速度时测量和考虑室外线圈温度。 此外,在一些实施例中,可以避免以升高速度维持连续或重复的操作。 可能会导致节能降噪。
