    Abstract: A system is provided and includes a first controller, a non-transitory computer- readable medium and a second controller. The first controller is configured to control operation of at least one compressor circuit including one or more compressors. The non-transitory computer-readable medium is configured to store instructions of a stage profiler for execution by the controller. The instructions include: determining a target system capacity profile for the at least one compressor circuit; determining system stage capacities for stages of the at least one compressor circuit; selecting some of the system stage capacities based on the target system capacity profile to provide an available system capacity profile; generating modulation information based on the available system capacity profile and a load request signal; and controlling operation of the one or more compressors based on the modulation information and according to the available system capacity profile.

    Abstract: A system includes a converter and a controller to control a compressor and operates without receiving power supply from a thermostat. The converter receives a demand signal from the thermostat that is used to power the controller and charge a capacitor. When the thermostat de-asserts the demand signal, the charged capacitor powers the controller, which saves system parameters in a nonvolatile memory and enters a power save mode. The life of the nonvolatile memory is extended by alternately storing the system parameters in different memory locations. The system normalizes outdoor ambient temperature (OAT) during a demand cycle. The system determines OAT slope, which is used to select durations to operate the compressor at different capacities, by performing time based calculations during a demand cycle, demand cycle based calculations at the start of a demand cycle, or time and demand cycle based calculations during a demand cycle.

    Abstract translation: 系统包括转换器和控制器，以控制压缩机并在没有从恒温器接收电力供应的情况下运行。 转换器接收来自恒温器的用于给控制器供电并对电容器充电的需求信号。 当恒温器解除请求信号时，充电的电容为控制器供电，控制器将系统参数保存在非易失性存储器中并进入省电模式。 通过交替地将系统参数存储在不同的存储位置来延长非易失性存储器的寿命。 系统在需求周期内使室外环境温度（OAT）正常化。 该系统通过在需求周期期间执行基于时间的计算，在需求周期开始时基于需求周期的计算，或基于时间和需求周期的计算来确定用于选择持续时间以操作不同容量的压缩机的OAT斜率 一个需求周期。
