From the description page, this is a versatile control that ccould be rigged a number of ways. It is a slave module that seems to be able to use a number of control modules as an input. It can take a common on/off command or who knows what kind of speed signal. I wish i could read Chinese.
Whatever input signal it takes, it responds by supervising the compressor. It has some thermistor thermometers that I imagine you would fasten to the rig to tell the control board what is reacting how. The chip next to the bridge rectifier looks a lot like the one inside the sanyo that died...high voltage and pwm signal goes in, 3 phase drive signal goes out.
