\"There is a Shower Valve Feature option on the product page for you to choose standard valve and thermostatic valve.For the standard shower valve, one knob is to control the hot water and another is to control the cold water, the middle knob is the diverter, it can turn 360 degrees. Through the diverter, two functions can work simultaneously or only one function works at a time. By adjusting the hot water knob and the cold water knob, you are able to control the volume of water and also the temp.For the thermostatic shower valve, one knob is to control the flow to either Function A or Function B, one knob is to control the Function C and the middle knob is the thermostatic control of temp.
