Or will the thermostat help control that?

Answer:  No, you set the needle valve to flow all the time but the burner only lights when you squeeze the trigger on the wand.  This is the reason for the needle valve.  It is an exact and precise adjustment.  The burner should only kick on and off as you use the cleaning tools and does NOT burn in standby mode.   If the burner lights in standby mode the flow rate is too high and this is super dangerous!  The thermostat is a secondary control device but has nothing to do with flow control, only water temperature.  The idea here is if I trickle a 1/2 a gallon a minute and the cleaning tool uses 1/2 gallon a minute the burner only lights when I squeeze the trigger for my cleaning stroke because the combined use is now over 1 gallon per minute.   Please note the default flow switch is set to one gallon per minute so you combined tool use and water trickle use just need to combine over that number.  As you change pressures and tools and readjustment might be necessary.
