The kent one has a solenoid . is that a means to shut off RODI supply ? 
 
eg , the one Reef Pilot posted . if that is the complete assembly . clearly just shuts off the filtered water

 I have the exact same Kent float in my reservoir and mine did not come with a solenoid.  I don't have a solenoid on my input line so you can probably install this Kent without it.  I suspect they've simply started to supply you with the solenoid in case you want to put it on the input as well.
