You could use a bcs-460 or bcs-462. Super easy to setup, but I have to agree that I am not sure it is really worth the trouble. I use a bcs-462 to give me temperature readouts on my still and fermenter and open and close valves for fermenter temperature control. You could also use it to control your condenser water flow. I would think with solenoid valves. In truth though, a simple ball valve there should do the trick as well. You could build in a "big red button", but in general, this whole setup is going to require you to build out a box, though you can have front panel express make you a nice front to your box.
