...while I understand the general idea,  I find I am always adjusting the temp, and my assumption is the food pedal is only on off, correct?  

 

yes, it's only on/off. you adjust the temp and flowrate from the faucet (and leave the faucet on). i had some small doubts, but after using it, i love it.

 

by default, i leave it warm-hot (but not scalding). it almost doesn't matter which temp anyways since i don't have a hot water recirculation system (is that the next project? lol), and i'm often not using the sink long enough for it to get up to temp.

 

when i'm doing dishes, i set it to scalding once, and when i'm done, i move it back to warm. etc.

 

i definitely touch the faucet way less.

So it looks like you have 2 solenoid valves - one on the hot and one on the cold, correct?  Basically, all you really need are 2 solenoid valves, a foot switch and a latching relay.  Hmm..... Now my contractor will really think I'm nuts!

 

yes, but they aren't solenoids. no electricity.

 

they're hydraulic valves, and the working fluid is tap water that automatically works its way into the control lines when you pump the pedal.

using mechanical advantage in the pedal design, it doesn't take much effort from your foot to put enough pressure in the control lines to close open the valves.

Personally, I am not that concerned with aesthetics... I'm more function over form.  So I really don't care if I have a foot pedal on the floor in front of the sink.

 

Now that I think about it, you don't even really need a latching relay.  I can just get a maintained foot switch (capable of repeatedly passing 6A, so more than enough for 2 15W solenoid valves)... it can be attached to a flexible jacketed cable and float on the floor near the sink.

 

:D things that work well ARE beautiful!

 

but there's also the euro (lever) style one i mention in the OP:
