I have multiplexers, but can't tell you how to hook it up since I paid someone else to do it.
On a side note, it could save your air compressor from running all night as well, and possibly burning up.
My thoughts exactly!!
Edie,
Just to add to I.B.'s (Pat's) thoughtful points ... even though your weather is not as cold in Ohio as here in North Dakota ... you may want to do like we do & blow out some of filled with liquid lines depending on how low your current outdoor temperatures are. Even though it is probably low risk ... I am thinking that if a chemical solenoid developed a slight leak ... it could cause a freeze up in a line you had thorougly blown out to prevent such a problem.
2Biz's alternative to a multiplexer could actually take up less space with the thinnest Phoenix relays on a small piece of 35mm din rail. These items can be looked up online & purchased at
www.mouser.com. We like the screw-less version of the relays & crimp ferrules on or use solid wire ... making them more vibration proof & whatever wire connect & disconnect instant & easier. Also both the relays & their bases slip in & out with minimum effort. Visualize a pit stop crew at a the professional car races ... when something goes down ... in our case it could be during a peak business window of opportunity timeframe. Seriously ... between getting more of your customers to use $5 bills & dollar
coins & top notch service friendly equipment ... you could consistently get great thorough put when the perfect car washing weather conditions all line up!

The above picture link shows the 3 solenoids that happen to be stainless Ascos but could be other 24VAC brands. One of the 3
Flojets is partly shown off to the left. ... if you plan & sketch you can have your wiring much neater than what this specific afterthought improvising shows. Maybe as neat as 2Biz's even
. The 24VAC low voltage is more forgiving when the inspectors visit us
! Since your portions that only have the air & chem manifolds must be similar to the rest of us ... I did not include that detail in the picture.
