My soap use is first color goes fast, second color gets some use, third color lasts forever.
A customer shared his frustration with color 1 consumption...
“It blows through the pink foam and barely uses the blue. I just use one color now.”
Sure enough, his 3 Hydrominders were all supplied from the pink foam jug.
“I can fix that for you.” I boldly promised. (
I left out the “I Think” part.)
After some tinkering with my PLR software, I was able to solve the issue…A resetting 3 Bit Shift Register does the trick.
The controller now energizes the next color solenoid when the system comes off idle.
It also delays pump activation for 2 seconds to prove the customer’s selection.
He’s happy with the equal product consumption rates and I now incorporate that feature in all my Tri-Foam PLRs.
