Great info, back_yard_lap_pool. Are both Stenner setups chlorine? Why two? Can you share why you went Stenner instead of SWG?
Are you running two completely independent setups, or do they share some plumbing? Your pic shows both injectors in the same pipe. Are those the chlorine injectors?
Did you have to go with the Intellitouch over EasyTouch because of the complexity of the "two of everything?"
Just looking to give the OP a sense of what they're in for... Any other pics to share? Would love to see the whole setup...
That is a shot of half the chem system - there’s another box on the left of this with a 3rd tank. One quill on the 2nd picture injects bleach, and the other injects acid. (Didn’t mention the acid for simplicity of the first post.)
I went with intellitouch i10+3 at the recommendation of pool contractor for current automation and future automation flexibility.
We went Stenner because we had a cheap source for bleach and there is a fair amount of stainless equipment around the pool that I was concerned would rust faster around salt water... I kind of weighed the cost of replacing swg’s every few years against just buying bleach and decided bleach was simpler and roughly the same cost (assuming 2-3 year lifespan on 2 large swg units).
The setup complexity is largely due to the spa, lights, automated valves for water features - but if the OP is keeping it simple (pump, filter, sanitizer), most of the piping, valving, wiring and automation won’t apply. Here is a quick shot of the equipment pad area though for reference.
