Sreenlogic 8; Aux valve B to aux 7 relay to 24v sprinkler valve...help.

You would be using the valve b. You will have to go into settings and bind it to a circuit feature. There is no polarity on the sprinklers solenoid. I forget which two lines activate first on the valve port you can test red and white enable button and if you get 24vac that’s what you want to hook up to. I think @Jimrahbe is more versed in the actuator workings and voltage of each line. I usually just replace the whole actuator so I don’t remember what color activated first. Maybe he has some insight.

How do you plan on knowing when/how much water to add? I have an in floor cleaning system that pulls from one skimmer. When the pool water gets just slightly low it starts sucking air from the volume of water it is pulling. I installed one of kona labs autofill sensors. I did run the power coming from the autofill to the actuating valve through one of my relays in my easy touch so I could monitor how long the system was running when I wasn't home and so it wouldn't be masking a potential leak. I simply run it as a timer function. They have an online version that I wish I would have gotten-would allow you to monitor quite a bit from your phone. I don't have any affiliation with Kona Labs-was just thinking this might be a good addition for you since you said you would be gone for months at a time.

Just a note on irrigation valves - they are not foolproof. They are controlled internally by water pressure differences across a rubber bladder. The solenoid simply opens or closes a small orifice to allow the pressure across the bladder to change and water to flow. There is a hitch though - debris can get caught on the bladders sealing surfaces and cause the irrigation valve to pass water. This typically shows up as the lowest irrigation emitter on the line “weeping”. In a pool application this would cause the fill line to run continuously with a slow fill of water. Without a level sensor to cut power, a weeping irrigation valve could overflow the pool if no one is paying attention.

Hopefully you have someone looking in on the house while you’re away.

Be careful with the pre-named circuits. They are sometimes designed to work in ways that are unusual. Use a CUSTOM NAME for a GENERIC circuit to control an AUX relay. For example, I thought using the pre-named circuit "AERATOR" would be a good idea for something I was doing but, as it turns out with Pentair (il)logic, the canned AERATOR feature activates the SPA return valve so that water is pulled from the pool and sent to the SPA jets ... ok, that makes some sense and some nice bubbles. BUT, when in AERATOR Mode, the SWG is also activated AND you can run the heater .... so AERATOR will push all the water through the SPA jets, heat it and chlorinate it ?!?!!! I discovered this is the most unpleasant of ways - I was sitting in the spa with the aerator feature running just relaxing and it started to become hard to breath occasionally ... my IC40 was set to 60% and when it would turn on, some of chlorine gas it was generating was getting mixed up in the air bubbles and coming out of solution all around me. My wife happened to walk over and she said, "What the heck is that chlorine smell??" I hadn't noticed it much because I was sitting in it and it was building up slowly around me. Because the AERATOR feature runs the SWG in POOL Mode (full output), the amount of chlorine produced can get very high or at least high enough to cause breathing difficulty.

So I honestly am not sure why Pentair has that feature but I assume it's trying to do something useful with lots of chlorine and outgassing ... suffice it to say, I don't use that feature anymore and I created a custom circuit name with the feature set as GENERIC for what I needed...
