    Finally installed home made automation to include variable position valve control.

    Hey Rich…that transducer looks pretty nice! And it’s also nice that you have a “signature” psi to keep track of the zones. Be careful on the “absolute” number of 13 psi. That pressure will change as your filter clogs up…or is cleaned. You might need to figure a way to use a differential...

    Arduino Solution for Failed Pentair Intelliph

    Hey Jack, I am following this as well. Some comments… I have found the muriatic acid (I use 32% in my tank) to be extremely corrosive around my buried acid tank. It has destroyed my buried tank hinges, a stainless steel temperature probe, and four “chemically hardened” Milone eTapes (at which...

    Effective Pool Cooling for Hot Climates

    Wow…that is a huge difference from the 93F you reported from last summer. I have the same problem in Phoenix with full sun for my pool from late morning and on…I have been debating/planning to add some sun sails above my pool for a few years. This is another potential “pro” for considering...

    Retractable, Removable Pool Equipment Cover / Sun Shade / Protection

    Joe, take a look at the first post pictures…the sun shade material does NOT extend over the filter and panel covers, so they get direct sun.

    Finally installed home made automation to include variable position valve control.

    Rich…I think the approaches we have taken towards automation are very different. My background is microcontrollers and so the approach I have taken is to design the pool controller (hardware/software) as a module that operates independently and directly controls the valves/pool...

    Finally installed home made automation to include variable position valve control.

    Only in experiments and for relatively short periods of time. Attached are the specifications for my intermatic actuators (see duty cycle)…what I am planning will probably exceed these specs. Similar to what you are doing, I am going to cycle my IFCS/walll return valve ONCE during the zone UP...

    Automated Testing

    I’m still in Pinetop so I’ve missed it all…but we’ve had some doozies here as well. Thanks for the update…ORP might work for the purpose I’ve had in mind.

    Finally installed home made automation to include variable position valve control.

    Rich…I haven’t updated that thread in quite awhile but plan on doing so at some point. I’ve made quite a bit of progress beyond that thread. I’ve been working towards a goal and have taken a lot of little steps but so much more to do and so little time, haha. I don’t know if you followed...

    Automated Testing

    Hey Ron @MyAZPool , I’ve been really hoping that you might be the “tinkerer” who finds out something useful to do with ORP numbers and higher CYA levels (I am running CYA around 60 but might eventually go up near 80-90). Like you and others, I plan on adding a couple of the Atlas probes but the...

    Finally installed home made automation to include variable position valve control.

    Hey Rich…nice! My setup also allows me to postion valves to any location and I use it in my scheduling and testing. It uses the same basic mechanism as yours (timing and relays) and I have found that the movement of the actuators is VERY linear and predictable based on the time that current is...

    Arduino Solution for Failed Pentair Intelliph

    Jack…this discussion is related, but not necessarily 100% relevant to what you are doing. Should be a fun project… https://www.troublefreepool.com/threads/stenner-pump-controller-automation.203338/

    Dynamic GPM Calculations

    Ron...thanks for the pointer to that thread...I had missed that one. I haven't really considered moving to the digital FlowVis...I think I am going to get accurate GPM numbers using the method that the pump guys have been helping me out with. But, I DO like the digital FlowVis results that...

    Dynamic GPM Calculations

    Hey thanks Mark. I was already looking at adjusting those numbers slightly to "match" my data. But, after that "gasket movement" on my FlowVIS, I am going to step back and make sure the FlowVis numbers are valid before moving ahead with this project. I really do like the idea of "one...

    Dynamic GPM Calculations

    Hey Mark...I found a problem with the spreadsheet I posted. There is a gasket on the FlowVIS check valve that had worked itself loose in a couple spots. It was dangling "out" on a couple portions of the paddle that were near the "end" of the paddle. That led to "increased GPMs" being reported...
