SWG Journal
OK, enough about CH (but I'll still accept late votes: raise CH330 to CH350? Or leave alone?). Back to the SWG.
One thing that was challenging me was being able to find a SWG schedule (output and hours) that would co-exist with my solar schedule. The SWG schedule is a mostly consistent (x hours a day). Solar schedule, on the other hand, can sometimes be dependent on whether I think I'm going to swim at all (sometimes I won't heat the pool for a day), or if family is coming over (who want it warmer), or if I'll be swimming late evening, depending on how warm out it is. So sometimes allowing solar only during SWG hours is fine. Other times I don't want any solar heating to occur, to save energy. And then sometimes I want to extend solar hours beyond SWG hours. But that would mean I'd mess up my FC because the SWG would be running longer than it needs to.
Then I solved it!!
My miserly EasyTouch PSL4 has a lot of limitations. Scheduling being the worst. For some reason my PB gave me the lite ET, but he also made it the SPA version, though I don't have a SPA. I didn't like that, because the SPA controls and functions mess with my ScreenLogic interface and pretty much just get in the way.
Then during the winter, I found a great use for the SPA automation. I set SPA to come on during freeze mode (an obscure function of the ET), and that works great. It lights up a big ol' green LED on my Indoor Control Panel whenever in freeze mode. And it plots on ScreenLogics' History graphs when exactly freeze mode occurred. So now I like having the ET with SPA!
Well, that led me to my solution for the solar/SWG issue. For swim season, when freeze mode is no longer needed, I've reassigned the SPA functions from freeze to solar, but I set the SWG setting for SPA to zero!
Now my SWG runs during Pool mode (filtering mode) 8am-4pm. And my solar is scheduled to run during Pool mode as well. If it's a normal swim day, I do nothing. If I won't be swimming that day, I can turn off solar heating manually, on the fly, and it'll reset and come back on the next day. But if I want to
extend my solar heating beyond my SWG hours, I just hit the SPA button on my Indoor Control Panel, or on my iPhone (like if I'm out of the house), and I'll get solar heat until the sun goes down, but it won't mess with my FC production that day, because the SWG is set to zero for SPA mode. Yay!
Because I don't actually have a SPA, no actuators operate, so the water all flows through the pool, whether in Pool mode or SPA mode. The ET doesn't make the distinction!
All mostly meaningless to everyone here, but it is a testament to automation, and ScreenLogic. Two things I would not want to do without. Many here building pools struggle with the necessity of automation vs it's cost. And others swear they can run a pool fine without it. But I think there is a disconnect between what these people think automation is about, vs what it can actually do for you if you push it, and utilize all its capabilities. It's also a tip for those considering an ET. I'm not sure what models come with and without SPA, but if you have the choice, get SPA, because even if you don't have a SPA, you can use that component of an ET for all kinds of other things. And the ET allows you to rename "SPA" to something else, so it makes sense within my ScreenLogic interface what "SPA" mode is actually doing. I don't know if any of these concepts translate to Hayward or Jandy systems. Maybe somebody can make use of this idea for their own special needs.
This is all made very easy by the computer interface of ScreenLogic. A great add-on to automation. So "yes" to automation. "Yes" to ScreenLogic. And for me, it's still a big "Yes" for the little engine that could, my Indoor Control Panel!
BTW, it's not lost on me that the notion that anyone would discover any of my life-altering-advice in post #184 of a thread is pretty silly!
My only questions for anyone who might have braved it this far... because my SWG and circulation is handled sufficiently during my Pool (filter) cycle, when I turn on the "Solar No SWG" mode described above, I only need the pump to ramp up when there is demand for solar. If the pool is already warm enough, or the sun is going down, I don't really need the pump to be running at all. I have the RPM for this "Solar No SWG" mode currently set at 500RPM, to save on energy when there is no demand for solar.
So the questions: since I don't need the pump to accomplish anything, but it still must be running, is there any setting for RPM that is too low? Is that 500RPM setting hurting anything? Can I set it to
zero? So that it would be basically off until the solar demand needs its 2200RPM?
