First time poster. I recently installed a variable speed pump and am loving the incredible energy savings. I'm almost ready to open my pool for the season and opened the manual valve to get the water running up to the solar panels on my roof. What I noticed is that the pressure drops in the system and the sweep won't run at the (1500) RPM speed where I had it set. In fact the booster seems to shut down after a few minutes of trying to run when my Intelliflo is set to 1500 rpm and my Solar is open. In order for the sweep to run with the solar open I seem to have to put the Intelliflo to max speed (3450ish RPM). My first question: Is this common?
I'd prefer not to have to run my pump at max speed - it eats up energy like a Monday morning cubicle. Ideally I'd like to close the solar valve during sweep runs and open it again when the sweep completes.
My second question : What would be the best way to automate the system so that the solar valve closes in preparation for the sweep to run and remains closed until the sweep completes?
Note: I also have a Pentair CVA-24 and a Compool LX-220 which currently aren't working. (The board on the LX-220 is broken and the CVA-24 is stripped or something). I bought a pair of replacements off eBay, but before I hook those into the system I wanted to see if there's an elegant solution to my problem. The LX-220 does not appear to have the function of closing off when the sweep is running - it does have a sweep delay mechanism to prevent air from getting into the booster, but other than that it appears to activate the actuator based on temperature readings alone.
We use a lot of energy already at my house and in California the tiered energy rates are killing us. All extra energy I use costs me .36 kWh -- so running the booster and pump at max speed for 2-3 hrs a day could cost me like an additional $50-90 a month. If there's no way around that I might just go for one of those robotic cleaners which draw 250w. Over the long run it would save me money.
