I have an Intelliflo VF variable speed pump controlled through a Jandy Aqualink. I can program the Aqualink to control the flow of the pump depending on what other devices are in use. I am trying to figure out the optimal settings and was hoping to get some opinions from others who have experience with variable speed pumps. Our pool is about 28,000 gallons with the spa, has 1 just 1 skimmer, but 3 drains in the main pool. The main pump is a Pentair Intelliflo VF and has a Hayward H400IDL heater, a Pentair CCP520 cartridge filter, a Jandy PCL1400 chlorine generator, a Polaris 3900 on a booster pump, and a waterfall on its own pump. I want to program the pump for optimal GPM for the devices while being as energy efficient as possible. I've done a few hours of searching and I'm having a hard time finding optimal flow rates for these devices.
How many turns-per-day do I want for a 28,000 gallon pool? About 1.0 / day?
The electricity usage seems much more efficient at lower GPM, so is it advised to run the pump 24/7 at a low flow rate calculated for my turns per day to get the most efficient energy usage, or will running the pump slower for longer be bad for the pump? Or should it be higher for a period of time to make the skimmer more efficient?
What is the optimal / recommended GPM for a 400,000 BTU heater?
What is the recommended GPM on the main filter pump while the Polaris 3900 is running with a single-speed booster pump?
Since the waterfall has its own pump, do I need to worry about the GPM on the main pump?
Does the efficiency of the chlorine generator depend on the GPM?
What is the recommended GPM for the spa when the pool is in spa mode?
Anything else I should consider when programming the flow rates for the devices?
