So, I would set up the VS timings, and then just use my control panel for off/on? I’m just assuming that it needs to run higher when in use.
I keep mine on 24/7. Filtration works better with low speed. And it saves money.
21.5 hours at 1200 RPM - Fast enough the SWG works - 55-60 Watts, 40 GPM (1.3kWh/day) 51,600 Gal/day - Also VERY quiet
1 hour morning @2800 RPM - Skimmers work well - 700 Watts, 100 GPM (0.7 kWh/day) 6000 Gal/day
1 hour evening @2800 RPM - Skimmers work well - 700 Watts, 100 GPM (0.7 kWh/day) 6000 Gal/day
1/2 hour noon @2800 RPM - Spa mode circulation - 700 Watts, 100 GPM (0.35 kWh/day) 3000/Gal/day
Total is 3.kWh/day. Notice, the 2.5 hours at high speed use more energy that the entire rest of the day. And I circulate the pool 67,000 Gal/day. And the pool is VERY clean.
Running my pump 24/7 allows me to keep the SWG set to only 22% during the summer. It is running 10% in the winter (so far).
I still have a 2 pump setup (Primary and "boost"). My Boost is a 3/4 HP power hog, but it can be controlled with my remote. If I manually turn on the SPA, I switch the boost pump on and the heater works. If I heat my pool in the fall/spring months, I do the same.
The alternative is to run the pump a bit higher speed so that the heater switch works anytime (1500 RPM, 125 Watts).
Also, at least on my pump, are 4 buttons. These are programmable for speed and duration. I have them setup for 2400 RPM for 3 hours, 2800 RPM for 3 hours, 3450 RPM for 3 hours and 3450 RPM for 12 hours.
The Doheny pump has only 3 speeds, 1500, 2400 and 3250. And it has 2 modes, 16 hours/day and 24 hours per day. I expect you will get similar energy consumption at the same speed, 1500 should be about 125 Watts, 2400 about 450 Watts and 3250 about 1200 Watts. This will vary depending on your filter, how clean your filter is and the design and size of your piping.
Savings: I "thought" I had a 1/2 hp main pump. I in fact had a 1 hp pump (1776 Watts!). I was running my pump 16 hours per day (6AM to 10PM), because I was told this was the thing to do. I was using 28 kWh PER day with my main pump. @8 cents per kWh, this is was about $1200 per year. Yep, I was an idiot. ANY pump would have payed for itself in one year.
Lets say you run 8 hours per day and pay 10 cents per kWh, your op cost of a 1 hp pump is about $775/year. If you run 24/7 on the ECO program, your cost will become about $110 per year.
