After seeing a post yesterday regarding upcoming federal regulations requiring variable speed pumps in July 2021, I started to do some research into the topic. As part of that I read the Intelliflo user manual to get a feel for how they can be used and programmed. I also reviewed pump curves for that pump, including some that actually showed electrical power required. This was in an effort to predict how I'd use such a pump, at what levels I might run it and what energy savings I might realize.
There were two things that I couldn't find that maybe someone here can help me with:
1) The Intelliflo manual mentions that once the time is set in the controller it will remain until changed or until the pump doesn't see power for about 96 hours or so. It sounds like the controller has a volatile memory but a back-up power source (capacitor mentioned) that holds the time setting and probably the user defined settings/programs as well. Is this true, does the controller lose all settings and not only the time setting with a prolonged power outage? Can I assume if settings are lost they go back to factory default settings?
2) I was able to find an Intelliflo pump chart that shows electrical power. This would allow someone to estimate electrical power use knowing where they'd likely run the VS pump based on the performance of their present system/pump. However, I couldn't find any pump curves showing electrical power for my Pentair SF-N1-1A (340038) pump or any single speed pump for that matter. At this point I can't estimate my present pump power consumption aside from calculating my present power consumption by measuring line current when operating. Has anyone ever seen a pump curve for this single speed pump that shows electrical power?
