Rinnai RUCS75i Fan Frequency Hz Question (Newbie)
So I am a newbie to the site and tankless water heaters and I am fascinated with the technology. I self-installed a Rinnai RUCS75i with a Control-R wifi controller. The app provides ability to collect codes, which includes Fan Frequency. Can I calculate BTU's from fan frequency Hz?
Sorry if this is a stupid question and my be why searching this forum failed to produce anything.
