Martina Posted January 31, 2021 Report Share Posted January 31, 2021 I bought a home that has a portable Apollo Explorer Hot tub/Spa (2010/2011?). I was trying to program the filtration cycle and when I push the Program button it gives me the Sett display, but the next display says Fd 1, and then FF 4. What are these numbers and how can I program filtration duration and times of day? Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted February 1, 2021 Report Share Posted February 1, 2021 Fd=filter duration, how long it filters. FF= filter frequency, how many times per day it filters. It will start the first filter cycle shortly after it is powered up, so to set the "time" you need only reset the breaker when you want it to start. 1 Quote Link to comment Share on other sites More sharing options...
