I have enclosed a picture of control. I can not find on internet how to adjust the speeds to determine if I have on slow. Any thoughts on where to find the info or simple explanation of how I can put on slow? Control is H193000 Balboa Duplex. Thanks!

It's self-explanatory.

Press
1 time - Low speed pump no Lite
2 time - Low speed pum + Lite
3 time - Hi speed + Lite
4 time - Hi speed no Lite
5 time - off

That's the manual part that you can activate as required - the rest is fully automatic.
