Blue Line Tsunami Wavemaker Directions?

[PassDaReefer413]

I recently received a Tsunami wavemaker in a trade. I understand how it works, but it did not come with any instructions. The P1&P2 knob controls the first two powerheads, and the P3 controls the third. and the Feed knob controls my main pump. This I know, but how exactly is it timed, what is the gray button for lol, and does it just switch from P1&P2 to P3, or is each one indepently operated and will switch on/off independently.
My old wavemaker was nothing like this one and I am extremely confused. Their website offers no help and I couldnt find anything online.

Also, does anyone know why an account would be able to be signed into, but wouldnt be able to post/search/etc. I havent signed in for a couple months, but why would I all of a sudden not be able too?

thanks and have a great day
