I recently replaced my power pack on my Maytronics Dolphin Oasis Z5 pool cleaner. I purchased a 9995672, my original power supply was a 9995671. My original supply had a light for when the canisters were full and I think another for a timer function. The new power pack has a selector for 3 modes; 1,2,3. Can anyone tell me that the 3 modes are? I think I may have lost functionality for my remote but I never use it or the timer anyway.
