can I bypass pump's controler?


I have a variable speed Hayward pump. my contoler lights on but doesn’t work, LCD is on but shows nothing.

I was thinking to bypass controler and connect the motor directly to the timer to use my multiple speed motor as a single speed motor. is it possible?

if yes how would be the wiring? there are 1red 1 black and 1 ground wire from timer and 3, 1red, 1blue,1 black wire from motor. picture is attached.
