We have an inground hot tub that is experiencing an issue.
Everything has worked fine for years until we did some home remodeling and the electricians reconnected the spa control (on the wall outside) to the control panel at the pump.
Now everything works but the jet (high speed) doesn't work.
I have scoured the web for any schematics with no luck.
I am hoping someone can help me troubleshoot this. I am an engineer and am comfortable working on this, but it is difficult when there is no reference info.
The control panel is a Catalina RC4a
Thanks - I am crossing my fingers that someone will help us out!
