I recently replaced my single speed WhisperFlo pump with a WhisperFlo VST. I wired it into the comp port and thought I had my EasyTouch set up correctly. The pump comes on and runs as intended normally and operates correctly under freezing temps. But when I switch to spa the pump goes to zero speed and stays there. Any ideas what I have missed in my set up. I don't have screen logic so I am programming it from the EasyTouch panel.
 
You need to set a VS speed for the spa circuit in the pump settings.
 
I did read that online searching for causes, but when I look at my circuit it doesn't show an option to set a VS speed. I wish there was some instructions online.
