Hi all. I installed a 2.5 HP dual speed motor to my WhisperFlo pump last year. It's controlled by a Jandy Aqualink system (rev M I believe) with Aqualink One Touch RS Remote. The Aqualink is programmed to run high speed for 1 hour and then switch to low speed for 6 hours. Last week, the motor began toggling between high and low speed every couple of seconds. Constantly switching back and forth. I try to override with the remote and it doesn't stop. I switch to spa and it doesn't stop. However, if I set the system to Service and use the manual controls at the pump, the issue goes away.
My assumption is that the problem is with my Touch RS Remote. It is old and beat up. Before I spend $500 on a new one, I thought I would ask for second opinions. Could it be the high/low relay or a short somewhere else?
