Installed about 2 years ago. I had to buy a 'two speed' relay for my automation system (JandyLink) when I installed it. Worked fine running at high speed for ~3 hours and then low speed for another 9. As title says, lately, it's been switching appropriately to low speed at the right time and then within a few minutes is back to full speed. If I manually push the control button on the JandyLink, it switches to low speed but again switches back to high speed.
I'm guessing since it DOES switch to low that a) the relay works and b) the motor works, only leaving my JandyLink circuit board as the culprit but wanted to see if anyone else had heard of this problem. Thx!
