I have a Compool CP3800 system, and I have noticed a couple of issues I wanted to bounce off the experts. First, I have noticed that in the past week, there has been a buzzing sound coming from the outdoor panel. When I unscrew and open the door, the sound stops. Secondly, I observed this past weekend that when it was time for the pool program to stop, the indoor panel showed that the pool was off, but the pool kept running. The only way I could turn off the equipment was by using the outdoor master switch located by the outdoor panel. In addition, if the equipment is off, I can turn it on with the indoor panel so it does appear to be communicating with the outdoor panel. Very confused. Thinking it's a relay, but if it is, how do I go about determining which one? Thanks, Dave.
