I have an aqualink RS8, which controls the on/off timing of the pool/spa, fountain feature, solar heater and yard lights. 1 - the display reads "6520 rev hh" 2 - the spa has been turning on by itself 3 - the display occasionally does show the water temp. 4 - the display also shows program A and B active (I want to delete both and re-program to make sure they're aren't multiple device programs) Please help. Thanks.

If it's both lights and they are on seperate switches I would start by checking the GFCI and be sure it is not tripped and if it is you would need to find out why. Then check power in and out of the light module in your power center. If you can set the power center to service and turn the lights on manuley from there then it is programming but most of the time it will be something in the lights or their circut.
