Hayward ColorLogic 4.0 Installation Manual page 22

Lights occasionally dim and brighten
Generation 4 ColorLogic lights have internal thermal protection and will
automatically dim the LEDs if the light temperature rises to 70ºC or greater. The
light will go back to normal brightness as soon as the condition is corrected.
Lights are not found during the "Find ColorLogic Lights" operation.
This occurs if the lights are not wired correctly. The lights and Network Module must
be on the same power phase. Refer to the wiring diagrams on pages 24-26 for
more details.
Lights that are found do not blink during the identification process.
One common source of this problem is improper wiring. Verify that the lights and
Network Module are on the same phase. Refer to the wiring diagrams on pages 24-
26 for more details. Use the "Left Arrow" to return to the previous light and then
continue to identify the lights using the right arrow.
