Roger,

The moonlight is cycling on/off in sync with low power pulse when it night mode.

It started doing this a few days into installation.

Is it connected to 1 pump or 2? What should happen in night mode is moonlight comes on and the pumps stay at pulse speed. Keep in mind this is triggered by a photocell so any light hitting the photocell could cause it to go in and out of nightmode.
