I have the 7094 Controller with the photocell and 2 Turbelle 6110 pumps. After installation today, the photocell does not seem to operate. The controller continue switching between A&B after the lights are off. How sensitive is the photocell. I have an open refugium under the tank with 24/7 lighting and some light escapes . Even when I cover the sensor with my hand nothing changes (that is one pump should work at low speed).
Do I have a defective photocell. How can I test it?
