7095 controller on night mode issue

[mfinn]

I have a 7095 controller that I have setup for night mode.
In the last week or so I noticed the lights that indicate which pump is on the highest flow rate are still switching back and forth, even after the tank lights are out.
Are the lights suppose to go to the lowest level along with the pumps?
I could just stick my hand in the water to see if the pumps are still going from high to low, but that would involve opening the canopy and exposing the sensor to light from the room.

Make sure night mode is on as indicated by the green LED next to night mode. Make sure the photocell is in a dark place to actually activate night mode. What should happen in night mode is the pumps stop pulsing and the pump stay at the setting of the bottom most knob on that channel for the duration of the dark hours.

The green led light is on and the sensor is in total dark.
It was working before the power supply on one of the 6105's went out.
While waiting for the temp power supply to come, I used just one pump and that's when I noticed that the lights were going back and forth from high flow to low flow.
Now that I do have a temp power supply on it,,, it still doesn't go into night mode.

Does the moonlight work? If not I suspect it is just coincidence and water entered the photocell/LED assembly and resulted in a short.

 

[mfinn]

The moon light does work.
I have the sensor elevated so it would be impossible to to dip in the water.
The night mode did work up untill the power supply ( which came today. thank-you) went out.

That is very strange. I still don't think one issue caused the other, more likely there is something else at play. Would you please open the 7095, just undo the four screws on the back and check if your photocell/LED is the plug in type or the solder in type? We changed to a mini plug in late 2008, this is an easy DIY replacement in this case, the older solder ones will typically have to be sent in.

 

[mfinn]

Unfortunately it is the soldered type.

 

[rvitko]

I know it is a hassle but if you send it in, I can replace it.

 

[mfinn]

Will the 6105's work without a controller?

 

[rvitko]

Yes, they will run without a controller.

 

[mfinn]

I suppose I could get a couple timers with multiple on/off settings and have them alternate flow 4-5 times a day , then have one off for the night period, then send in the controller.

 

[rvitko]

The down time wouldn't be long, I have the part on hand at the moment. I think you could also just run one pump or turn them both down using the potentiometers on the junction box.

 

[mfinn]

turn them both down using the potentiometers on the junction box.

not sure what that is or where.

 

[mfinn]

Ok, after a little light reading in the manual, I found the adjustment potentiometers on the junction box.
Can I assume that I can get the full range of flows ( that I can with the controller) using this adjustment?

 

[rvitko]

Yes, you can get the full range the controller offers, but it is very important that this goes back up to 100% when a controller is reconnected.

I'll get it boxed up and sent in to you this weekend

I found a timer that has 48 settings. I can set it so one pump is on for a 1/2 hour and then off for a 1/2 hour, with the other pump on opposite cycle
