Tunze Osmolator Universal 3155

I have had my TO for less than a year and have never had a problem. Just recently the "too high" and "level" lights stay on together even though the water level may be level, or actually too low. I have moved the eye up and down to check it, I have unplugged and plugged it, check the connections, I'm not sure what is wrong (but manually replacing the water is getting old). Any insights would be greatly appreciated. Thanks!

Roger, any advice would be greatly appreciated. Thanks in advance for your help.

I plugged it back in and just the "too high" light stays on (even though the water is below the eye).

Too high means the float is raised.

The optic sensor only relates to the green or yellow lights, for level or pump on. The float is an override if the optic sensor fails and it triggers the red or too high. Is the float possibly installed upside down, being affected by a magnet or raised?

 

[cvsailer]

Roger, thanks for the response. I checked the float and it is not installed upside down, and it's not in the up position. I also removed the magnet and played with the float and nothing changes.

Here is exactly what happens when I plug in the unit:

1. The green "level" light comes on for around 5 seconds (not blinking)
2. Green level light goes off and no lights come on for 5+ seconds
3. Then the green "level" light comes on (blinking) along with the red "too high" light (not blinking)
4. After around 5 seconds the green light stops blinking and stays off and the red one stays on

Any thoughts on what could be happenind? Thanks again!

That is an odd one, did you add any new equipment or relocate the controller? It sounds like an magnetic interference issue.

 

[cvsailer]

I recently moved the location of the tank (across the room), but the setup is identical and no new equipment has been added. If there is some type of interference what do you recommend I try to attempt to rectify it? Thanks Roger, I appreciate the help.

 

[rvitko]

Try the controller in another room, like the bathroom or kitchen using a bowl of water or a sink to activate the sensor. See if it then works normally. If so, we can be sure it is an interference issue.

Sharing an outlet with a wireless device, being near a ballast or driver or zipties of wires together are probable culprits, the sensor wires should not be bundled with any other wires, but they can be ziptied together.

Interesting, thanks. I will check it out tonight and let you know how it goes. Thanks again!

Roger, after several tests to figure out what was wrong I finally noticed a small cut in the gray wire. After reattaching the cut wire the unit is working correctly again. Manually replacing the evaporated water was getting old real fast!

You are welcome to send it in, I can replace the float if you prefer.

I have similar problem with this issue. I will open another thread.

Thanks for the offer Roger. I don't anticipate it but if I have any further issues I will get back to you. Thanks again!
