tunze osmolator 3155 alarm

[Neo Jeo]

Every time I turn my return pump off the water level rises in my sump then alerting my auto top off alarm to go off is there a way that I can a disable that auto top off alarm or only have it come on when the water level is too low ? tunze osmolator 3155

I don't believe so. All it says in the instructions is to position the sensor high enough so that turning off the return pump doesn't trigger an overfill alarm.

You can open the 5017 controller box of the 3155 and turn off the audible alarm. It will be fully off however, as there is no way to selectively choose when you want to hear the alarm, be it a power restore or water level alarm.

If I put it high won’t add too much water in my tank ? I have a r-200 sump

It would, but how full does your sump get when you turn off your return pump? I'd turn off the pump, and set the sensor slightly above that.

Unless would it be good to have a lot of water in my sump and just raise my protein skimmer off of the floor with something ?

But if I bring the level of water to when my return pump is off and I turned my return pump off again I would be afraid that the sump would overflow . Here are pictures of when my return pump is turned off

 

[Neo Jeo]

It gets quite full but if I fill it up to that level without pump running and turn off then I’m going back to square one where the water is going to raise over the sensor again

Lets ask another member of #reefsquad hopefully someone in the group uses this top off and can provide more insight

There should be an extra magnet. Mount the mechanical float switch (high water sensor) using the spare magnet above the water level of when you turn your return pump off.

I use a small media bag, draw string type and put a small rock or anything with a little weight. Just put the drawstring on the float whenever you turn off return pump. Or leave it there full time

If you are using a controller, e.g., Apex, you can program it to turn the ATO off when the return pump is off. Add a 15-30 min delay on the ATO when the return pump is reenergized so the sump level has stabilized first.

High water level float switch will move up wards on the mount. You can even buy an extra mount to so it can be mounted higher in the sump if needed.

The Tunze will not add too much water to the tank if you have the float switch high. The water shuts off when it reaches a mm or so above the level sensor tip. Turns back on when it goes below the tip.

In regards to your alarm issue. You could always just shut off the Tunze when you shut off your return pump. Then wait until your water level equalizes (after the return pump is back on) before turning the Tunze back on.

I disabled the high water alarm and mine still beeps when turning back on from a power restore. Does it 6 times a day after my Apex shuts it off for a half hour after my Kalk Reactor stirs.

 

[reefwiser]

That is normal when you turn the power off of the unit it will beep.

So the high water alarm is only activated when the mechanical float switch is engaged ? If that’s the case then yes it comes with an extra set of magnets and I could move that higher . And that will solve my issue

Also I do not use an apex .

Yes when the float switch is engaged the alarm goes off and it should also shut off your ATO pump. I could be wrong but I believe it is more a fail safe in case the water level sensor fails and the pump does not turn off.

If that’s the case then it comes with an extra mount . I’ll turn the alarm back on and move that safety switch up higher then my water level will be when return pump is off! Thanks guys and gals

Yup, you should be good to go!

It’s gonna work! Did not know that was a thing. Thanks man
