My review of the new Neptune ATO

Thanks

Gee I hope they just sell the float holder. I'm looking for a float holder ( magnetic) for my floats

Me too! it's really well put together. I want one for my ato reservoir.

Is the FMM powered by the EB832? Or is that extra power supply still needed even with the new Apex?

Bob Escher · May 24, 2017

From what I could see is that it can be self powered, powered by a eb8 or the eb632

You will have a power supply to drive the PMUP that connects to the FMM. I've got mine in the EB, but it would work just fine not in there since you can control all the same stuff without it there other than resetting the FMK (I've only done when we switched from connected to stand alone during the beta.)

Thanks, it appears that the power supply for the FMM is only needed if you want to use it's 24V port. I'm hoping to plug the PMUP into the EB and free up a power outlet that my Tunze takes today.

jasonamyers · May 24, 2017

You'll have to do some custom programming to make that work. Since that cable is the only one from the FMM to the PMUP. The FMM normally uses the power on its internal 24V port to turn on and off the PMUP. You'll have to make it point to a different port etc in the programming.

Is there a sensor in the PMUP that shuts it off when the float valve closes off the water line and there's back pressure on the pump?

Where did you get the mount for the 'low level' optical sensor? I want this kit as an ATO for my ATO reservoir and have been struggling with how I'm going to mount the low level sensor.

Just ordered mine... can't wait to set it up [emoji48]

There are two optical sensors that go with the float and control the FMMs desire to run the PMUP. It's part of the ATK. Depending on how you set it up, there is also Fill-IQ that limits runtimes etc for the pump when the opticals have failed and the float is holding it back.

So the OS-1M is an optical sensor with a magnet mount just for this.

I've been testing the ATK for awhile and can answer that for you. Both opticals should turn off the pump before the float is ever engaged. If both fail due to buildup on the sensor or a bad connection the float will rise and stop the FLOW of water. The pmup will continue to run because it thinks the sensors aren't triggering it to shut off. There is however programming built into the standalone mode and apex connected mode that prevents the pump running forever. When in standalone mode IQFill will take over and shut off if the pump runs for 2-3 times longer than it has in the past. If all previous auto top offs took 30 seconds, the pump will turn off after just over a minute even if the float is engaged because it knows something abnormal happened. When connected to an Apex similar programming is added when using Task setup to prevent the pump running longer than 5 minutes (This can be shortened if top offs usually only take 20-30 seconds).

Programing is built into the ATK that also limits intervals of top offs. It will only top off once every hour if the sensor is low / failing. This keeps it from running continuously and retriggering false low readings.
