Programming Apex for Remote ATO

iko2thdk · Nov 24, 2019

Hi R2R Control Freaks, I have tried without success to follow suncrest reef’s advice on ATO using a second FMM controlling my PMUP from my RO reservoir. I don’t seem to be able to make heads or tails out of the switches and configurations that are available with the renaming process. Here’s a screenshot of my very crowded dashboard with I am sure too many tiles. Help, I’ve been at this for days!!!!

Let's see if we can work this out for you.

Connect each device as follows:
Rename the FMM module that's near your sump with the optical switches connected. Name it FMM_ATK. Let me know if you don't know how to rename modules, inputs, or outputs.
Rename the remote FMM module where the PMUP is connected. Name it FMM_PMUP.
Rename the two optical switches:
1. The lower one should be plugged into FMM_ATK on port 1. Name it ATK_LO.
2. The higher one should be plugged into FMM_ATK on port 2. Name it ATK_HI.
Rename the 24v accessory output on FMM_PMUP. Name it ATK_PMUP.
Be sure the two optical sensors and the ATK_PMUP tiles are placed on your dashboard.
Configure the ATK_PMUP output Control Type to "Advanced", enable logging, with the following program code:
Set the ATK_PMUP slider to "AUTO" on the dashboard.

Keep in mind, the ATK only operates once per hour, so if the water is low and it's not doing anything, don't panic. If after 1 hour it's not working, follow the troubleshooting steps in my ATK tutorial article: https://www.reef2reef.com/ams/neptu...torials-part-3-automatic-top-off-kit-atk.692/

If there are any items on your dashboard you don't use, you should remove them from the dashboard to eliminate clutter.

I hope this helps!
