I would like to thank Neptune Systems for one again putting my entire system at risk by trusting their products. I have an FMM - Which was a great product till 2 firmwares ago which made the FMM a useless 'toy'. What good are flow meters that at will convert to optical switches? Then last week a new firmware - that 'should' correct the FMM issues. I followed all the instructions and did the updates -- But still not 100% reliable - So I have no programming related to the FMM's. This morning another user posted regarding his FMM shutting off last night. I checked mine, and in fact one of my FMM's had done the same thing. And this morning I had a "NEW" tile which was a Virtual outlet I had created 4 months ago. A few mins ago = I walk past my tank and say - What the &*&(* my main pump is shut off. My system is 1300g and I am running an Abyzz A200 - If I had working Flow sensors this should not have been a surprise - and in fact the system was designed to fix this issue should the main pump fail. The surprise was when I went and checked the Abyzz- the Abyzz is on but not pumping water. Stupid me purchased the Abyzz / Apex interface. The NEW Virtual outlet in Fusion this morning --- That's my old virtual outlet that was used to slow down the Abyzz for maintenance - Apex/Fusion converted a Virtual outlet a digital switch on the FMM. Yes the FMM that went offline last night, the FMM that shows as being disconnected currently - but has an active switch that shut off the return pump to my system..... I'm sure Neptune is going to put the blame on me and my complicated system--- I mean who doesn't know that it's normal for Aquarium Controllers to restructure, rename, redefine your programming while you sleep at night, all by itself.
