    FMM Questions/Programming

    Hi all,

    Just getting back into the APEX game and glad to see there's a lot of cool new gadgets. I'm trying to get my FMM set up to control my RODI reservoir.

    Currently I have; 2x Optical sensors 1x Hi, 1x Lo water level sensor and a solenoid valve.

    First question, is the 24v port on the FMM powered by connecting it in link to other modules? Or do I need to use the EB 24V?

    As for programming, to have the solenoid closed is that considered the "on" or "off" position? My goal is to set it up so that solenoid allows water flow when RO level is low and stops when water level reaches the high point. What is the best way to accomplish this?

    Thank you for your time!

    You need to plug the FMM into a wall outlet to power the 24V port. Alternatively you can plug the solenoid into the EB832 ACC port if you don't want to use the wallwart.

    The solenoid will allow flow when ON and stop flow when OFF

    You might be an engineer if...You have no life and can prove it mathematically.
