Auto RODI production - How to programme

Hi all.

I have an RODI unit with two solenoids. One is powered in the Plug bar and connected to the mains water supply and one is connected as a bypass to the flow restrictor (to act as a flush).

I plan to use the Min Max function to have the plug bar turn on the RODI unit with a low level indicator on the fresh water tank.

I also want to have the flush activate anytime the mains is opened (for 30 seconds)to send the first bit or RO water to waste (as it is usually very high TDS). How would I programme this?

Also can't find many instructions on how to mount the the float switches, the magnetic bar wobbles left and right very easy.

Thanks, Joe.
