I did this with some simple water sensor chips and float switches and I am assuming it would be even easier with Hydros and their solenoids. I extended my RO flush lines and put a solenoid on and set it to turn on/open for a set period of time and I couldn't see why you couldn't accomplish the same thing with a Hydros solenoid valve on a drive port!
 
The RODI Filter output type has a built in flush sequence. I think it runs for 1 minute when the RODI is turned on and for a minute every hour it is on. I use that output but do not use the booster pump output since I do not have a booster pump on the RODI unit.
 
I just have the manual one from BRS and I wanted to automate the flushing as I have a dual float switch (low level then full level) and it flushes for about 2 mins before it fills up the ATO tank. I might have to redo it and tie it into the Hydros when I get it all setup.
 
If it helps here is the RODI output I have setup for mine the Output turns on a solenoid that is actually the input feed to the RODI filter. The flush output is a flush valve but it is not connected to a drive port. I have not changed it yet to a Hydros solenoid. The inputs are actually the contacts on a relay. When the relay is energized it creates a dry signal on the input. If the relay is off it is wet. I also have 2 solenoids on the DI output one is to refill the DI reservoir and the other is to refill the mix tank. If either of those outputs turn on it will also turn on the output with the relay that will turn on the output below
