Apex flush valve code using osc

[Dburr1014]

I'm trying to use the osc code to flush my membrane 1 minute at start up and 1 minute every hour there after. I'm new to apex so just double checking. This is what I have. I'm also waiting for my float valve to arrive so the ato will be fully automatic.
Thanks

@SuncrestReef may be able answer your question.
In the mean time he has published many tutorials related to APEX which can be found here:

Thanks I will look to see if he has anything. I may have it backwards. The statement reads
On then,
OFF for a minute,
Then ON for 59 minutes.
My rewrite is correct I think, I just don't know if the last statement should be then on or then off.

You will need to split this out into two separate components:

1. The initial 1 minute flush when the RO unit is first turned on.
2. The ongoing hourly flush.

This will require the use of a couple of virtual outputs to track the state of where it is in the process:

[Initial_Flush] -- virtual output
Set OFF
If Output AT-RO-DI = ON Then ON
If Output Flush_Timer = ON Then OFF

[Flush_Timer]
Set OFF
If Output AT-RO-DI = ON Then ON
Defer 001:00 Then ON

Then change your physical output code to this:

Fallback OFF
OSC 000:00/001:00/059:00 Then ON
If Output Initial_Flush = ON Then ON
If Output AT-RO-DI = OFF Then OFF

(there's no need for Set OFF because OSC has its own built-in ON and OFF states)

The Initial_Flush will cause it to turn on right away when you start the RO unit, and will run for 1 minute until the Flush_Timer reaches 1 minute.

However, here's one small caveat with this approach. The OSC command runs every hour on the hour, so depending on what time of day you turn on the RO unit, the OSC may flush shortly after the initial flush or any time up to 59 minutes later. But after that it will continue once per hour.

Okay, thanks. My original code was right. I will see the virtual output section.
Thanks again.
