long duration apex timers (1 Viewer)

If I wanted to run my RO boost pump for 2 days once the blue button is pushed how do I set the programming statement for the timer?

You can set a feed timer to a max of 18 hours. You can then add up to 999 minutes delay in the If Feed command for another 16 hours. That's as long as you can set an on-demand timer.

What about a latch timer like they use for the DOS manual water change using two different virtual outlets? You could effectively do 16 hours on each VO.

could you expound on this? I am not very good at the programming.

So it works like what Ben said, you would create 2 virtual outlets naming them however you want.
First out let would be programmed with;
Set off
If blue button 000 then on
Defer 999:00 then off
Second out let would be programmed with;
Set off
If output (first V.O.)= on then on
Defer 999:00 then off
Pump would be programmed;
Set off
If output (second V.O.)= on then off
Defer 000:00 then off
You can adjust the last defer statement to 999 for an additional 16 hours making it a48 hour timer.

Thanks that makes sense

The thing I’m not sure about is if the apex will reliably respond to a momentary switch, when used with a feed function, it programs the feed function with a 1 minute timer. So if you are using a break out box and a switch you may need to hold it for a second or two.

yup, I'm not using the feed function just the button with a break out box. The button is near the pump so I usually hold the button till the pump kicks on.
