AUX1 - LOW BAT DISC Disc load based on bat volt

[CharliVN]

I need a little help on the topic:

I have my classic200 with 2079FW setup the AUX1 - LOW BAT DISC Disc load based on bat volt, when the battery get down to 48volt, I have it wait for 5SEC then dry contact turn on (neg side of the battery) to power one of external AB relay contact to turn on the charger (go from inverter to grid at 220v), what I like to see when my battery get full charge to 5x.xv, turn off the AUX1 (switch from the grid to inverter).

Do you know any way to do that, at the current time I have the time set for 5SEC hold for low bat voltage before the dry contact kick in, after it kickin stay there for 3600SEC Delay, that way the charger run for (60) minutes.

Waiting for some reply from expert.  Learn new thing each day, that is a good life.
