Topic says it all. I have a REC ABMS running latest 2.92-2 firmware for a split bus.
Batteries are 4s4p 280Ah cells.
The charge side is using a pre-charge 3.0 module which controls a Blue Sea contactor. Charge temp is set to 3C and above in the ABMS settings.
The discharge side controls a Victron 220A battery protect.
Everything works properly except being able to specify a lower temp to enable discharge. Right now at below 3C both sides disconnect.
I want to run the discharge down to -10C as still inside the cells "safe" range.
@John a probably solution is to use output: relay1 and opto2.
Under task you can make different settings. See screenshot from task menu.
We are going to need to get REC head office to give us some input on this one. They are closed until the new year but by way of this post I am letting them know.
Any ideas on this one Tine?
Thanks,
Rick

@Rick Thanks! I was going to email them directly but knew it was holiday season so tried this forum. Happy holidays!
Hello John,
Did you try to set in task, "7" on, for the charge bus.
Load bus, I expect don't switch off at that temperature. It don't solve all your question, but the system will work better then when switch off both.
Charge current is only set to 0 A when the temperature goes under the Under-temperature for charging. Contactors are ON unless you select them in the TASKS for the charge relay 1.
