I'm trying to use the relay to turn off an accessory circuit only on battery state of charge, and not temperature. I see the manual notes referencing a CHRG mode for the BMV relay mode in section 7.3.1, which seems to exclude the temperature settings of the BMV-712 Relay Default mode.
However, when I tested the BMV-712 on CHRG mode, the relay still turned off with the temperature settings. I could not tell a difference between CHRG mode and Default mode.
Has anyone else had this issue? Is this a bug, is there another setting I need to change, or do I need to reset/reboot the system for these types of changes?
From the manual:
"CHRG
Charger mode.
The relay will close when the state of charge
falls below setting 16 (discharge floor) or when
the battery voltage falls below setting 18 (low
voltage relay). The relay will be open when the
state of charge is higher than setting 17 (clear
state of charge relay) and the battery voltage is
higher than setting 19 (clear low voltage relay).
An application example is to start and stop
control of a generator, together with settings
14 and 15."
