I just installed a BMV-712 on a 300 Ah LiFePo4 battery in our motorhome. I love the features & flexibility of the unit, especially built-in relay I assigned to battery temperature to control a cooling fan. It could use a parameter to put back in ANY SOC after briefly powering down, causing a reboot of 100% SOC. This requires a full charging to get back in sync.
The "Real" problem I"m having, is that this unit is supposed to "cycle between status items", according to section 3.11.1 (page 20) oc the manual. I should be able to hold the "-" button for 3 seconds to initiate this. Has anyone gotten this to work?? I really need this advertized feature, as I can "see" the display, but not comfortably "reach" the display to switch between volts, Amps, SOC, etc. The button works for other functions though. My unit uses SW version 4.00, then 4.01 after firmware upgrade.
Thank you.
