I have attached a temperature sensing cable to my BMV712 and it is reading the temperature off the battery. I have connected my mppt 100/30 through networking to the bmv and the controller is receiving the temperature. The controller is set to rotary switch 7 for my LifePo batteries and the low temperature cut-off is greyed disabled but showing 5c as the documentation says. However it is NOT stopping charging as I have tested this down to 3c. This is a VERY important feature for me as I live in the mountains of Colorado and we get cold. It is NOT working. Please advise.
