MS4448PAE not communicating with ME-RC50 or ME-BMK
I have a MS4448PAE installed with a ME-RC50 and a ME-BMK that will not communicate. I have 14.2 DCV on both cables coming from the inverter to the devices. When I connect the remote, and following the power up self-test, all of the LEDs turn off and “No Inverter Com” is displayed. Also, when the BMK sense module is powered up the LED ends up blinking red. I contacted Magnum Tech support and they we not very helpful. Thank you.
