I have a new Orion tr smart 12/12-18 connected between a lead acid type charger and a new lifepo4 battery. The green on/off led is flashing and the app is saying “charging disabled “ and flashes every 5 seconds “remote input disabled”. The remote link is in place and if I remove it, it stops flashing and shows a steady “remote input disabled “. Should I just return the unit as faulty or am I missing something?
