Ok, Im at a loss now. SI/DI now works which was my initial issue. I did the factory default reset. Now I dont have a temp, which was working before the reset. When the unit is initially powered up and you go into the system status page, the temperature selection says "not connected". I have disconnected and reconnected all the plugs at the back of the unit and still get the same result. I got this unit last spring and it doesnt have many hours on it. Any suggestions?
