I just plugged my control panel in for the first time to see if everything powers up, and remarkably it did. My question is this, I dont have the RTD yet, will it work for my boil kettle on manual without any type of probe? It powered up and blinks numbers and letters alternately on top and bottom, Is this normal? I havent had a chance to go through the instructions yet for programming, I put them somewhere and need to find them.
