I picked up a RKE and have the digital readout of the manual, read the thing over and over, and I still have an error message at the home screen. I'm only using the temp probe and ph probe, and on the pc4 I only have a blue line 500w heater to channel 4 and on the RKM-SL1 I have everything according and the wire from BUS 1 to PC4, sounds confusing but bare with me please, any thoughts.
