The setpoint should be compared to the EU range, which in this case is incorrectly configured. The PID block scales the input PV (0-4095) to Engineering Units, and then calculates the error from Set Point. (Also in EU). The print outs show EU of 0-4095, it should be what ever the input scaling is (assume Type J) then 32-1400F.
