full ac control without AC pressure sensor

Still set up an analog input as a AC pressure sensor but you don't need to connect a pressure sensor.  On the analog input setup screen set the hi and low error volts so that it is in error condition full time (say both at 2V), then set your error pressure value to a pressure that will allow your system to run (ie somewhere between your low and hi pressure lock outs).
