Output value scaling for RS5000 PID

I've been chasing my tail for a couple of hours now, trying to get the output of the PID instruction to generate a value of 4095 for 100% output. I've set the scaling in the config for 0-4095 for all fields. In auto mode the output reaches 100% but this seems to be the CV as well. I can't find the CV in the PID array. The help file states that the output value is display only.

For MO, SO, SWM, and TIE modes the output is a suspicious 2.442 for 100% manual input value. Do I really have to scale externally?

Any suggestions welcome!

OK, I've found it: It's the really obvious dint called "Control Variable"...
