carel mpxpro
having an annoying issue with a carel controller, fitted to a cold room with air on and off probes, no defrost probe. I'm trying to set room to control on 70% air on via parameter /4.
Room will only control on air off probe though, what am i missing?

Is the inlet probe working?
Extract from manual,
* intake probe Sr error: MPXPRO starts control based on the outlet probe

Yes, i've checked each probe is reading, also it would bring up an error on controller.

Found the problem, i'd mistakenly set RD2, put this back to zero and virtual probe works!
