    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?

    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!
