Hi everybody and a good new year.
I have a problem with a Carel Master Cella controller connected to a walk in cold room.
The user complained that the evaporator fans do not run much of the time, not a problem says me, I will reprogram the controller so that the fans run all the time (except during defrost). So with Technical Leaflet in hand and feeling rather smug I proceed to hold the up & down buttons as per instructions for 5 seconds - result nowt. Plan B: Hold prog + up + down for 5 seconds to go straight to parameter folders. Result; zilch. I know that all three buttons work when pressed separately so I don't think they are faulty.
Does anyone know where I am going wrong, it should be so simple? Any help grateful received. Many thanks
