Reprogram a Carel ir33 controller
I have replaced the Carel ir33 controller on my Avantco CFD -2FF freezer and I can not get it to work. The controller keeps giving me a rE; EO & E1 error code. I have tried to reprogram the unit but it will not hold the changes and returns to the error reading. I am using the probes that came with the replacement unit. I have spoken to the US agent and he has advised me to change these two settings /p & /A2, however I am unable to access these parameters when scrolling through its program menu.
Has any one an idea of how to solve this issue?
