Can you please try to answer me one question. I am servicing thermo king V-500max, and I changed the ***** form r134 to r404. It is possible to change that parameter in a computer with a in cab controller? I have to change that because unit is shutting down because of the difference in the pressures of r134 and r404.
Thanks for your answer
Change the hp switch and cond fan control switch
expansion valve is different as well.
Everything is ok. The computer was damaged so I had change it, but the software on a new computer was set tor r134. My system is working wit r404, so I have to change the parameter on a computer from r134 to r404. Probably I have to install new software on a computer.
