Thank you guys so much for posting this good information! It sure helped me get my customer's chiller up and running after replacing an EXV and the module. I just came straight to this forum as I usually do. I hate to say this but the manufacturers, especially Johnson Controls, Carrier, and Trane all SUCK when it comes to tech support, especially for us "outsiders" who do not work for them.
helps a lot to have the crimping tool and some extra plugs

Thanks a bunch good to have this
believe the new exvs are SEHI valves and the wiring should be as on p.70 of RLC-SVD03A-EN. EXV #1 wired Red to J4-5 Green to J4-4 white to J4-2 black to J4-1 EXV #2 red to J5-6, green to J5-5 white to J5-2 black to J5-1 I made a copy of this page and put it with the wiring diagram when upgraded to the SEHI from the SEO valves
Would you mind posting the new exv update instructions as a fyi. If not would you mind emailing them to me so I can through them in my memory banks if I have to do this on a few RTAA's under my supervision. Thanks
I am surprise that the new EXV's and board did not come with instruction or directions. I have the info.....6 years with factory Trane tech. next time don't CAP!!!!!
Thanks for the help. I got the info for trane this morring .
Dont think he heard ya Klove .... You may have to yell !!!!
Cant find any notes on this but will be out on a jobsite that i had this issue on this week and will check the wiring on it
