    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

    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
