I actually would do it differently...
I would put this guy in the smallest pot you can find, and try a slightly drier mix.
In this case, try using some small grade bark instead of the CHC and see if that would work better.
Place a humidity tray or a deep saucer with some sand or small pebbles in it. Put some water in the saucer, but don't fill it all the way up to the top of the sand or pebbles. Filling it halfway with water is adequate enough. Then put the pot with the plant in it on top of the saucer with sand or pebbles. The evaporation of the water in the saucer will act as humidity for the plant. You can also place some other potted plants around the orchid including using the humidity tray or saucer techniques to raise humidity. It doesn't really matter what kind of potted plants. It could be other orchids, or it could be a pot of Campanula or something.
Place in bright shade, and hope for the best.
I think you'll find that if the plant is strong enough, it will grow new roots without too much intervention on your part. Spring/summer are the seasons where they do most of their growing.
If it doesn't make it, then you'll have learned what not to do in order to grow a Promenaea.
While I still do not recommend growing Promenaea species/hybrids to those who are barely starting out growing orchids. In my limited experience with Promenaea xanthina, it also hasn't proven to be the most frustrating of all the Zygopetalinae.
My point being that I think yours still has a good chance of pulling through.
