Sharyn, I think you did the right thing moving the phals to higher temperature and light since they don't get direct sun.A shock of cold would hurt them.
I often move my phals to give them the light they need: on cloudy days next the window, on sunny days away from it in a shady place and some filtered sunshine. I try to protect the blooms from sun. They seem to accept happily the disturbance...As about humidity, now I have not much with all the heating, there is no bad consequences .
