24V to visionPRO for constant backlight
I'm considering running yet another fresh run of wire to my t-stat so I can have the constant backlight feature. My understanding is all it wants is 24V AC which I expect I can pull from the transformer that came with my WM EG-45 boiler by replacing my two wire run with a 3 wire run. I have a spool of 18AWG X4 handy so I might just use that.
My concern is that maybe this actually needs filtered DC and I missed a detail?
