I have a T6 stat with correct ac voltage and correct dc voltage and polarity. The face plate doesn't power up. Any ideas?
What is your voltage on V+ and Vg at the stat? Not trying to be a smart arse, but is the pigtail plugged into the stat?
Live each day like it is your last, for one day you will be right!
Its around 17.70 DC and the pigtail is plugged in.
Sounds like a bad stat to me, not much more you can check other than your pigtail connections.
