I'm dealing with an armstrong heatpump, my question I would think is simple but honeyell, and the armstrong dealer couldn't answer it.
The stat is made by honeywell T841A1059, however it was made specifically for armstrong,
the terminal designatons are R,Y,G,O,B,W2,W3,E & X which one is the common terminal
X or B for the LED lights if B then what is X?

yor help would be appriciated!
