I am replacing a old mercury thermostat with a new digital Hunter thermostat. I cannot figure out where the wires from the wall go on the thermostat. I have followed the instructions in the manual, but I understand that I might have a couple of wires the wall I might not use. Coming from the wall I have:
R
Y
B
W
G
O
T
X2.
On the T-stat I have:
RH
RC/R
Y
G
W
L
O
B
A/E W2
Y2
C
A

Can someone PLEASE help me with wiring this ?
Thanks
