I am trying to install a new digital thermo(robert shaw 8625-1) in my place, but I am having trouble. The old thermo was a Honeywell, but I am unsure of the model. The wires in my wall are as follows:
Blue
Green
Red
Yellow
White

The Honeywell unit has O,B,2,1,W,Y,R,G connections
-The 2 and 1 are joined together by one wire and the only other wires connected are W,Y,G,R(the blue is connected to nothing).

The new unit has:

R
C
W1
Y1
G
O
B
Y2
W2/E
L

When I hook up the wires to the new unit, the display does not turn on and the A/C does not do a thing. The only thing I can get to work is the fan. How do I hook wire this thing up? Please help.
