Rewiring Honeywell T841A1423
Son-in-Law took out the old Honeywell T841A1423 thermostat for a 2.5 ton split airconditioner/heat pump and installed a Hunter 44110 before leaving for Iraq. Hunter 44110 worked on heating but not on cooling. Have that figured out, but need to reinstall the original Honeywell T841A1423. Problem is I don't know where all the wires go.
Coming out of the wall are six color codes wires.
Yellow
White
Red
Green
Orange
Brown
I figure that:
G - green wire post
R - red wire post
E - no idea
L - no idea
X - no idea,W2 - White but there is also a W1
B - brown post
Y1 -yellow post
O - orange post
Question: This is a single phase heat pump unit. Do I just reconnect the white wire to W1 or to W2. There was no E to W2 jumper. Sincerely appreciate any help you can give.
