Wiring help Honeywell TH6320

I've searched and searched and haven't found my particular wiring setup. I'm replacing an old Honeywell tsat with a TH6320 wifi tsat for my heat pump. I'm not sure where a couple of wires should go on the new tsat, the W1 and W2.

My current connections on the old tsat:

G - green
C - blue
R - red
O - orange
W1 - yellow
W2 AND E - white

New tsat options:

K, Y2, AUX/E, G, O/B, C, Y, R, Rc

Thanks,
Shawn

Good Morning. Your new thermostat will wire up very much like the old one.


G - green
C - blue
R & Rc - red
O/B - orange
Y - yellow
Aux / E - white

You must also configure this thermostat to match your system.

1 = 5
2 = 0

Thanks! None of the diagrams I found showed the W1 going to Y.

Some of the old Chronotherm Honeywell stats wired up like that.
