Switching to GLAS thermostat

Most of this is pretty cut and dry, but there is some difference in labels on the 2 Tstats.
in FL ac unit outside w air handler and electric heat
I assume Y = Y1
R = R1 ?
The old tstat has an O/B wire, the new has an Aux is this the correct on to use on the new?

Old is Honeywell th6220u2000
new is Glas

Please post a picture of the old wired thermostat base.
R does not = R1...... R would be Rc.
O/B = O

Y - Y1
G = G
C = C


O/B = O
W2 = W2
R=RC


OLD = NEW

Correct?

It's not W2...... it's AUX. You use the inside labeling for a heat pump.
So on your new stat..... what was W2/AUX will now be W1 on the Glas.
