Trying to switch from a White-Rodgers heat pump thermostat to a Honeywell RTH3100C. The wires on the old thermostat were connected as follows.
White was connected to W2
Red connected to R
Yellow connected to Y
Green was connected to O
Blue was connected to C

The new thermostat has the following
E Aux Y G O L R B C

Can anyone help me with the way this should be connected to get it to work
