Lennox heat pump old wiring - A, X, M, L, F, R, M2, E, a Red & Green wire with no label & a terminal labeled E with nothing attached.

Honeywell RTH7400 wiring - C, G, Y, O/B, RC, R on the left side & AUX, E, L on the right side. This is labeled "HEAT PUMP"

Where do I put the Lennox wires on the Honeywell RTH7400??

Mistake on the Old Lennox thermostat labels...

It is labeled - A, VR, X, M, L, F, R, M2, E and a terminal with no label with a red and green wire attached. The E terminal has nothing attached to it.

Apologize for the error.
