LR 69071 was wired the following way. G=Green, R=Red, Y=Yellow, O=Orange, X=Blue, and W2 and E= White. Please let me know how the above wires should be connected to the new TH 4210D honeywell thermostat. Thanks in advance.

What letters do you have on the new stat?

what letters do you have on the new stat?

E, Aux, Y, G, O, L, R, B, and C

You have a heatpump system? I don't work with heatpumps much. Sorry I will be of no help here, hope one of the other pros here can help.

All the same w2 is aux, and blue will be L

Do you have any extra wires there? That can be used?

I only have the six wires. I will try it and let you know how it comes out. Thanks for your help.

No problem, with only 6 wires you will not have a common. This is fine, but you will be changing the batteries a good bit in the t-stat.

Thanks so much for your help. I really appreciate it.

Does it work? Gald I could help

So far so good.

Great!!
