I need to replace a Honeywell T841A1001 thermostat on a heat pump, and of course they do not make this one anymore.

The old thermostat wiring was as follows"

R = Red
O = Orange
G = Green
Y = Yellow
W2 = White with Jumper to X

I believe the W2 white wire is for heat strips that were never installed in my heat pump. If I choose a new thermostat such as the Honeywell TH3110D could I just leave the white wire disconnected and hook the rest up to the proper terminal? I see no reason to pay more for a thermostat with AUX heat when I don't have heat strips.

Please let me know if I am thinking correctly or am a little mixed up.

Thanks,

Mike
