I am trying to replace our current Weathertron THermostat with a Honeywell. We have a heat pump with auxiliary heat and central airconditioning. All the wires matched except the Weathertron had a "T" wire and there is no corresponding connectiion that has a "T" on the Honeywell. I have the "B" wired to "C" per manual instrutions; "G" wire to "G"; "Y" wire to "Y"; "O" to "O/B"; "R" to "R"; "X2" to"E" per manual instructions. I just have no idea where the "T" which is a brown wire needs to go. Thank you, Calvin
