heat pump tstat install
 
I'm trying to switch my old trane stat to a new honeywell stat. i think I've got it figured out but i don't know where to put the 't' wire in the new stat. i believe it controls the thermistor. please help.

old stat: new stat:
red-r c-blue
tan-t
orange-o o/b-orange
green-g g-green
yellow-y y-yellow
white-x2 to u e-white
blue-b c-blue
l-open
aux=open

aux needs jumpered to E. Tan is taped off and not used.

why is 't' tape off. it is connected in the condenser outside.

the honeywell thermostat does not use it.

will it effect the heat pump in any way? performance?

does the 't' wire control the thermistor?

T sent a signal to the old t-stat for temp. It is not necessary for the new thermostat. It really doesn't matter what it did. It was only for proprietary thermostats from trane.

the t terminal is only required for that trane tstat. it was used for the heat anticipator. that stat needed the t input. the honeywell does not.
