I have identified wires G, O, Y, W and B on both my old thermostat and the
LUX TX9000, which I'm attempting to install.
However, on my old thermostat, there are two additional wires, a R (red) and
a T (tan). On the TX9000, I have a RH and a RC. What I need to know is how
the R & T hook up to the RH and RC.
Thanks for your help.
