Thanks for your Time and Response... my "T" stat (Robetshaw 9610), my unit (York natural gas furnace/AC Mod. # P2MPD12ND6401A), my control board (Emerson 035-21366-001-B-0208). My original qestion... how to wire "T" stat wires to board terminals?

I thought it was a maple chase?

York has nothing close to that Model number.
Emerson White Rodgers has no number close to that number you posted

The Robert Shaw thermostat will only work on one heat and one cool systems. It cannot be used in systems labeled Y2 ETC because that signals the second stage cool circuit and the 9610 is only one stage not two.

If this is a furnace only then RH/RC=RED and w=WHITE will be the two connections

Here is the wiring diagram.
