I am installing a Honeywell RTH221 Thermostat. I have only 2 wires connected to my old thermostat. I traced them on the furnace. 1 goes to a module that contains a thermocouple. The other goes to a terminal with 2 connections on it, one being a wire that goes straight to my thermostat. What terminals do I connect these two wires to in the new thermostat. Thank you
