I have an Evcon furnace model# DGAH056BBSA and I am wanting to put a Honeywell tstat model# T8034C on it. My problem is that most tstat that I have dealt with have an rc and rh to jumper with, this one doesn't have. I also have 5 tstat wires coming out of furnace: r,y,g,w, and black. What is the black one for? How should this be wired up?

Thanks

Did you make note to see where the black was hooked up to on the old t-stat?

Where is it hooked up onto in the furnace itself?
