in THE MAIN WALL
does anybody have any info on the honeywell smart valve?.... the reason why im asking is that the gas valve has a 4 wire plug with a black,white,blue and orange wires. i know the black and white are a constant 24v, and the blue is another 24v circuit.. but i dont understand what the 4th wire[orange] is? it seems like when main gas is energized the smart valve sends 24v back to the circuit board? dont know why ....any explanations?

    On a forced air furnace it tells the fan timer board that ignition was successful. The fan timer then turns on the fan after the set warm up time.
