    If it will work with only 2 wires, connect one to the RH, and the other to the W. It might be best if you checked to see which one connected to the R terminal at the furnace or directly to the transformer and made it the one connected to RH. See

    It may need batteries for power.

    OK the red wire goes to R. If you have A/C, but only one transformer, jumper R to RC.

    I don't have a/c its just a oil burner, so are you saying that I should connect the Green(ground wire) to C and the brown(hot wire) to R, then should I remove the jumper that connects Rc to R?

    Just connect one wire to R it doesn't matter if jumper is there for R-Rc or not. The other wire goes to W.
