My old magic stat thermostat is wired as follows

Red and yellow wire both to R terminal with jumper inplace for rc

Balck and green wire both to W

The directions for the new thermostsat says no 2 wires to the same terminal
Can any one help, I am a little confused...

I have a conventional oil burner heating system.

Thanks

The Rc and Rh get jumpered for homes with AC and only one transformer on the furance. Please clarify the colors coming out of the wall, name each wire.
