I'm not sure of the wire placement. I have a black and red wire attached to my old thermostat. Then a black and white coming out of the wall. The new thermostat has attachments labeled G, RC, Rh, Y/O, W/B, Y1. There is a jumper connecting RC and RH. Do I connect the black wire to RH and the white wire to W/B? Any help would be greatly appreciated.
