I'm want to install the thermostat on our Electric Furnace.
The wire leading to the furnace is a two wire (BLACK AND WHITE WIRES)
It's heat only. The thermostat has a W and an R on the back of the stat.
The furnace terminal has Y,W,O,C,G,F. The WO has a jumper between them?
The W has a White wire on the top. The O has a red wire on the top. The C
Has a yellow wire and the F has a yellow wire on the top. So for heat only
Where should I connect the black and white wires from the thermostat?

Thanks

Bruce

Which terminals do the two wires from my thermostat connect to on my electric furnace.the terminals are marked ywocgr the jumper wire goes from o to r

I think you mean "R" not are.
If the thermostat has white and black, treat the Black wire as Red.
Without knowing the type of furnace and not having a diagram makes it difficult to give a correct OR safe answer. Is this new installation? Are you just replacing the old thermostat?
