I installed the honeywell rth230b thermostat in the house for a furnace. I hooked all the yellow wire green wire and white wire up to each of the corresponding holes for each color
I have a red wire and two holes for rc and rh not sure which hole to put the wire and is it supposed to be jumpered between the rc and the rh. I don't that they are jumpered. Can someone tell how to tell if they are or not?
