    How to connect Programmable Thermostat without colored wires?
    The Honeywell I am attempting to install only has 2 Black wires. My old one has 5 wires, two that connect at the top, two that connect at the bottom and a copper one that connects lower at the bottom. I'm not sure where the black wires on the new thermostat needs to be connect, or what I should do with the extra wires connected to the old thermostat. Can anyone help?
