Room Thermostat – A simple room thermostat that allows the setting of temperature for that room which is connected to the main system to control heating and cooling. If your O or B terminal shares a label with another wire — typically W —identify whether you have a heat pump system or not. A heat pump runs your compressor for both heating and cooling. If you don’t know your system type, place this wire in the W terminal. If you have a heat pump system, put it in the O/B terminal.

Or Red to the thermostat R terminal which is shared with both the heating and cooling. It has an internal jumper built into the sub-base. The red wire is the source hot wire from the transformer.

Since the thermostat also needs power to Rc, I needed to use the jumper from R to Rc. For some reason, my thermostat did not include the factory made jumper , so I just used a short piece of wire (the little U-shaped green wire). Luckily, I had an unused third wire in my bundle, so I attached it to outer F at the furnace to use as a C wire. The red wire is attached to the outer T, and the white to the inner T. The red & white were originally reversed, so I swapped them at the furnace. So, red is in essence tied to the transformer, and carries constant power.
