This wire connects to your heat pump if applicable. White w heat signal. This could happen if the wires are swapped on both ends or if there s a spice in the wire somewhere that was not matched up to the correct color. This wire may be red without an h attached in some cases. It s important to note that in some cases the color of the wire does not necessarily mean it connects to that came color one the board. Well explained tutorial on wire color codes. When taking into consideration your thermostat wiring colors the orange wire typically connects to the o terminal while the dark blue wire connects to the b terminal. The most essential colors are red green and yellow although you may find up to eight different wires in a heat pump thermostat or as few as five in a more common hot water system. O wire for reversing valves in amana carrier ducane goodman heil janitrol lennox heat pumps may vary for othe rmanufacturers dark blue wire for reversing valves on rheem ruud heat pumps. Therefore here s the color to label diagram for a typical thermostat.
Additionally the common sometimes black should come from the common side of the transformer.
Red r power for the thermostat. However your connections may seem a little different on the thermostat itself. Just take a look at the picture below the diagram. The red wire should always come from the hot side of the 24 volt transformer. The basic heat a c system thermostat typically utilizes only 5 terminals. O wire for reversing valves in amana carrier ducane goodman heil janitrol lennox heat pumps may vary for othe rmanufacturers dark blue wire for reversing valves on rheem ruud heat pumps.
The rc wire connects to the cooling system. Additionally the common sometimes black should come from the common side of the transformer. When taking into consideration your thermostat wiring colors the orange wire typically connects to the o terminal while the dark blue wire connects to the b terminal. This thermostat wire color code will help homeowners understand the anatomy of their thermostat. The rh wire connects to the heating system. This wire may be red without an h attached in some cases. However your connections may seem a little different on the thermostat itself. The red wire is connected to terminals beginning with the letter r which include r rh and rc units depending upon how the thermostat is being used. This terminal provides the connection between electricity supply and system circuitry so it is vital that this wire is connected correctly. Blue or c wires.

O wire for reversing valves in amana carrier ducane goodman heil janitrol lennox heat pumps may vary for othe rmanufacturers dark blue wire for reversing valves on rheem ruud heat pumps. Blue or c wires. The rh wire connects to the heating system. The rc wire connects to the cooling system. We recommend to always work with the labels instead of colors but they do go missing much more frequently than colors of the wires. Here is the industry standard thermostat wire color code used for most systems.
The green wire connects to the fan. The red wire is connected to terminals beginning with the letter r which include r rh and rc units depending upon how the thermostat is being used.
