What Are the Essential Wiring Components for Heat Pump Systems?
Standard Wire Connections Overview
| Wire Color | Terminal | Function |
|---|---|---|
| Red (R) | Rc/Rh | Power Supply |
| Blue/Black (C) | C | Common Wire |
| Yellow (Y1/Y2) | Y1/Y2 | Compressor Stages |
| Green (G) | G | Fan Control |
| White (W1/W2) | W1/W2 | Auxiliary Heat |
| Orange/Black (O/B) | O/B | Reversing Valve |
