Here’s a simplified look at common wire functions you might see on a Bosch Heat Pump Wiring Diagram:
| Wire Color/Label | Function |
|---|---|
| R (Red) | 24-volt power (often from the transformer) |
| C (Common) | Continuous 24-volt power (needed for Wi-Fi thermostats and some systems) |
| Y1/Y2 | Compressor stages (Y1 for first stage, Y2 for second stage cooling/heating) |
| W1/W2 | Heating stages (W1 for auxiliary heat, W2 for furnace heat if a dual-fuel system) |
| G | Fan control |
| O/B | Reversing valve (O for cool mode, B for heat mode, or vice versa depending on the model) |
When dealing with any electrical work or troubleshooting on your Bosch heat pump, always refer to the specific Bosch Heat Pump Wiring Diagram that came with your unit. This will ensure you have the most accurate and up-to-date information for your particular model.
