| + | [* black] With mains power disconnected, all wires are cut from the control board and extended though a couple of holes in the top (wooden) work-surface. |
| + | [* black] The mains live is connected to screw terminal 1 and extended to 7 (see circuit diagram in image). The mains neutral is connected to 2 to complete power to the unit. The black wire connects to 8 to complete a switched-live to the pump. There is no switched heater, so no connections to 5 and 6. |
| + | [* black] The thermistor wires are connected to 3 and 4. I could have used the thermistor that came with the STC1000, but to save drilling a hole in the fridge, I used one already in the fridge as it appeared to have a very similar...... |
