EBB SB2209 Heater not working?

I managed to configure everything using the C2U adapter.
Everything works except the heater.
It does not give any signs of life. I have two different hotels with different heaters, so I can for sure say that it is not the faulty heater.
I just replaced the port in my config for all other sensors, so I did the same thing for the heater.
As I said, all other sensors, extruders, and end-stops are working only it does not want to start heating.

```

Start with the extruder configuration shown in the issue, especially the heater_pin and sensor_pin mappings, and compare them with the working sensor, extruder, and end-stop connections. Reproduce the problem with the two heaters described and determine why the heater gives no response; done means heating works without disrupting the other sensors.
