Decken Ventilator
Features
- Up to 120W ceiling fans
- 6 speed steps + off
- Completely silent
Description
The speed is controlled by switching between the different capacitors. In essence its the 4fach Binärausgang 230V with capacitors connected on the output, so you can use the 4fach Binärausgang 230V software to control the ceiling fan controller.
You can call a step by calling a scene what has the corresponding capacitors for the desired speed.
| Speed | Relais | Capacity |
|---|---|---|
| 0 | all off | |
| 1 | relay 4 | 1,5µF |
| 2 | relay 3 | 2µF |
| 3 | relay 2 | 3µF |
| 4 | relay 2 + 4 | 3µF + 1.5µF = 4.5µF |
| 5 | relay 2 + 3 + 4 | 3µF + 2µF + 1.5µF = 6.5µF |
| 6 | relay 1 | maximum speed (direct connected) |
The lower the capacitor's value, the slower the fan speed. You can change the capacitors values and steps for different speeds. I find these values perfect for my Asana fan.
Here is an image with the connected controller board:
You need to use a 10 pole ribbon cable instead of the usual 20 pole ribbon cable. Also, because of the size of the capacitors it is necessary to mount a few objects on the controller PCB on the other side of the PCB so that the housing can close.
