    Good afternoon,
    I am trying to complete components for bathroom ventilation and would like to use a CS3-1B fan timer. The fan would be 14W and as lighting would be "led" fluorescent lights.
    Below I show the wiring diagram for the installation. Since the resistance load of the controller for the consumer is between 20 - 350W and the fan is 14W, a resistor of min. 2,7 kΩ. I understand that it should be switched in series with the fan? Will this not interfere with the fan? Its performance? If I am thinking something wrong please comment.

    To load the relay output, a resistor should be connected in parallel to the fan. However, I don't think this is necessary. Check that the relay will work well without the resistor.
    Remember that the resistor will heat up, it needs to have an acceptable loss power of at least these 6W and preferably 10W.

    So logically, the resistor should indeed be connected in parallel so it doesn't interfere with the fan, but in some online shop or alle the seller wrote about a series connection....
    I can try to connect it without a resistor to start with.
    Or should I look for some other controller?

    The data sheet (https://www.elektrobock.cz/pl/wylacznik-czasowy-pod-przycisk/p7 ; CS3-1B-instructions) states that the load power is between 5-350W).
    So your 14W load should start without any problem. Good luck :) .
