Connect to a Fan controller


Tufve

Question

Hi!

It's a 12v system and I would love to control this with Z-Wave.

W1 sets fan speed down, and W2 sets fan speed up.

I attached a connection idea below but haven't tried it yet.

I burned one Fibaro RGBW already when connecting +12v to 12vDC and -12v to GND.. stupid I guess:-D

 

EDIT: The fan controller alternate 1 pair of fans direction every 60s to change airflow.

Probably why its +12v and -12v?

 

Can I somehow switch W1 and W2?

Disregard my line connections. They are probably soo wrong

Connecting +12 V to 12 V DC and minus to GND is correct to provide the RGBW drive voltage. Perhaps it was another faulty cable that caused the accident.

Are you really sure that the black cable to the switch is minus (GND), I don't think so.

 

GND on the RGBW unit should be connected to the incoming terminal on the LUNOS (where you connected 12V DC).

Are the switch buttons resilient (push buttons)? If they are not, you can get an unwanted result if both the breaker and the RGBW unit are trying to cooperate.

 

The output of RGBW takes you from two of the four outputs R, G, B or W. The RGBW must also be configured as Output Normal dimmer (not RGBW).

But what is the purpose of connecting the switch to IN1 and IN2?

  • Hi RH

    Appreciate your reply.

    Just disregard the above connection.

    My first attempt was to only connect:

    +12v to 12vdc

    -12v to GND

    Thats it.. just wanted to see if the Home Assistant (Razberry 2) node would find the RGBW unit.
    ..a smell was felt and the housing was melted.

    You say this was a correct setup?

     

    My plan was to connect as picture attached below but I am confused.. 

    Set it up as a IN/OUT 

     

    Push buttons switch by springload.
    Push W2 will send ON signal to activate more fan speed

    Push W1 will decrease fan speed
    Hold W2 for 5s gives ventilation mode

    EDIT: the Red/Blue/Purple are to FAN

    So I should switch +12v to be GND and -12v to be 12vDC?
