    i just wonder what happened to that 4-ish page thread here that was full of talk about hvac<->comp interconnectivity. if it was still available i was gonna link him to it.

    nvm. found it. apparently the forum was set to only sow posts from the last day. look here for more info on computer controlled heat & A/C.

    could you just use a usb servo controller to push the button/flip the switch? you could also use that to control windows and stuff.

    if its all electronic you could probably just get yourself a relay board (maybe more depending on your application) and wire the relays to thwatever switches/buttons youve got. the reason why the servo controller is needed is for the manual knobs and sliders for temperature and vent control.

    it's a '04 vw golf gti with options like heated seats, i found a relay board for the windows, sunroof, hatch, and gas release http://www.dashwerks.com/dw_pvic.php but i'm not sure what has to be done for the temp controls since they're knobs.

    it might appear the if you see knobs that means its all manual but yet in your case heater box and everything else is controlled via servos so you can easily wire it up to the parallel relay
    it can be done

    Am I under the right impression that you got a control modual that will control the manual HVAC Controls? Like The buttons and temp and fan speeds?

    In my car the venting and temperature selection is manually controlled by knobs. I needed to interface stepper motors to those. I use a parallel port controller board for that.

    For user info/keypad input, i am using a Crystalfontz 633.

    to control A/C, Defroster and Fresh/Recirc air, i am using the 3 of the 4 fan controlling outputs of the 633 to drive some logic chips to control the cars fan, and 3 of the GPIO to control relays for A/C, Defroster and Fresh/Recirc buttons.

    The software is being written in C#. I am still working on this but i am very close to being done. Ive been working on it for almost a year now.
