  • HVAC help with Fusion Brian

    Hi I was looking at another board here for the sole purpose of HVAC control it had software etc but the guy seems to have disappeared.

    So I stumbled upon the Fusionbrain, I currently have a CarPC the Infill T3 running the latest Streetdeck V2.

    The problem I face is the Infill T3 retractable screen covers up my Climate controls in my Subaru Legacy when it is on. So I would like to get the Fusionbrain and integrate my climate controls with it on the CarPC so I can still use them.

    I am however confused as to what to get. My 1999 Legacy has the following climate controls, this is a pic before I installed the Infill T3 CarPC


    Do I need anything further than just the FusionBrain? I have opened up the radio area of the dash a few times, and the climate control connectors are easy to reach, however how would I know what wire does what?

    And also once hooked up to the Fusionbrain am I still able to use the manual controls on the panel?

    To figure out what wire does what, you need to find a wiring guide for your car. Depending on how they set it up, you will need various other things. You will need relays at a minimum. Every car is different, there is no DIY guide.

    All depends on how you wire it.

      Thanks, Also would I need to do any programming, i.e. create a program? I don't know how to program and would rather not. The board that I linked to in original post comes ready to go with software i think, I would like something similar.

        you will have to create your own program and graphical interface

          Not true

          We provide the software free of charge. You will need to do some configuration since it is a custom setup. But the backbone is all done. We also supply generic images to use in a graphic interface. If you want something unique or something that blends in with your frontend skin or something, then you will need to create those graphics.

            I'm not sure of the capabilities of the Fusion Brain to control HVAC. That is why there is a dedicated controller board out there. To get down to temperature and maintain it really requires more than just turning on and off the air con based on a temp sensor. This requires an Integrative approach so that the temperature is converged on by making big steps if a long way a way and then smaller steps as you get closer to the target temperature. Controllers that do this are called PID's. See here:

            http://en.wikipedia.org/wiki/PID_controller

            So does the FusionBrain do PID control?

            Here is a discussion of a DIY PID approach

              The software handles all the logic. Anything is possible with the Fusion Brain.

                Yes, there is free software (which I must say is pretty good) and it has generic images for a graphical interface. But won't you have to create all the logic? Although I don't think it's very hard after looking at a few examples. And there's plenty of support on these forums.

                  Yes, you have to create the steps (logic) but it isn't that difficult. The biggest challenge will probably be in creating the interface (hardware) between the Fusion Brain and your AC unit.

                    too bad that dude disappeared that looked promising.

                      time to re-visit this..

                      I don't want fusion brain to take over and maintain the HVAC, that may come later. All I want is it to push the buttons to turn it on, change options (buttons), adjust temperature, turn on/off A/C or just the heater while letting the car itself control the HVAC

                      So basically just activate buttons or turn the temp dial through signals to the correct wires. Since the physical buttons aren't reachable when my CarPC screen is up.

                      Is this possible and simple to setup without programming? Can the existing software do it just requires some configuration?

                      thanks

                          Hi
                          I have the same heater control and was thinking the same thing.
                          In addition to controlling the buttons with the Fusion brain i was thinking of trying to get the display to work on the Car PC as well. I.e the temprature etc..
                          I have looked at the software that come with fusion brain. I would like it to be integrated to centrafuse so that i can see the heater reading from there.
                          will have to look into it
