Looks perfect Paul,

Just need a version that controls the old stuff

Champagne

Thanks,

the way Porsche designed this system, there is no easy way to defeat the dash vents. They are always on and so that particular icon will remain on. Except for maybe the defrost, but I'm not sure about that one.
But you can add another mode with the rotary, so if you want floor and dash, simply select floor and both icons will light up while air will be distributed in both locations.

Hans is working at coding the speeds and the temps. The LED do represent a logical progression for both functions, but not necessarely a set point.
But one will eventually learn that the 7th LED is perfect for the way he/she like his fan and one light pass mid point is where the temp should be.


That should fit the bill quite nicely then

Thanks

Paul

Nice job , It just seems a little busy

I like the icons on the *****. Perhaps the less LED's around the **** would less busy.

In general I am fine with the appearance. It looks great overall.

matt928

OMG that looks really awesome. So bad that former 928 designers can't see that!
Awesome!

Leon Speed

Looks nice, I just don't get the triangles/arrow heads under the **** symbols.

Champagne

Those are to highlight the "push" function and differentiate those icons from the others.

Thanks Paul for posting the renderings.

Since I am responsible for the inner-workings, I will comment on some of the functionality. The blower is theoretically capable of a near indefinite number of steps, almost a complete level of analog control. I think technically, I can have up to around 255 steps. I think we can all agree that is too many. It will also increase the amount of time to develop. The blower motor doesnt respond linearly to control, so I need to physically measure fan speed at various frequency/duration settings to try and map a linear curve. I want to give a lot of control, but too many steps will require several rotations to get the fan to respond. The rotary encoders I am using are an optical type vs the less expensive mechanical variety. These give a more reliable electrical communication to the controller, and also last much longer. The encoder I am using is rated at 2-million revolutions, and 3-million button presses before failure. Standard mechanical encoders are rated around 30,000 operations. Most optical encoders are expensive, but there are a couple deals out there. So, we are slighltly limited to what encoders we can "afford" to use. We are kind of forced into using a device with 16 detents per revolution. So with 12 steps on the fan, that means that twisting the **** will roughly follow the LED array as you twist. I could increase the ammount of blower positions to 24, 48.... etc, but it woudl requre that many more complete twists of the ****.

I would be flexible on receiving input on how many steps user would like.

On to the LEDs. The LED in the array will only be lit when then are selected. In Pauls rendering, they are just shown so you can see the positions. The secondary "push" function icons will always be lit, and will shift color to confirm status. I think the current scheme is white when off, amber when selected - but that may change to something like constant amber and red selected.... still playing around with LED options.

Paul is correct in saying that there is no real way to defeat the center vent through the climate control. Porsche did not include a dedicated flap for this. You can manually close the vent, but short of that, the center vent is always engaged under normal operations. It is out of the scope of this project to fabricate additional flap dampeners... etc, as we want this to be an easy plug-and-play installation, no permanent mods required.

The rear AC function is a very simple integration. I am still working on a way to add this feature without modifying any existing wiring. In the end, it may require a splice, or removing a pin from the factory harness. Currently, the function included in this controller will allow the user to select the rear AC to engage (or not engage) whenever the temperature is set to MAX-COOL. If the function is enabled, and if the temp is set at MAX-COOL, then the rear AC will activate at its coldest setting, and highest fanspeed. Pressing the rear-ac function when in MAX-COOL will toggle the rear AC on/off, so it is selectable in or out of mode. In a poll to many users around the country, I found that people only use the rear-AC to help rapidly cool the cabin, and then use the front climate to maintain temperature.

The stock rear controls will not be eliminated, they can be moved to a more discrete location, and still used as stock to control the rear. The rear AC system is more challenging that you may expect, as it is a "dumb" device, with no internal temperature regulation. It may be possible to completely incorporate rear AC control into the future OLED version of the controller, but it will be at a significant cost option. It will require the use of an additional fanspeed control module and another potentiometer replacement module. This will be a late addition, and we will likely provide a relocation harness to move the ***** to the parking brake shroud location or the glove-box long before offering an integrated option.

I hope to have a test frame for this layout CNCed tomorrow night, and send down to Paul for the first finished cover. I think we are still on track for a SITM working model. All the carputer functions are ready, and I think i can start finalizing the boards for this revised version of the climate.

Thanks
Hans

Freaken delicious! I can hardly wait. My ***** are broken and I have no fibre optics working. This is going to look great on my car.

S4ordie

You Aryan might be on to something here. Sometimes less is more. IS it really necessary to have directional arrows on the *****? I think everybody almost instinctively twists a dial/**** in a clockwise direction. The movement of the lighted LED's will be an obvious clue as to whether your are increasing temp or fan speed or vice versa.

I think a single Fan icon with no directional arrows and perhaps a white icon of a thermometer with no directional arrows would simplify the appearance. Not a criticism of the what is currently presented, I like it, just another bit of input.

Champagne

These icons were designed so they would remain logical wherever the position of the *****. A thermometer would end up upside down most of the time.

It might be important to reiterate that we are designing these things for ease of production and affordability, but we do still have all the latitude necessary to customise each one. I would not have time to re-design a set of icons, but if someone wanted blank ***** with only the texture and no icons, I could certainly accommodate.

This is fantastic work Hans and Paul!

I'm with Paul on the switches, you also get people not so familiar with the 928’s climate control operation and the icons will make it easier to understand and operate.

Our current blower gives us four speeds; I would think eight would be enough.

When I use the rear air it is on high to cool the car down or compensate for a bad vacuum actuator or heater control valve!

Keep up the good work!

Alan

current is 5 speeds - 0 is in fact a speed - though you'd think not...

Keep up the work. I really hope it become a main upgrade for any 928 owner. Buy a 928, upgrade the center stack. That's how it should be. The way you are both going about it is so wonderful and modern, its really a no-brainer on a nice car.

Leon Speed

Isn't fun to pitch ideas on Rennlist

Keep up the good work! It' a great project.
