I also understand a lot of moving around would be done and that I would lose my original control (possibly forever if I needed to hack it up/solder/desolder)...

I know you said FUTURE VERSIONS, but I sure as hell hope the release isnt being delayed because of adding this sort of thing...

These are always very true points to consider

To be able to complete such an install its no lie that you will need to be very competent with a soldering iron and have a good understanding of basic electronics, i.e swicthes and motors

And rest assured AIMEE is not been held back while we implement this feature mainly because its already implemented

its the hardware that is still work in progress hence why im gathering information

Has anyone actually looked at what is actually connected to the AC controls? Just to give you a heads up. Other than fan speed. Many vehicles use vacume lines, valves and cables to control Heat and AC. This is even true for many high end vehicles.

So without knowing preciesly what is under the dashboard, the answers to the guestions asked above could be very misleading.

Then you have other issues like dual zone, single zone, does the car have memmory settings for driver passanger? Does the system control the compressor and heating valves directly or is that processed by HVAC control unit?

Face it guys to make this work on anything other than your own vehicles you will have to have test vehicles at your finger tips from different models, manufacturers and years.

Either that or it will have to be a generic relay control hack that basically engages and disengages a relay bank at the touch of a on screen button. And that is already available. In addition it will still have to be a custom install for about every vehicle.

How do I know this? Because for I worked on Rolls Royce, Jaguar, Mercedes, Rover, and other imports as a professional mechanic for a number of years.

Very imformative post

But this ofcourse is what we have been researching for several months

Mastero has already created a standalone Climate control system using our

software. that is already in production and avaliable to buy

hes proven it to work on many vehicles and has based the design on that

fact

Obviously this isnt for everyone and only the super competent may consider

to undertake this install.

However the system will be super flexable to allow you to do this

accensound you miss the point I think... although there are all those complex types of interactions between HVAC control unit and HVAC compressors, etc, the control units follow some sort of standard.... basically knobs/buttons/sliders, etc...

from what I understsand this project owuld be able to control the control unit, not replace it! so again, it will work on most units I gather...

doing it directly would be basically impossible... tka emy car for instance, the control unit speaks to a AirCon ECU, which only then commands the compressor... the protocol for airconecu->control unit comm is of course proprietary... but emulating a button press on the control unit is very much simple...

correct me if I'm worng Dancehaven, but this is how I think your gonna do it right?

SPOT ON

To a certain extent

To be totally hohnest based on what research we have already conducted

theres not that much to it!

Its a case of measureing and monitoring temp sensors and controlling various

outputs and motors based on the temp readings.

Theres no reason what you couldnt replace the entire system with this unit

**RoyN** · 08-20-2005, 04:18 PM

what I'm saying is that you wont need to interface to complex things like vacuum hoses, etc...

Essentially yes

If people need to be able to drive a motor directly or fit a servo to control a

mechanical slider then the module will also allow this
