How complicated are heating controls in a car? In my p2 N16 everything is electronicly controlled, but this is only by controlling acuators on paddles that direct airflow and control the heater box.

Shot in the dark here, but I'm wondering if a control unit from another car could work? BMW, Seat etc all have seperate modules that control A/C, fans, heater so could the signals being sent (if they were simple controls) by these control the functions in another car, in this case my p2?

As I say, shot in the dark but would be great is anyone has a clue about this sort of stuff.

Thanks :)
 
If you hook up an oscilloscope to the actuators in the almera and to the controllers from another car, you could see how possible it is. If the signal is not too complex you could make a controller which takes the signal from the control unit in another car and outputs a signal compatible with the standard almera. If you wanna delv into it a bit I can borrow my Dad's oscilloscope and come have a look sometime?
 
Come to Guildford meet :) Extention lead + travellodge room + open window + osicllotroythingamajig = win!
 
I would come to the guilford meet, but Poor + Student + Need food + France meet + 300 mile round trip = Not so much win :( lol. Can you hold on until either France or Nuneaton?
 
I don't have a module from another car but we can still test what's coming out of the OE controls, and that will be of some use right?
 
Yeah should be, as I mentioned before you could even make a car pc, and with that info you could design an interface to the computer. Either that or it'll be a step on the way to communicating with another heater control module.
 
Yeah the car pc idea still interests me, but the more than instant boot-up is a big disadvantage :/ I think I'll be going for standalone audio and at the mo just find a way of getting control of the heater/ac functions once my center consol silly gismo thinga has gone... which ever way that may be.

I have however just bought this. Now this looks more complex than the p1 heater controls which otherwise look the same, if not for the windscreen icon (from what I can see it looks like it might be a demist function where if you put the dial round to the windscreen icon, the fan blows @4 and the heater comes on... or more likely the icons are just there to 'help' people who don't know how to demist a windscreen! :lol: Either way it's given me an easy goto backup option of manual controls :)).
 
It might be a tricky alternative, but would it be THAT hard to remove the Ph2 electronic heater actuators and replace it with Ph1 manual ones? Then you could just get a standard Ph1 heater controller and hook it up normally...
 
Oh yeah I've totally got that option on the cards... but if I can keep my little electronic luxuries (I like them sometimes :O) then cool, but if it's hard to do then I'm not that bothered and will be happy going with the manual option.
 
I hope to god there isnt, as it'll mean the controls in my N16 are Renault! I don't think I could live that down anyway. The less french bits the better :D
 
Gone all JDM tyte and bought an R33 JDM digital climate control. Whether I can get it to work or not is another matter! :D

THIS leads me to think it might be possible.

Looks pretty cool too :D
