Seriously. At night or low light levels the ATC just functions using the temperature sensor. In daylight it uses both.

HMMmmm I would have preferred a more technical answer involving moonlight sensors in the roof rails (or similar). Still, I suppose your answer will suffice

I think you are all wrong

It is a Toblerone and it has been there so long it has fossilised

Well, in that case mine has melted somewhat. Looks more like an oversized Cadbury's Milk Button.

Or maybe its the remains of a Malteser that has had it's inside honeycomb sucked out by a very tiny straw...

...the posibilities are endless

Thanks for all your replies got a few ideas what it now does or can do, I think! Cheers Kev

It's a miniature version of those automatic weather station buoys out in the ocean that send sunlight sensing, amongst other things, back to the met office by wireless. In our case it sends it to the cabin heating control and makes a correction to stop overheating in the cabin. It saves us having to have a real weather station buoy on the roof with all the problems that would entail. I wonder if other cars have them? (the sunlight sensor, I mean)

Yes, many do. Quite a lot these days have dual sensors, that is for left and right, in the same housing. That way it can tell where the sun is too and compensate, for example if its shining on the passenger but not the driver.

Hi, I am now living with my second 75 Tourer, PX first Y reg at 187000 miles, this one is a bit younger with less miles on the clock. Both have had the same problem,cold air only on the passenger side; my wife thinks I did it on purpose; as if I would! Button test says FC 21 and 22 the 'sun sensor' ( that little black thing on the dash I assume?) Now what do I do? I can't find any info on removal or refiting. Any ideas?

Good grief that's an old thread you've resurrected !!
Sounds like you may have a problem with the thermostat if your not getting any heat when the engines warm.
I'm sure more technical bods will be along in a while.
