I have been searching for this module for new cooled seats I bought, and came across this item for sale. I have never seen this button before. Does anyone know what it does?
This module does not work for me, but curiousity is killing me
I am not sure but it may? be the same as the Rest feature (right below the AC button in other MBs like so: http://s3.amazonaws.com/photography....9af8d5f785.jpg) in which it uses residual heat to keep the cabin warm in winter or use the residual cold air from the AC to keep the cabin cool in the summer?
However I am second doubting my thoughts because it seems like the button shown has two stages.
I believe you can continue to have heat in the cabin after the engine is turned off. By pressing this button, the coolant will continue to circulate and you can have heat as long as the coolant stays warm.
Why duplicate it and why two settings (two indicator lights)? I mean maybe you guys are right, I initially thought same but those two questions seed doubt. So far no one here, on FB group or on Russian benzworld forum has claimed to have used it lol
Not too sure about why there are two stages/levels but it is on the W223 as well, I guess the icon (Rest vs the logo instead is market dependent) (Image courtesy of another forum member here) https://cimg4.ibsrv.net/gimg/www.mbw...9f49bf557.jpeg
As already mentioned, this would be the Rest function.
Icons vs lettering are market specific. For example, in the US the keyless go engine start button has start/stop on it, but for the Canadian market it has two icons to indicate start/stop engine.
The two Rest stages are not unlike the three stages for heated or ventilated seats. If you turn the seat to highest setting, it will, after a period, reduce itself to middle (two) and the later to low (one). Same with the Rest function. I would find that convenient when walking away from a vehicle and returning to a cold cabin. The higher setting will heat the cabin quicker and the the lower setting would maintain the heat. I'm assuming that the lower setting will also consume less battery by not circulating the pump as fast, thus making the system more power efficient.
On the E class in the mid 2010s, the Rest was a three stage button, just like the heated and ventilated seats.

What did you have in its place in your original panel? Or was it a blank placeholder?

OKay that makes sense. If you have this button then is the rest button on climate control redundant then?

On mine it is the button to disable parktronic. This is kind of why I am trying to figure this out - I find the parktronic button useless, and if this is a cool feature I would consider it. If it is just rest function, then I am not that interested as I rarely use that on the climate control panel

If you have Rest option, you would have the button for Rest. If you don't have the option, then you would be missing the button. It looks like the panel you found is from W164, but not sure if it's for the NA market. I see it on Russian sites from a quick search. Maybe the X164s also had the same panel in other markets. I am not sure.
Do you have Rest on your AC button? That's where mine is (2010 550). The Parktronic button comes in handy when your parking sensors are testing your sanity. I was driving through a path with overgrown high grass (as high as the hood) yesterday and the sensors were going off constantly. Both front and rear. The P button brought much desired serenity to the cabin.
I've only used Rest once and it drained my battery. Mind you it was not the correct battery for the car and I have since replaced it. I don't think Rest is an option to use on a regular basis, for me at least. If I need the car warm, I'd run the motor.
Berween Parktronic and Rest I would rather have the Parktronic button. Just my 2 cents.
Edit: I didn't answer your redundancy question. Yes, the fan with arrows and the Rest button make each other redundant.

Exactly, I have rest on the climate control module. It looks like image below but with picture instead of "rear" on the button for 3rd zone. As you pointed out because of canadian market.
So if the button in question just duplicates this then for sure parktronic switch stays
