Ventilate mode

[andyinluton]

but the factory default is to ventilate, and you need to turn on ignition to change it - that's dumb, as the whole mode is a nonsense

No its not, the default is to what you last set it at.

 

[kocotte]

No its not, the default is to what you last set it at.

The factory default is what factory sets, and this is ventilate. Probably also this is where it will go after a major reset of the system.

This Thread was helpful. Currently near gorge du Verdon and tres hot. Ventilate mode is helping, shame it doesn’t work for the rear (tri-zone) area as that’s where my two sweaty kids are

Says in manual ventilate can be used to defrost front windscreen ??
Can ventilate be set to hot or cold ?

Is it efficient at doing this , has anyone tried it ?
If so how long does take to clear front screen ?

Are you sure thats what it says? Ventilate uses outside ambient air, that isn't going to defrost anything, just use the heater.

It does not say ventilate can be used to defrost the window. It says the auxiliary heater can in combination with the “ventilation system”. And not or. That’s not the same as ventilate mode.

 

[Little owl1963]

Am I right saying ventilate only blows on windscreen vents bottom screen an cab face vents so must mean can defrost screen ??

Auxillary heater only blows out B Pillar only to heat living area only so impossible defrost screen .

So what does clear ice as says in manual actually refer to ??
Auxillary or ventilate ?

 

[Little owl1963]

Says top right will clear ice , snow , can anyone confirm , what heater is it referring too ? Diseal night heater, auxillary air or ventilate ?

 

[dspuk]

Auxiliary means additional or supplemental.

Heater gives off heat.

Auxillary heater is the auxillary heater on the van that is extra to the vans transporter heater system.

It's auxiliary.

In your terms, it is the "diesel night heater".

The auxiliary heater has two modes. Heat continuously. It heats continuously to the temperature set until switched off.

The second mode is heat immediately, which heats for 90 minutes (or as setting) and you can use from the control panel or the key fob.

This latter mode is the one that is good for hearting the inside and defrost windows. Eventually. Click the button an hour before you leave.

Ventilate just ventilates air. Think of it as air conditioning if the inside of the van gets stuffy.

Unless it is very hot outside ventilate will not pull in or create hot air. If it is very hot, you won't have ice on the windows. Ventilate does not use the auxiliary heater but the normal fans and air vents.

The ventilation system will defrost windows if it is on and your engine is on.

Steve explains it here:

Auxilary heater question - settings v levels (T6.1)

Not had our T6.1 long, finding the auxiliary heater hard to work out. Went away at the weekend for one night, so used the heater. Kept us warm (yet to get use to the noise of it!) but not really sure how I set it up !! Heat continuously has level settings, how do the settings work? If we go to...

And Andy here:

Ventilate mode

Hello :) Our T6.1 ocean has two modes for the heating, heating and ventilate mode. If I run the van on ventilate does this drain the car battery or it works from the camper (dual leisure batteries)? I ask as we are currently on a site and it’s 11pm... still 26c :/ Also note we are on...

Thanks understand it now .
But can't really see the point of the ventilate mode at all
Has no purpose if its humid inside van. An you ventilate , all will do is put hot air into van .
Likewise if cold inside van. All will do is put more cold air in van .

So what do member s used ventilate for
Does anyone actually use it

I use it when I’m leaving the dog in the van.
Obviously needs to be a reasonable ambient temperature and no chance of the sun cooking the hound (blinds can help, also hides the canine), but if I HAVE to leave her, I stick ventilate mode on. More effective and secure than cracking a window I think.

Says Auxillary coolant heater to warm front end of van , I have starred and underlined in black .
It does state will clear ice an snow .still
Confused what is this AUXILLARY COOLANT HEATER ?

Clearly states front interior an windscreen only. Says Auxillary or extra heater so can't be the normal engine coolant heater ?

Ok, after hitting the resurrected thread I said I would update here. Did a bit of reading and thanks to old posts by forum old hands like Loz, WG and Andy, as well as some T6 forums, it's actually simple.

The manual is right, in context. Out of context it feels like you have control over the coolant heater. Unless you flash it and fit the remote, or have the remote control mentioned above, you don't. Consensus is to retro is a bad idea as it drains the starter too much.

There is mention in the manual for a aux coolant heater (parking heater) remote. I never got one nor was it an option and I ticked every box. So my assumption, please correct, is for the MY21 it was not a thing.

I've also finally checked my Ocean, I have both too. The stickers are on the driver door. In my manual they are both std on a Surf and Ocean, 3.5K extra for a Beach (for both).

Some have put it better than me, but I'll paraphrase them here. Note - both heaters are diesel heaters.

Auxiliary Air Heater. Made by Eberspracher. The heater we all know and love. It is actually called the Airtronic M2 and quite a common unit for diesel drip heaters on vans and boats. It's the semi-confusing Heat Immediately/Continuously one with a remote button for your keys. This is great for keeping warm on a night and to heat the cabin via the air heater. It's therefore good for defrosting the van, just hit the remote 30 - 60 mins before you need to drive off.

Auxiliary Coolant Heater. Made by Webasto. I'll call this a "passive" heater as I believe most, if not all of us, has no real control over it. It's called the Thermo Top Evo. It is also widely used to quickly heat cabins in cold temperatures. I'll call it passive here because it looks like VW have installed it as a heat the cabin up quicker option that needs the engine on and temp lower than 5 degrees. You can install it on cars as an active heater - so you can switch it on and it will preheat the interior of the car. Slide 16 on here explains how it works well.

https://www.webasto-comfort.com/fileadmin/webasto__media/webasto-comfort.com/INT/Documents/car-parking-heater-flyer.pdf

Basically, as far as I can tell, when we get in AND start the engine, if it is >5 degrees this heater kicks in and provides warm air to the cabin very quickly as well as pre warming the engine, helping emissions and economy. That seems to be it. Unless you have a control I was not able to get. Maybe newer/older Calis than mine, or just Transporters.

This far down I can't remember the resurrection posters actual question, or what they are trying to do, but these are the two heaters and how I can work them out.

If you are in the van and sleeping etc. The Air Heater is your friend. If you are starting it on a cold day and wonder why the air is hot much faster than your normal car, allowing the cabin and windows to defrost faster. The Coolant Heater is your friend.

Happy for any and all corrections.

Good explanation .
Yes I have ventilate on top control panel ,also hand held remote.
Proof of pudding is to field test it see what works .
Next time in van later this week will put to test .
Be good if this Ventillation / Coolant heater is actually efficient and quick at defrosting windscreen .

 

[Little owl1963]

So is the Webasto coolant heater.
Actually the ventilate option on top control panel

You appear to be getting confused.
You have no control over your coolant heater, it runs automatically when you start the engine and its less than 5 degrees outside & helps your engine warm up quicker hence the comments about defrosting the windscreen quicker.

If you want to defrost your windscreen before you start the engine you need to use your remote to start the parking heater in heating, not ventilate, mode about 15 mins before you want to use the van. Then when you go and open your van you will find its already warmed up & any ice on the windscreen will be melting.

 

[Little owl1963]

Andy are you saying coolant heater that works below 5 degrees.
Is totally seperate from the Ventilate option on control panel ?
Manual says coolant heater is the ventilate

Ventilation option does not use any sort of heater. - you are not reading the manual properly, after "ventilate ( ventilate the vehicle interior )...... it doesn't mention any sort of heater.

Ventilate mode is sucking outside air into the cabin through the 4 face level vents in the dashboard using the dashboard fans whilst the vehicle is parked.

You turn it on & off using the overhead controls or if the overhead controls last setting was ventilate mode, using the remote control.

 

[Little owl1963]

What model volkswagen do you have Andy.

Read bottom part operating mode of Auxillary heater .

I have pencilled 3 x options .

1. Vehicle interior and windscreen . AUXILLARY COOLANT HEATER .
2. VEHICLE Interior . AUXILLARY AIR HEATER.
3. VENTILATE . States clearly the vehicle interior IS NOT COOLED .

Now 3 heater options above .

How many those heaters does cali T6.1 Have.

Does cali have both Auxillary coolant heater , and this is important issue .
Ventilate by manual , is a totally seperate heater from coolant heater .

Think some on this thread classing it same heater , in manual states 3 seperate heaters .

So states in manual at top , I quote .

It is able to clear snow ice. Is powered by engine 12 volt battery , ignition must be on .
Vehicle interior and windscreen uses auxillary coolant heater.
THIS IS NOT VENTILATE MODE .

Exactly the same model as yours.

Where does it say option 3 is a heater? ventilate isn't a heater, nowhere does it say anything about ventilate heating....

 

[Little owl1963]

In my above post #45
3 options same as says in manual
3 rd option is ventilate.

No mention supplementry heater in manual, but under vehicle settings within radio,
There option to TICK BOX .
Is yours ticked ?

 

[Little owl1963]

Yes ventilate just runs fan .

But think auxillaty coolant heater blows hot air towards the windscreen .
Engine has be running , think uses diseal out fuel tank .
It's a specific special heater to volkswagen .
It's diseal heater

People have been telling you about this since day 1.

 

[Little owl1963]

So auxillary coolant heater if blows at windscreen below 7 degrees will clear ice / snow as says in manual ?
