Auto heating with AC Off?

I've spent about a year now trying to get to the bottom of this, a few times I've managed to get auto heating mode with AC switched off.

Here is the way to set it up (Kudos to all the members on RZOC who tested my various iterations of this while I was trying to work out the hack).

1. Start car.
2. Dial desired temp and press auto
3. Press AC off and wait a minute.
4. Switch car off, lock up and go away for a while.
5. Go back to car, unlock, start car.
6. Press windscreen max and then press it again.

Once in place this hack will remain persistent on restarts, you can change temp but if you press any other heating buttons it will go back to normal and you'll need to follow above process again if you want auto with AC off.

It's the delay and locking the car that makes it work. Vehicle Car Auto part Speedometer Compact car

Reason to use this hack?

Well I think it perhaps heats up a little quicker and it uses a smidge less power over a trip. but that's just my gut feeling. why not try it yourself and report back.

I did a simple test recently trying out different modes of maximum heating. The outside temperature was around 0 celsius.
While parked I started the Zoe and let it run for three hours.
First hour: heat to max and auto, except that I diverted all the air to the middle dashboard vents.
Second hour: same as first, but with AC off
Third hour: same as second, but with recyling on.

I had a Netatmo outdoor module placed 10 cm away from the vents with air blowing directely at the module to measure temperature during the experiment.

The temperature of the air blowing from the vents quickly reached 30 celius then 45 celius. Temperature remained at 45 celius regardsless of the changes I made (AC off, recycling on).
The consumption however was a different story.
First hour; 2 kw
Second hour: 2 kw
Third hour: 1 kw
