My second Citroen - C1 Flair Puretech

Hi - GiveMeABreak

Please look attachment.
Wiring are the same like in my car Citroen C1.
NO control, timer. Nothing. Only switches.

I can tell you that on the earlier models it can be automatic:

The rear screen demisting-defrosting control (2) only operates when the engine is running.
To start the rear screen demisting function:
Press switch (2)
The warning lamp lights up

The rear screen demisting - defrosting control.

N.B. : The rear screen demisting-defrosting function is switched off automatically to prevent an excessive consumption of current.

N.B. : When the engine is switched off before the end of the rear screen demisting-defrosting, this resumes when the engine is switched on again.

To stop the rear screen demisting-defrosting function:
Press switch (2)
The warning lamp is switched off

On the earlier model circuit, there is the earth the supply and another wire - likely the control wire from the BSI to turn the supply off.

You could though upload to Google Documents and post a link to it. Assuming that you have a Google account, or create one for that purpose.
