 Si votre équipement ne comprend pas le mode Turbo, le mode Forte` sera utilisé en remplacement.
 Une fois l'écart de température redevenu faible, la ventilation se mettra dans un mode "normal" qui dépend de votre équipement à savoir (dans l'ordre) : `Silence (mute)`, `Auto (auto)`, `Faible (low)`. La première valeur qui est possible pour votre équipement sera choisie.

+#### Le démarrage / arrêt automatique
+Cette fonction a été introduite en 6.5.0. Elle permet d'autoriser VTherm a stopper un équipement qui n'a pas besoin d'être allumé et de le redémarrer lorsque les conditions le réclame. Cette fonction est munie de 3 réglages qui permettent d'arrêter / relancer plus ou moins rapidement l'équipement.
+
+Pour l'utiliser, vous devez :
+1. Ajouter la fonction `Avec démmarrage et extinction automatique` dans le menu 'Fonctions',
+2. Paramétrer le niveau de détection dans l'option 'Allumage/extinction automatique' qui s'affiche lorsque la fonction a été activée. Vous choisissez le niveau de détection entre 'Lent', 'Moyen' et 'Rapide'. Les arrêts/relances seront plus nombreux avec le niveau 'Rapide'.
+
+Une fois paramétré, vous aurez maintenant une nouvelle entité de type `switch` qui vous permet d'autoriser ou non l'arrêt/relance automatique sans toucher à la configuration. Cette entité est disponible sur l'appareil VTherm et se nomme `switch.<name>_enable_auto_start_stop`. Cochez la pour autoriser le démarrage et extinction automatique.
+
+L'algorithme de détection est décrit [ici](https://github.com/jmcollin78/versatile_thermostat/issues/585).

 If your equipment does not include Turbo mode, Forte` mode will be used as a replacement.
 Once the temperature difference becomes low again, the ventilation will go into a "normal" mode which depends on your equipment, namely (in order): `Silence (mute)`, `Auto (auto)`, `Low (low)`. The first value that is possible for your equipment will be chosen.

+#### Automatic start/stop
+This function was introduced in 6.5.0. It allows VTherm to stop equipment that does not need to be turned on and to restart it when conditions require it. This function has 3 settings that allow the equipment to be stopped/restarted more or less quickly.
+
+To use it, you must:
+1. Add the `Use the auto start and stop feature` function in the 'Features' menu,
+2. Set the detection level in the `Auto start and stop` option that is displayed when the function has been activated. You choose the detection level between 'Slow', 'Medium' and 'Fast'. The 'Fast' level will result in more shutdowns/restarts.
+
+Once configured, you will now have a new entity of type `switch` that allows you to authorize or not the automatic shutdown/restart without touching the configuration. This entity is available on the VTherm device and is called `switch.<name>_enable_auto_start_stop`. Check it to authorize the automatic startup and shutdown.
+
+The detection algorithm is described [here](https://github.com/jmcollin78/versatile_thermostat/issues/585).
