 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.

+Le mode sécurité est possible sur tous les types de VTherm . Il survient lorsqu'un des 2 thermomètres qui donne la température de la pièce ou la température extérieure n'a pas envoyé de valeur depuis plus de `security_delay_min` minutes et que le radiateur chauffait à au moins `security_min_on_percent`.

 Comme l'algorithme est basé sur les mesures de température, si elles ne sont plus reçues par le VTherm, il y a un risque de surchauffe et d'incendie. Pour éviter ça, lorsque les conditions rappelées ci-dessus sont détectées, la chauffe est limité au paramètre `security_default_on_percent`. Cette valeur doit donc être raisonnablement faible (10% est une bonne valeur). Elle permet d'éviter un incendie tout en évitant de couper totalement le radiateur (risque de gel).

 ## Why does my Versatile Thermostat go into Safety?

-Safety mode is only possible on VTherm `over_switch` and `over_valve`. It occurs when one of the 2 thermometers which gives the room temperature or the outside temperature has not sent a value for more than `security_delay_min` minutes and the radiator was heating at least `security_min_on_percent`.
+Safety mode is possible on all VTherm's type. It occurs when one of the 2 thermometers which gives the room temperature or the outside temperature has not sent a value for more than `security_delay_min` minutes and the radiator was heating at least `security_min_on_percent`.

 As the algorithm is based on temperature measurements, if they are no longer received by the VTherm, there is a risk of overheating and fire. To avoid this, when the conditions mentioned above are detected, heating is limited to the `security_default_on_percent` parameter. This value must therefore be reasonably low. It helps prevent a fire while avoiding completely cutting off the radiator (risk of freezing).
