+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.

+1. Ajouter la fonction `Avec démmarrage et extinction automatique` dans le menu 'Fonctions',

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).

 Self-regulation consists of forcing the equipment to go further by forcing its set temperature regularly. Its consumption can therefore be increased, as well as its wear.
 
-#### Self-regulation in Expert mode
-
-In **Expert** mode you can finely adjust the auto-regulation parameters to achieve your objectives and optimize as best as possible. The algorithm calculates the difference between the setpoint and the actual temperature of the room. This discrepancy is called error.
-The adjustable parameters are as follows:
-1. `kp`: the factor applied to the raw error,
-2. `ki`: the factor applied to the accumulation of errors,
-3. `k_ext`: the factor applied to the difference between the interior temperature and the exterior temperature,
-4. `offset_max`: the maximum correction (offset) that the regulation can apply,
-5. `stabilization_threshold`: a stabilization threshold which, when reached by the error, resets the accumulation of errors to 0,
-6. `accumulated_error_threshold`: the maximum for error accumulation.
-
-For tuning, these observations must be taken into account:
-1. `kp * error` will give the offset linked to the raw error. This offset is directly proportional to the error and will be 0 when the target is reached,
-2. the accumulation of the error makes it possible to correct the stabilization of the curve while there remains an error. The error accumulates and the offset therefore gradually increases which should eventually stabilize at the target temperature. For this fundamental parameter to have an effect it must not be too small. An average value is 30
-3. `ki * accumulated_error_threshold` will give the maximum offset linked to the accumulation of the error,
-4. `k_ext` allows a correction to be applied immediately (without waiting for errors to accumulate) when the outside temperature is very different from the target temperature. If the stabilization is done too high when the temperature differences are significant, it is because this parameter is too high. It should be possible to cancel completely to let the first 2 offsets take place

 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.

+```

+         stabilization_threshold: 0.1
+         accumulated_error_threshold: 50
+```
+and of course, configure the VTherm's self-regulation mode in **Expert** mode. All VTherms in Expert mode will use these same settings.
+
+For the changes to be taken into account, you must either **completely restart Home Assistant** or just the **Versatile Thermostat integration** (Dev tools / Yaml / reloading the configuration / Versatile Thermostat).
+
+
+### On Time Clamping (max_on_percent)
+
+
+The calculated on time percent can be limited to a maximum percentage of the cycle duration. This setting has to be made in expert mode and will be used for all Versatile Thermostats. 
+
+```
+versatile_thermostat:
+    max_on_percent: 0.8
+```
+
+The example above limits the maximum ON time to 80% (0.8) of the cycle length. If the cycle length is for example 600 seconds (10min), the maximum ON time will be limited to 480 seconds (8min). The remaining 120 seconds of the cycle will always remain in the OFF state. 
+
+There are three debug attributes of interest regarding this feature:
+
+* `max_on_percent` # clamping setting as configured in expert mode
+* `calculated_on_percent` # calculated on percent without clamping applied
+* `on_percent` # used on percent with clamping applied

 ## 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).
