Afin de réduire la charge du cycle de service, vous pouvez par ex. regroupez les thermostats avec des procédures spécifiques à Homematic (par exemple en utilisant un thermostat mural) et laissez Versatile Thermostat contrôler uniquement le thermostat mural directement.

 Le quatrième param§tre (``security_default_on_percent``) est la valeur de ``on_percent`` qui sera utilisée lorsque le thermostat passe en mode ``security``. Si vous mettez ``0`` alors le thermostat sera coupé lorsqu'il passe en mode ``security``, mettre 0,2% par exemple permet de garder un peu de chauffage (20% dans ce cas), même en mode ``security``. Ca évite de retrouver son logement totalement gelé lors d'une panne de thermomètre.

+Depuis la version 5.3 il est possible de désactiver la mise en sécurité suite à une absence de données du thermomètre extérieure. En effet, celui-ci ayant la plupart du temps un impact faible sur la régulation (dépendant de votre paramètrage), il est possible qu'il soit absent sans mettre en danger le logement. Pour cela, il faut ajouter les lignes suivantes dans votre `configuration.yaml` :
+```
+versatile_thermostat:
+...
+    safety_mode:
+        check_outdoor_sensor: false
+```
+Par défaut, le thermomètre extérieur peut déclencher une mise en sécurité si il n'envoit plus de valeur.

+## Le contrôle centralisé
+Depuis la release 5.2, si vous avez défini une configuration centralisée, vous avez une nouvelle entité nommée `select.central_mode` qui permet de piloter tous les VTherms avec une seule action. Pour qu'un VTherm soit contrôlable de façon centralisée, il faut que son attribut de configuration nommé `use_central_mode` soit vrai.
+
+Cette entité se présente sous la forme d'une liste de choix qui contient les choix suivants :
+1. `Auto` : le mode 'normal' dans lequel chaque VTherm se comporte comme dans les versions précédentes,
+2. `Stooped` : tous les VTherms sont mis à l'arrêt (`hvac_off`),
+3. `Heat only` : tous les VTherms sont mis en mode chauffage lorsque ce mode est supporté par le VTherm, sinon il est stoppé,
+3. `Cool only` : tous les VTherms sont mis en mode climatisation lorsque ce mode est supporté par le VTherm, sinon il est stoppé,
+4. `Frost protection` : tous les VTherms sont mis en preset hors-gel lorsque ce preset est supporté par le VTherm, sinon il est stoppé.
+
+Il est donc possible de contrôler tous les VTherms (que ceux que l'on désigne explicitement) avec un seul contrôle.
+Exemple de rendu :
+
+![central_mode](/images/central_mode.png?raw=true)
+
+## Le contrôle d'une chaudière centrale
+Depuis la release 5.3, vous avez la possibilité de contrôler une chaudière centralisée. A partir du moment où il est possible de déclencher ou stopper cette chaudière depuis Home Assistant, alors Versatile Thermostat va pouvoir la commander directement.
+
+Le principe mis en place est globalement le suivant :
+1. une nouvelle entité de type `binary_sensor` et nommée par défaut `binary_sensor.central_boiler` est ajoutée,
+2. dans la configuration des VTherms vous indiquez si le VTherm doit contrôler la chaudière. En effet, dans une installation hétérogène, certains VTherm doivent commander la chaudière et d'autres non. Vous devez donc indiquer dans chaque configuration de VTherm si il contrôle la chaudière ou pas,
+3. le `binary_sensor.central_boiler` écoute les changements d'états des équipements des VTherm marqués comme contrôlant la chaudière,
+4. dès que le nombre d'équipements pilotés par le VTherm demandant du chauffage (ie son `hvac_action` passe à `Heating`) dépasse un seuil paramétrable, alors le `binary_sensor.central_boiler` passe à `on` et **si un service d'activation a été configuré, alors ce service est appelé**,
+5. si le nombre d'équipements nécessitant du chauffage repasse en dessous du seuil, alors le `binary_sensor.central_boiler` passe à `off` et si **un service de désactivation a été configuré, alors ce service est appelé**,
+6. vous avez accès à deux entités :
+   - une de type `number` nommé par défaut `number.boiler_activation_threshold`, donne le seuil de déclenchement. Ce seuil est en nombre d'équipements (radiateurs) qui demande du chauffage.
+   - une de type `sensor` nommé par défaut `sensor.nb_device_active_for_boiler`, donne le nombre d'équipements qui demande du chauffage. Par exemple, un VTherm ayant 4 vannes dont 3 demandes du chauffage fera passé ce capteur à 3. Seuls les équipements des VTherms qui sont marqués pour contrôler la chaudière centrale sont comptabilisés.
+
+Vous avez donc en permanence, les informations qui permettent de piloter et régler le déclenchement de la chaudière.
+
+Toutes ces entités sont rattachés au service de configuration centrale :
+![Les entités pilotant la chaudière](/images/entitites-central-boiler.png?raw=true)
+
+### Configuration
+Pour configurer cette fonction, vous devez avoir une configuration centralisée (cf. [Configuration](#configuration)) et cochez la case 'Ajouter une chuadière centrale' :
+
+![Ajout d'une chaudière centrale](/images/config-central-boiler-1.png?raw=true)
+
+Sur la page suivante vous pouvez donner la configuration des services à appeler lors de l'allumage / extinction de la chaudière :
+
+![Ajout d'une chaudière centrale](/images/config-central-boiler-2.png?raw=true)
+
+Les services se configurent comme indiqués dans la page :
+1. le format général est `entity_id/service_id[/attribut:valeur]` (où `/attribut:valeur` est facultatif),
+2. `entity_id` est le nom de l'entité qui commande la chaudière sous la forme `domain.entity_name`. Par exemple: `switch.chaudiere` pour les chaudière commandée par un switch ou `climate.chaudière` pour une chaudière commandée par un thermostat ou tout autre entité qui permet le contrôle de la chaudière (il n'y a pas de limitation).  On peut aussi commuter des entrées (`helpers`) comme des `input_boolean` ou `input_number`.
+3. `service_id` est le nom du service à appeler sous la forme `domain.service_name`. Par exemple: `switch.turn_on`, `switch.turn_off`, `climate.set_temperature`, `climate.set_hvac_mode` sont des exemples valides.
+4. pour certain service vous aurez besoin d'un paramètre. Cela peut être le 'Mode CVC' `climate.set_hvac_mode` ou la température cible pour `climate.set_temperature`. Ce paramètre doit être configuré sous la forme `attribut:valeur` en fin de chaine.
+
+Exemples (à ajuster à votre cas) :
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:heat` : pour allumer le thermostat de la chaudière en mode chauffage,
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:off` : pour stopper le thermostat de la chaudière,
+- `switch.pompe_chaudiere/switch.turn_on` : pour allumer le swicth qui alimente la pompe de la chaudière,
+- `switch.pompe_chaudiere/switch.turn_off` : pour allumer le swicth qui alimente la pompe de la chaudière,
+- ...
+
+### Comment trouver le bon service ?
+Pour trouver le services a utiliser, le mieux est d'aller dans "Outils de développement / Services", chercher le service a appelé, l'entité à commander et l'éventuel paramètre à donner.
+Cliquez sur 'Appeler le service'. Si votre chaudière s'allume vous avez la bonne configuration. Passez alors en mode Yaml et recopiez les paramètres.
+
+Exemple:
+
+Sous "Outils de développement / Service" :
+
+![Configuration du service](/images/dev-tools-turnon-boiler-1.png?raw=true)
+
+En mode yaml :
+
+![Configuration du service](/images/dev-tools-turnon-boiler-2.png?raw=true)
+
+Le service à configurer est alors le suivant: `climate.empty_thermostast/climate.set_hvac_mode/hvac_mode:heat` (notez la suppression du blanc dans `hvac_mode:heat`)
+
+Faite alors de même pour le service d'extinction et vous êtes parés.
+
+### Les évènements
+
+A chaque allumage ou extinction réussie de la chaudière un évènement est envoyé par Versatile Thermostat. Il peut avantageusement être capté par une automatisation, par exemple pour notifier un changement.
+Les évènements ressemblent à ça :
+
+Un évènement d'allumage :
+```
+event_type: versatile_thermostat_central_boiler_event
+data:
+  central_boiler: true
+  entity_id: binary_sensor.central_boiler
+  name: Central boiler

+  id: 01HM3VZRJP3WYYWPNSDAFARW1T
+  parent_id: null
+  user_id: null
+```
+
+Un évènement d'extinction :
+```

+### Avertissement
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+> Le contrôle par du logiciel ou du matériel de type domotique d'une chaudière centrale peut induire des risques pour son bon fonctionnement. Assurez-vous avant d'utiliser ces fonctions, que votre chaudière possède bien des fonctions de sécurité et que celles-ci fonctionnent. Allumer une chaudière si tous les robinets sont fermés peut générer de la sur-pression par exemple.

 En mode `over_switch` si plusieurs radiateurs sont configurés pour un même VTherm, l'alllumage va se faire de façon séquentiel pour lisser au plus possible les pics de consommation.
 Cela est tout à fait normal et voulu. C'est décrit ici : [Pour un thermostat de type ```thermostat_over_switch```](#pour-un-thermostat-de-type-thermostat_over_switch)

+## Le radiateur chauffe alors que la température de consigne est dépassée ou ne chauffe pas alors que la température de la pièce est bien en-dessous de la consigne
+
+### Type `over_switch` ou `over_valve`
+Avec un VTherm de type `over_switch` ou `over_valve`, ce défaut montre juste que les paramètres de l'algorithme TPI sont mal réglés. Voir [Algorithme TPI](#algorithme-tpi) pour optimiser les réglages.
+
+### Type `over_climate`
+Avec un VTherm de type `over_climate`, la régulation est faite par le `climate` sous-jacent directement et VTherm se contente de lui transmettre les consignes. Donc si le radiateur chauffe alors que la température de consigne est dépassée, c'est certainement que sa mesure de température interne est biaisée. Ca arrive très souvent avec les TRV et les clims réversibles qui ont un capteur de température interne, soit trop près de l'élément de chauffe (donc trop froid l'hiver).
+
+Exemple de discussion autour de ces sujets: [#348](https://github.com/jmcollin78/versatile_thermostat/issues/348), [#316](https://github.com/jmcollin78/versatile_thermostat/issues/316), [#312](https://github.com/jmcollin78/versatile_thermostat/discussions/312), [#278](https://github.com/jmcollin78/versatile_thermostat/discussions/278)
+
+Pour s'en sortir, VTherm est équipé d'une fonction nommée auto-régulation qui permet d'adapter la consigne envoyée au sous-jacent jusqu'à ce que la consigne soit respectée. Cette fonction permet de compenser le biais de mesure des thermomètres internes. Si le biais est important la régulation doit être importante. Voir [L'auto-régulation](#lauto-régulation) pour configurer l'auto-régulation.

 ## Régler les paramètres de détection d'ouverture de fenêtre en mode auto

 Si vous n'arrivez pas à régler la fonction de détection des ouvertures en mode auto (cf. [auto](#le-mode-auto)), vous pouvez essayer de modifier les paramètres de l'algorithme de lissage de la température.

 The fourth parameter (``security_default_on_percent``) is the ``on_percent`` value that will be used when the thermostat enters ``safety`` mode. If you put ``0`` then the thermostat will be cut off when it goes into ``safety`` mode, putting 0.2% for example allows you to keep a little heating (20% in this case), even in mode ``safety``. It avoids finding your home totally frozen during a thermometer failure.

+## Centralized control
+Since release 5.2, if you have defined a centralized configuration, you have a new entity named `select.central_mode` which allows you to control all VTherms with a single action. For a VTherm to be centrally controllable, its configuration attribute named `use_central_mode` must be true.
+
+This entity is presented in the form of a list of choices which contains the following choices:
+1. `Auto`: the 'normal' mode in which each VTherm behaves as in previous versions,
+2. `Stooped`: all VTherms are turned off (`hvac_off`),
+3. `Heat only`: all VTherms are put in heating mode when this mode is supported by the VTherm, otherwise it is stopped,
+3. `Cool only`: all VTherms are put in cooling mode when this mode is supported by the VTherm, otherwise it is stopped,
+4. `Frost protection`: all VTherms are put in frost protection preset when this preset is supported by the VTherm, otherwise it is stopped.
+
+It is therefore possible to control all VTherms (only those explicitly designated) with a single control.
+Example rendering:
+
+![central_mode](/images/central_mode.png?raw=true)
+
+## Control of a central boiler
+Since release 5.3, you have the possibility of controlling a centralized boiler. From the moment it is possible to start or stop this boiler from Home Assistant, then Versatile Thermostat will be able to control it directly.
+
+The principle put in place is generally as follows:
+1. a new entity of type `binary_sensor` and named by default `binary_sensor.central_boiler` is added,
+2. in the VTherms configuration you indicate whether the VTherm should control the boiler. Indeed, in a heterogeneous installation, some VTherm must control the boiler and others not. You must therefore indicate in each VTherm configuration whether it controls the boiler or not,
+3. the `binary_sensor.central_boiler` listens for changes in state of VTherm equipment marked as controlling the boiler,
+4. as soon as the number of devices controlled by the VTherm requesting heating (ie its `hvac_action` goes to `Heating`) exceeds a configurable threshold, then the `binary_sensor.central_boiler` goes to `on` and **if a activation service has been configured, then this service is called**,
+5. if the number of devices requiring heating falls below the threshold again, then the `binary_sensor.central_boiler` goes to `off` and if **a deactivation service has been configured, then this service is called**,
+6. you have access to two entities:
+    - one of type `number` named by default `number.boiler_activation_threshold`, gives the trigger threshold. This threshold is in number of equipment (radiators) which requires heating.
+    - one of type `sensor` named by default `sensor.nb_device_active_for_boiler`, gives the number of devices requiring heating. For example, a VTherm having 4 valves including 3 heating requests will increase this sensor to 3. Only VTherm equipment that is marked to control the central boiler is counted.
+
+You therefore always have the information which allows you to control and adjust the activation of the boiler.
+
+All these entities are attached to the central configuration service:
+![The entities controlling the boiler](/images/entitites-central-boiler.png?raw=true)
+
+### Setup
+To configure this function, you must have a centralized configuration (see [Configuration](#configuration)) and check the 'Add a central boiler' box:
+
+![Adding a central boiler](/images/config-central-boiler-1.png?raw=true)
+
+On the following page you can configure the services to be called when switching the boiler on/off:
+
+![Adding a central boiler](/images/config-central-boiler-2.png?raw=true)
+
+The services are configured as indicated on the page:
+1. the general format is `entity_id/service_id[/attribute:value]` (where `/attribute:value` is optional),
+2. `entity_id` is the name of the entity that controls the boiler in the form `domain.entity_name`. For example: `switch.boiler` for boilers controlled by a switch or `climate.boiler` for a boiler controlled by a thermostat or any other entity which allows control of the boiler (there is no limitation). We can also switch inputs (`helpers`) like `input_boolean` or `input_number`.
+3. `service_id` is the name of the service to call in the form `domain.service_name`. For example: `switch.turn_on`, `switch.turn_off`, `climate.set_temperature`, `climate.set_hvac_mode` are valid examples.
+4. For some service you will need a parameter. This can be the 'HVAC Mode' `climate.set_hvac_mode` or the target temperature for `climate.set_temperature`. This parameter must be configured in the form `attribute:value` at the end of the string.
+
+Examples (to be adjusted to your case):
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:heat`: to turn on the boiler thermostat in heating mode,
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:off`: to stop the boiler thermostat,
+- `switch.pompe_chaudiere/switch.turn_on`: to turn on the switch which powers the boiler pump,
+- `switch.pompe_chaudiere/switch.turn_off`: to turn on the switch which powers the boiler pump,
+- ...
+
+### How to find the right service?
+To find the service to use, the best is to go to "Development tools / Services", look for the service called, the entity to order and the possible parameter to give.
+Click on 'Call Service'. If your boiler lights up you have the correct configuration. Then switch to Yaml mode and copy the parameters.
+
+Example:
+
+Under "Development Tools / Service":
+
+![Service configuration](/images/dev-tools-turnon-boiler-1.png?raw=true)
+
+In yaml mode:
+
+![Service configuration](/images/dev-tools-turnon-boiler-2.png?raw=true)
+
+The service to configure is then the following: `climate.empty_thermostast/climate.set_hvac_mode/hvac_mode:heat` (note the removal of the blank in `hvac_mode:heat`)
+
+Then do the same for the extinguishing service and you are all set.
+
+### The events
+
+Each time the boiler is successfully switched on or off, an event is sent by Versatile Thermostat. It can advantageously be captured by automation, for example to notify a change.
+The events look like this:
+
+An ignition event:
+```
+event_type: versatile_thermostat_central_boiler_event
+data:
+   central_boiler: true
+   entity_id: binary_sensor.central_boiler

+   parent_id: null

+

+   central_boiler: false
+   entity_id: binary_sensor.central_boiler
+   name: Central boiler

+   parent_id: null
+   user_id: null
+```
+
+### Warning
+
+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+> Controlling a central boiler using software or hardware such as home automation can pose risks to its proper functioning. Before using these functions, make sure that your boiler has safety functions and that they are working. Turning on a boiler if all the taps are closed can generate excess pressure, for example.

 This automation uses the excellent App Daemon named NOTIFIER developed by Horizon Domotique that you will find in demonstration [here](https://www.youtube.com/watch?v=chJylIK0ASo&ab_channel=HorizonDomotique) and the code is [here](https ://github.com/jlpouffier/home-assistant-config/blob/master/appdaemon/apps/notifier.py). It allows you to notify the users of the accommodation when one of the events affecting safety occurs on one of the Versatile Thermostats.

 ## Only the first radiator heats
 In `over_switch` mode if several radiators are configured for the same VTherm, switching on will be done sequentially to smooth out consumption peaks as much as possible.
-This is completely normal and desired. It is described here: [For a thermostat of type ``thermostat_over_switch```](#for-a-thermostat-of-type-thermostat_over_switch)
+This is completely normal and desired. It is described here: [For a thermostat of type ``thermostat_over_switch```](#for-a-thermostat-of-type-thermostat_over_switch)v
+
+## The radiator heats up even though the setpoint temperature is exceeded or does not heat up even though the room temperature is well below the setpoint
+
+### Type `over_switch` or `over_valve`
+With a VTherm of type `over_switch` or `over_valve`, this fault just shows that the parameters of the TPI algorithm are incorrectly set. See [TPI Algorithm](#tpi-algorithm) to optimize the settings.
+
+### Type `over_climate`
+With an `over_climate` type VTherm, the regulation is done by the underlying `climate` directly and VTherm simply transmits the instructions to it. So if the radiator heats up when the set temperature is exceeded, it is certainly because its internal temperature measurement is biased. This happens very often with TRVs and reversible air conditioning units which have an internal temperature sensor, or too close to the heating element (therefore too cold in winter).
+
+Example of discussion around these topics: [#348](https://github.com/jmcollin78/versatile_thermostat/issues/348), [#316](https://github.com/jmcollin78/versatile_thermostat/issues/316), [#312](https://github.com/jmcollin78/versatile_thermostat/discussions/312 ), [#278](https://github.com/jmcollin78/versatile_thermostat/discussions/278)
+
+To get around this, VTherm is equipped with a function called self-regulation which allows the instruction sent to the underlying to be adapted until the target temperature is respected. This function compensates for the measurement bias of internal thermometers. If the bias is important the regulation must be important. See [Self-regulation](#self-regulation) to configure self-regulation.
