 Le quatrième param§tre (``security_default_on_percent``) est la valeur de ``on_percent`` qui sera utilisée lorsque le thermostat passe en mode ``security``.

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.

+## 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 indiqué 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 indiqué dans chaque configuration de VTherm si il contrôle la chaudière ou pas,
+3. le `binary_sensor.central_boiler` écoute les changements d'états des VTherm marqués comme contrôlant la chaudière,
+4. si l'un des VTherm écoutés demande du chauffage (ie son `hvac_action` passe à `Heating`), 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 plus aucun VTherm écoutés ne demande du chauffage (ie aucun `hvac_action` n'est `Heating`), alors le `binary_sensor.central_boiler` passe à `off` et si un service de désactivation a été configuré, alors ce service est appelé.
+
+Vous avez donc en permanence, un indicateur qui donne l'info que au moins un des radiateurs est à besoin de chauffer.
+
+### 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

+  central_boiler: true
+  entity_id: binary_sensor.central_boiler

+### 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.

 ### 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).

 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.

 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.

+Since version 5.3 it is possible to deactivate the safety device following a lack of data from the outdoor thermometer. Indeed, this most of the time having a low impact on regulation (depending on your settings), it is possible that it is absent without endangering the home. To do this, you must add the following lines to your `configuration.yaml`:

+## 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 the VTherms marked as controlling the boiler,
+4. if one of the listened VTherms requests heating (ie its `hvac_action` changes to `Heating`), then the `binary_sensor.central_boiler` changes to `on` and if an activation service has been configured, then this service is called,
+5. if no more listened VTherm requests heating (ie no `hvac_action` is `Heating`), then the `binary_sensor.central_boiler` goes to `off` and if a deactivation service has been configured, then this service is called.
+
+You therefore always have an indicator which gives information that at least one of the radiators needs to be heated.
+
+### 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
+   user_id: null
+```
+
+An extinction event:
+```

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

+context:
+   id: 01HM3VZRJP3WYYWPNSDAFBRW1T
+   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.

 ### 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: [#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.
