 Le deuxième délai (security_delay_min) est le délai maximal entre deux mesures de température avant de régler le préréglage sur ``security`` et d'éteindre le thermostat. Si le capteur de température ne donne plus de mesures de température, le thermostat et le radiateur s'éteindront après ce délai et le préréglage du thermostat sera réglé sur ``security``. Ceci est utile pour éviter une surchauffe si la batterie de votre capteur de température est trop faible.
 
+Le troisième paramétre (security_min_on_percent) est la valeur minimal de on_percent en dessous de laquelle le préréglage sécurité ne sera pas activé.
+Mettre ce paramètre à ``0.00`` déclenchera le préréglage sécurité quelque soit la dernière consigne de chauffage, à l'inverse ``1.00`` ne déclenchera jamais le préréglage sécurité.

 The second delay (security_delay_min) is the maximal delay between two temperature measure before setting the preset to ``security`` and turning off the thermostat. If the temperature sensor is no more giving temperature measures, the thermostat and heater will turns off after this delay and the preset of the thermostat will be set to ``security``. This is useful to avoid overheating is the battery of your temperature sensor is too low.
 
+The third parameter (security_min_on_percent) is the minimal on_percent value below which the security preset won't be trigger. If you set it to ``0.00`` security preset will be trigger regardeless of the heating on_percent when there is a temperature loss, at the opposite ``1.00`` will never trigger the security preset.

     1. The ``security`` preset is a hidden preset. You cannot select it manually or by the preset service,
     2. When the temperature sensor will comes to live and re-send temperatures, the preset will be restored to its previous value,
     3. Beware that two temperatures are needed: internal temp and external temp and each should give temperature else the thermostat will be in ``security`` preset.
