  • the lapsed time T between the event and the removal of the application program from the mobile communication module 2 may be an absolute pre-set time (e.g. x days), a calculated time, e.g.
  • the de-installation may be triggered by an event, e.g. a command entered by the user, by actuation of a virtual button, by interrupting the short range communication, at certain intervals, e.g. on a particular day of the week or a particular time of a day, etc.

Abstract

Un dispositif de terrain (1) dans un système de commande HVAC comprend au moins une partie mécanique (10) comprenant par exemple un actionneur, un capteur ou tout autre dispositif permettant de gérer l'écoulement de fluide dans un tuyau du système HVAC. En outre, le dispositif de terrain (1) comporte un dispositif de commande (11) comprenant une première interface de communication sans fil à courte portée (112), par exemple un transpondeur NFC. Un dispositif de communication mobile (2) a une seconde interface de communication sans fil à courte portée (22) et une première interface de communication à longue portée (23). Lorsqu'une communication à courte portée est établie entre le dispositif de terrain (1) et le dispositif de communication mobile (2), un programme d'application est automatiquement téléchargé d'un serveur de données (3) sur le dispositif de communication mobile (2) et est exécuté. Le programme d'application est temporairement installé sur le dispositif de communication mobile (2).
