Bonjour
j’ai depuis 15 ans une VMC double flux duolixMAX, pilotée via une télécommande qui remonte pas mal d’info
mais pas très paramétrable ni domotisable : réduire les ventilateurs quand il n’y a personne, augmenter le débit quand l’humidité monte dans la SDB pour ainsi optimiser la conso. La bébête consommait 50w 24h/24h ! Très utile quand on a tempo en jour rouge ou il faut optimiser sa conso.
j’ai donc démonté la carte interne, regarder la ref des ventilateurs :des embpapast, qui se pilotent par PWM ! bingo c’est pilotable via un ESP.
j’utilise donc une alim 230V/10V qui alimente une carte ESP32 4 relay :
- les relais me permettent de piloter le bypass et le grand début cuisine
- 2 sorties pwm pour piloter les ventilateurs (je peux ainsi piloter différemment l’aspiration ou le soufflage de manière à être bien à l’équilibre dans la maison). Il faut utiliser 2 transistors pour convertir le pwm qui sort de l’esp en 3v en pwm 10v. Ce convertisseur se trouve facilement sur Amazon ou alim pour qq euros. C’est souvent utilisé pour convertir le 3.3v en 5v.
- 2 entrées pour récupérer leur vitesse reel (RPM / rotation par minute)
- 4 sondes Dallas pour les températures des entrées/sorties d’air de la VMC
- 3 entrée analogique pour mesurer la tension d’alim + relire les tensions pwm.
Le tout monte dans un boîtier plastique a l’extérieur de la Vmc pour pouvoir intervenir facilement. Déjà 6 mois que ça tourne sans soucis.
Quelques automatisation pour déclencher un boost Sdb quand l’humidité est élevé, et me prévenir quand les filtres sont salles ( la conso augmente que c’est salle): ca m’a servie hier soir, il y avait un bouchon dans mes gaines → légère surconso détectée par une automatisation
