E' NATA LA NUOVA APP DI O.ERRE. O.Tech è in grado di configurare e comandare i recuperatori di calore Ghost di O.ERRE installati all'interno della vostra abitazione in modo semplice e immediato anche se ci si trova lontano da casa. I vari recuperatori possono essere configurati automaticamente o in modo manuale così che si comportino come un unico sistema di ventilazione oppure possano essere gestiti come unità singole di ventilazione. Con O.Tech sono impostabili più di dieci differenti modalità di funzionamento (Automatica, Manuale, Sorveglianza, Smart, Fuori Casa, Espulsione Temporizzata, Notte, Immissione, Estrazione, Flussi d'aria) e quattro portate d'aria. O.Tech si collega alle centraline metereologiche per la rilevazione delle condizioni ambientali esterne ed è in grado di monitorare lo stato della qualità dell'aria dell'abitazione tramite un sensore VOC installato a bordo macchina.
