NB Ventilation har flere \u00e5rs erfaring i opbygning af aggregater med OJ Air2 automatik.<\/p>

Aggregatet er f\u00e6rdigbygget med komplet Air2 automatiksystem og er konfigureret og testk\u00f8rt f\u00f8r afsendelse fra fabrikken med medf\u00f8lgende el-dokumentation og brugervejledning.<\/p>

Automatikken kombineret med et aggregat skr\u00e6ddersyet efter kundens \u00f8nsker muligg\u00f8r en l\u00f8sning\u00a0optimeret\u00a0mht. til \u00f8konomi og energieffektivitet uden at g\u00e5 p\u00e5 kompromis med funktionaliteten.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/header>\n\t\t\t\t

Betjening<\/h2><\/div>

Ventilationsaggregatet betjenes fra et touchdisplay. Fra den kan man overv\u00e5ge og indstille aggregatets funktion.<\/p>

  • Man vil kunne se en log over v\u00e6rdierne for temperatur, tryk og luftm\u00e6ngde op til syv dage tilbage.<\/li>
  • Sprog i display kan indstilles til bl.a. dansk, norsk og engelsk.<\/li>
  • Der kan ops\u00e6ttes forskellige adgangsniveauer til forskellige brugergrupper ved hj\u00e6lp af en brugerflade med flere niveauer.<\/li><\/ul><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Webinterface<\/h2><\/div>

    Derudover fungerer Air2 regulatoren ogs\u00e5 som en webserver og kan tilkobles ethernet netv\u00e6rk. Aggregatet kan derved overv\u00e5ges og betjenes fra en hvilken som helst PC, som er tilkoblet samme netv\u00e6rk. Hvis der konfigureres port-forwarding p\u00e5 routeren, kan aggregatet ogs\u00e5 styres over internettet.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Kommunikation<\/h2><\/div>

    N\u00e5r det kommer til inkorporering i eksisterende bygningsautomatik,\u00a0er aggregatet\u00a0forberedt til flere kommunikationsprotokoller.\u00a0Aggregatet er ogs\u00e5 i stand til at regulere som en selvst\u00e6ndig enhed uafh\u00e6ngigt af andet automatik.<\/p>

    • Modbus:<\/strong>\u00a0Aggregatet er fra fabrikken forberedt for Modbus kommunikation, hvorigennem alle parametre for aggregatet kan tilg\u00e5s. Modbus er den de-facto standard inden for industriel kommunikation med bl.a. CTS systemer. Regulatoren har interface b\u00e5de til Modbus RTU 6P6C stik og Modbus over TCP\/IP netv\u00e6rk.<\/li>
    • BACnet:<\/strong>\u00a0Aggregatet er fra fabrikken forberedt for BACnet kommunikation over TCP\/IP, hvorigennem alle parametre for aggregatet kan tilg\u00e5s. BACnet er en af de f\u00f8rende standarder inden for industriel kommunikation med bl.a. CTS systemer.<\/li>
    • Digitale ind- og udgange:<\/strong>\u00a0Der er klemmer klar til tilkobling af\u00a0digitale indgange til styring af f.eks. start, stop og skift mellem h\u00f8j og lav hastighed.<\/li><\/ul><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      Drift<\/h2>

      Ved opstart af aggregatet fra stoppet tilstand, vil f\u00f8lgende ske:<\/p>

        1. Udsugningsventilatoren starter f\u00f8rst samtidig med, at varmegenvindingen og varmefladen overstyres.<\/li>
        2. N\u00e5r udsugningsventilatoren er kommet op i hastighed, startes indbl\u00e6sningsventilatoren. Denne funktion forhindrer frostfare under opstart.<\/li>
        3. N\u00e5r indbl\u00e6sningssventilatoren er kommet op i hastighed, frigives overstyringen, og aggregatet k\u00f8rer som normalt.<\/li><\/ol><\/li><\/ol>

          Aggregatet kan skifte mellem forskellige driftsformer med hver deres indstillinger for regulering af aggregatet:<\/p>

          • Stop: Aggregatet er stoppet.<\/li>
          • Lav hastighed: Aggregatet k\u00f8rer konstant i henhold til indstilede parametre for lav.<\/li>
          • H\u00f8j hastighed:\u00a0 Aggregatet k\u00f8rer konstant i henhold til indstillede parametre for h\u00f8j.<\/li>
          • Ugeprogram: Aggregatet k\u00f8rer i henhold til indstillet ugeprogram. Ugeprogrammet kan indstilles for hver enkelt dag i ugen. For hver dag kan man indstille flere tidsperioder, hvor aggregatet henholdsvis kan v\u00e6re stoppet, k\u00f8re lav hastighed eller h\u00f8j hastighed.<\/li><\/ul>

            Det er muligt at indstille forl\u00e6nget drift, hvor aggregatet kan k\u00f8re samme driftsform over flere dage.<\/p>

            Uret skifter automatisk mellem sommmer- og vintertid.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

            Der er klemmer klar til tilkobling af ekstern signal til at styre aggregatet til at k\u00f8re lav hastighed, h\u00f8j hastighed eller at stoppe.
            Indgangen til h\u00f8j hastighed kan indstilles med efterl\u00f8bstid s\u00e5dan, at den vil k\u00f8re h\u00f8j hastigihed et stykke tid efter, at signalet brydes.\u00a0
