var kallað instabus

KNX -     the Worldwide STANDARD for Home and Bulding Control




 forritunartækið er ETS                            www.knx.org
hitanemarnir




               frá Berker
nokkrir kostir KNX hitastýringar

• KNX ræður við allar gerðir hitakerfa
• Hægt að hafa yfirsýn og stjórna kerfinu frá einum stað
• Hitanemi er margnotatæki, ljós, gluggar, tjöld og fl.
• Innbyggt sparnaðarkerfi, kjörhiti lækkaður, biðstaða
  og næturkerfi, allt að 30% sparnaður
• Mjög auðvelt að fínstilla hitanema
• Sjálfvirk lækkun á kjörhita við útloftun
• Öryggishitanemi í gólfi fyrir viðkvæm gólfefni
• Tengist margskonar skjámyndakerfum

• Gólfhitakerfi notar bakrás til uppblöndunar
• Öll gólfhitakerfi þurfa dælur
• Gólfefni hafa mikil áhrif á varmanýtingu
