Heating, cooling, ventilationwith KNXSystems and products
Networking of theroom automation functions If class A is to be achieved according toEN15232, the following is necessary:1. networking of energy-efficient roomautomation functions for allapplications2. demand-oriented control KNX fulfills all technical requirements forthe integration and communication of thedifferent applications and products The integration of HVAC technology inhome and building automation has longbeen part of standard KNX applications Currently over 70 manufacturers haveregistered KNX products with heating,ventilation and air conditioningapplicationsKNX Association InternationalKNX has already shown in a variety ofstudies and projects that savings of 50 %to 60 % can be achieved throughindividual room control and ventilationcontrol alone.KNX: The worldwide STANDARD for home & building controlPage No. 20April 2017
Individual room temperature controlIndividual room temperature controloffers the possibility of regulatingthe room temperature of a singleroom regardless of the temperaturein other rooms. The current controllers aremainly complete, aestheticallysophisticated room controllerswhich also control all the otherfunctions in a room. Some of the current controllerscan also measure the CO2content and air humidity as wellas support the heating and / orcooling operating modes.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 21April 2017
Radiator and underfloor heating,cooling ceilingsValves control the rate of flow in theindividual heating and cooling circuits The triggering of the valves is normallycarried out via analogue thermoelectricor motor valve drives. Motor valve drives with an integratedKNX interface. can be very precisely positioned mostly have additional intelligenceand diagnostic functions transfer both the current valveposition and error messages viaKNXKNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 22April 2017
Fan coil controllersA benefit of fan coil control is the rapidavailability of thermal energy or coolingcapacity. It is therefore widely used in hotelsand office buildings. The control of the fan and the heating orcooling register is carried out via special KNXfan coil actuators in the unit while theoperation is usually carried out via KNX roomthermostats with extended functions andsetting options. It is possible via KNX to separate the unitand the operation cost-effectively in terms ofrooms.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 23April 2017
Interfaces to energy generationand distribution systemsWith interfaces to power generation systems it is possible: to display the current state of their heating system using the KNXvisualisation system to predefine setpoint values and set operating modes Fault signals are automatically transmitted to KNX and displayed As the current heat requirement in the rooms can be communicatedvia the KNX gateway to the heating controllers, the heat generationmust be precisely matched to the current demand.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 24April 2017
Variable volume flow controller Based on the recorded room conditions andthe current air requirement, energeticallyintelligent and demand-controlled systemscan be set up with KNX. A central control unit permanently monitorsthe flap positions of the individual VAV boxesvia KNX. If the flaps eliminate excessive inletpressure, this is reduced. The aim is to operate the system with thelowest possible pressure loss.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 25April 2017
Room air control and interfacesto ventilation systems In addition to the baseline values, thevalues for the room temperature, airhumidity and carbon dioxide contentmeasured by the KNX individual roomcontrollers and air quality sensors can betransferred via the KNX interfaces to theventilation system and taken into accountduring the control. In the other direction, the ventilationsystem transfers status signals to KNXwhich for example signal the necessaryreplacement of ventilation filters.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 26April 2017
Interfaces to distributedair conditioning systems The interfaces to the air conditioning systems are versatile. Inaddition to a few standardised interfaces, the manufacturers use avariety of proprietary hardware and protocol solutions. Special KNX gateways enable the integration of almost all the airconditioning devices into KNX.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 27April 2017

Heating, cooling, ventilationwith KNXExample 2A thinking home
A thinking homeIntelligent home automation with KNX All components of home automation, such aslighting, blinds, heating and room temperaturecontrol, window contacts, weather station, etc.are networked via KNX and can be centrallycontrolled. Functional examples: the blinds close when the TV is switchedon the letterbox reports when the post hasbeen delivered the socket with an iron plugged inswitches off when nobody is in the roomThe “smarthouse213” of Ute andMatthias Schmidt from Coburg (Germany)The fact that the heating system supplies heat as required independently of the outside temperature, helpssave energy. “Demand-based heating works better with KNX 10 than before, as the valve position of theradiators and the exact room temperature are now reported to the heat generator. The actual temperaturecan thus be compared with the desired temperature and the boiler ‘knows’ whether it should heat or not,”Matthias Schmidt explains.KNX Association InternationalKNX: The worldwide STANDARD for home & building controlPage No. 34April 2017
A thinking homeBuderus heating system supplies heat aspart of KNX home automation The Buderus heating system is integrated intothe home automation system via the KNX 10gateway The single-room control unit allows thedesired temperatures to be set manually forindividual rooms. When open windows are detected, the roomtemperature control unit receives thisinformation, switches to frost protection modeand closes the radiator valves. The Buderus heat generator is informed thatno heat is needed and stops heating.KNX Association InternationalThe “smarthouse213” of Ute andMatthias Schmidt from Coburg (Germany)KNX: The worldwide STANDARD for home & building controlPage No. 35April 2017
