The Multi-Smart multifunctional module is designed to control central heating and ventilation systems (destratifier or free cooling). It generates a Wi-Fi signal that enables the user to establish a local connection via a smartphone or iOS-compatible tablet. Several configurable functions enable the user to control boilers, pumps, motorized valves, and fans according to temperature measurements and programmes hours. In order to use certain functions, the Multi-Smart must be combined with one or more programmable room thermostats. Possible functions Control of a boiler and pumps for domestic hot-water production without three-way valve Control of a boiler, pumps, and a three-way valve for domestic hot-water production Control of a boiler and up to four pumps or zone valves in a multi-zone system Cascade control of two boilers depending on the outside temperature Pump or three-way valve control in a system with solar panels Control of destratifier fan Control of a variable-speed pump in a co-generation unit Control of a boiler, domestic hot-water production, and a heating circuit that can be temperature-adjusted according to the room temperature Control of a mixing valve and two pumps to ensure constant temperature control of hot water in a domestic heating system or domestic hot-water circuit Control of a boiler, a mixing valve, and two pumps for outdoor temperature control Control of a variable-speed fan in a free-cooling installation. Inputs and outputs The Multi-Smart is powered by 230 V. It has two inputs for PTC thermistor probes, four inputs for connections, five outputs with connections for boiler, pump, valve, fan control and a 0-10 V output for modulating boiler or variable-speed pump or fan.

HVAC POSITIONER ist die erste und einzige App, die Ihre HVAC-Anlage (Wärmepumpe, Kältemaschine, etc.) virtuell in einer realen Umgebung platziert (AR). Die implementierte Echtzeit-Schallausbreitungsrechnung ermöglicht es Ihnen, die HLK-Anlage perfekt nach den aktuellen Vorschriften und persönlichen Vorlieben zu positionieren. Die AIT Austrian Institute of Technology GmbH hat ein Verfahren entwickelt, um die Lärmemissionen der Bevölkerung in städtischen Gebieten zu minimieren. Diese Methoden ermöglichen einen einfachen, intuitiven und gleichzeitig präzisen Umgang mit den Geräuschemissionen. Nutzen Sie die App vor der Installation Ihrer HLK-Anlage und platzieren Sie sie virtuell vor Ort in einer realen Umgebung mit Augmented Reality. All die angeführten Entwicklungen werden am AIT Austrian Institute of Technology GmbH durchgeführt. Teilweise entstammen die zugrundeliegenden Methoden dem Forschungsprojekt RAARA (Residential Area Augmented Reality Acoustics, Projektnummer 873588), welches im Rahmen der 6. Ausschreibung „Stadt der Zukunft“ gefördert wird. „Stadt der Zukunft" ist ein Forschungs- und Technologieprogramm des Bundesministeriums für Klimaschutz, Umwelt, Energie, Mobilität, Innovation und Technologie (BMK). Es wird im Auftrag des BMVIT von der Österreichischen Forschungsförderungsgesellschaft gemeinsam mit der Austria Wirtschaftsservice Gesellschaft mbH und der Österreichischen Gesellschaft für Umwelt und Technik (ÖGUT) abgewickelt.
