Technische Alternative RT

What Technische Alternative RT does

Technische Alternative RT GmbH is an Austrian family-owned designer and manufacturer of freely programmable controllers and building-automation hardware, founded in 1989 by Ing. Kurt Fichtenbauer and Roman Zimmel and headquartered in Amaliendorf, Lower Austria, with approximately 70 employees. The company's product platform centers on the x2 series of universal controllers (UVR16x2, UVR610S/K, UVR67) and a proprietary three-layer communication stack — CAN-Bus, DL-Bus and CORA (wireless/wired) — that interconnects controllers, extension modules, sensors, and actuators for heating, cooling, ventilation, solar thermal, fresh-water, and energy-management applications. Software is a strategic pillar: TAPPS2 (logic-block programming), TA-Designer (visualization) and Winsol (data logging) are distributed as freeware, while a TA Wiki, YouTube channel and multi-day seminars in Austria and Germany build installer expertise. The commercial model is indirect: hardware is sold primarily through specialist trade partners (heating engineers, electrical installers, plumbing professionals) and via OEM integrations into heat pumps, biomass boilers and ventilation systems, with end customers referred to certified specialists. Revenue is generated from hardware sales of controllers, sensors, extension modules, power-to-heat (ATON family) and fresh-water (FRISTAR3) subsystems, supplemented by programming services, repair services for legacy units, and paid seminars; pricing is not publicly disclosed. The company holds a Klimabündnis Betrieb sustainability certification, operates in 40+ countries with 10,000 active CMI web-portal users, and continues to release new products and inverter-integration examples across 2025-2026.

Core offering

Technische Alternative RT designs, manufactures, and sells freely programmable universal controllers (x2 series: UVR16x2, UVR610S, UVR610K) and standard controllers for heating, solar, cooling, ventilation, and building automation applications. The portfolio also includes CAN-Bus extension modules, sensors, energy meters (CAN-EZ3), power-to-heat systems (ATON), fresh water stations (FRISTAR3), and free programming/visualization software (TAPPS2, TA-Designer, Winsol), sold to specialist trade partners and OEM manufacturers across the DACH region and 40+ countries.

Product overview

Technische Alternative RT develops and manufactures intelligent controllers for building automation and energy management. The product portfolio centers on the freely programmable x2 series of universal controllers (UVR16x2, UVR610S, UVR610K) as the core platform, supported by operating interfaces (CAN-MTx2, CMI, CMI-S), extension modules (CAN-BC2, CAN-I/O45), and energy management devices (CAN-EZ3, ATON power-to-heat system). The system is extended through sensors (temperature, humidity, flow, pressure), pump groups and fresh water stations (FRISTAR3), and standard controllers (UVR67, ESR32). Free software includes TAPPS2 for programming, TA-Designer for visualization, and Winsol for data analysis. The modular architecture supports building heating, cooling, ventilation, solar, and smart home applications across residential and commercial installations.

Broad incumbents

• Schneider Electric (EcoStruxure): Global energy management and automation company with EcoStruxure Building platform. Comparable as a broad incumbent competing across building automation, energy management, and HVAC control in commercial and industrial customers.
• Siemens Smart Infrastructure: Large German industrial conglomerate competing in building automation (Desigo) and HVAC control. Comparable as a much larger incumbent offering programmable controllers and BMS for the same commercial and infrastructure segments TA serves.
• Honeywell Building Technologies: Global incumbent in HVAC controls, building automation, and energy management. Comparable as a broad-line competitor in the same end markets with much larger scale and deeper enterprise distribution.
• Viessmann (Building Solutions): German premium HVAC and heat pump manufacturer with own controls platforms and Vitotronic controllers. Comparable because it is both a customer (OEM for TA-compatible controllers) and a competitor for integrated heating system control.

Direct peers

• Belimo: Swiss global leader in HVAC field devices (actuators, valves, dampers) and increasingly energy valves and controls. Directly comparable because Belimo makes programmable control hardware interfacing with TA's controllers (Modbus integration documented) and competes in the same HVAC control value chain.
• Theben: German-based manufacturer of KNX building automation, HVAC control, and timer/lighting controls. Comparable as a DACH-rooted peer targeting HVAC installers and building automation with programmable controllers and presence in similar channels.
• Kieback&Peter: German building automation specialist producing DDC controllers and building management systems. Directly comparable as a similarly sized DACH-headquartered competitor in programmable HVAC and building automation controllers for residential and commercial projects.
• Fr. Sauter AG: Swiss-based manufacturer of building management systems, DDC controllers, and HVAC control valves. Comparable as a mid-sized DACH peer in programmable building/HVAC automation serving similar commercial and district-heating customers.
• WAGO Kontakttechnik: German manufacturer of programmable controllers, I/O systems, and fieldbus couplers (BACnet, KNX, Modbus). Comparable as a competing supplier of freely programmable controllers and bus-based automation for building and HVAC applications.

Emerging players

• LOXONE: Austrian smart home automation specialist with programmable Miniserver and broad HVAC/energy integration. Comparable as a regional peer in DACH offering freely programmable home/building automation with focus on installers and direct installers.
