UVR610 - the freely programmable controller

UVR610 - the freely programmable controller

The UVR610 freely programmable controller has the same technology as the UVR16x2 controller. The controller is programmed using the TAPPS2 software. Data transfer is done via Micro SD card or CAN bus. A 24V-output and/or the M-Bus interface can be activated by jumpers. The UVR610 housing is designed for control cabinets (45 millimetre standard installation bezel).

Available as:

  • UVR610
  • UVR610-OD (without Display)
  • UVR610-MODB (with Modbus Interface instead M-Bus)
  • UVR610-DC (with input for a 24V DC supply)

Universal controller - the x2-series

Whenever there’s talk about “universal controllers”, the topic is almost always our flagship, the UVR16x2. Many further variations have been released throughout the years. A DC-version, a variant with a 24V-output or an M-Bus interface, as well as extension modules with LAN, KNX and Modbus interfaces. All x2 devices run on the same in-house-developed operating system “x2 tech” and are therefore programmed and compatible in a unified manner.


  • UVR16x2
  • UVR610
  • RSM610

Housing form

The term “universal” not just refers to functionality, but also to structural makeup of our controllers. You will therefore find a suitable controller in the right casing (or without any casing, only a circuit board) for your application. Mounted in a control cabinet or on a boiler control panel, as a circuit board with or without integrated processing unit or the “classic” console to be mounted on a wall.

Extensions & interfaces

Expand your inputs and outputs via the CAN bus, auxiliary relays or extension modules via DL bus. The CAN-BC2 offers an interface for KNX, Modbus or M-Bus.
Furthermore, three-phase energy meters are available for currents of up to 300 A, fill level sensors, signal converters, immersion heaters or an entire DHW preparation unit.

Company profile

Building technology, intelligently regulated

Thermal solar systems had their first spike in popularity in the late 80’s. However, technicians and end users alike struggled with the usually overpriced and unreliable controllers. Ing. Kurt Fichtenbauer faced this problem together with a colleague and began developing his own solar system controller, in his own garage at first. Reliable, easy to operate and at a good price-performance ratio, these controllers quickly gained popularity.

Technicians with heart and soul

Today, DI Andreas Schneider runs the Technische Alternative, together with founder Kurt Fichtenbauer. The principles of product development haven’t changed. We develop reliable and universally deployable controllers, extensions and accessories for the entirety of building technology at fair prices.

Manufacturer-independent and flexible control of all energy-related components of building automation:

  • Heating
  • Cooling
  • Ventilation
  • Energy management
  • Solar & PV
  • Shading
  • Lighting

From an idea to serial production

Every device is developed and produced in our company’s site in northern Lower Austria, from an idea, to prototypes and finally to a finished product. All related software is also developed in-house, for programming and visualizations. Our own SMD assembly line guarantees high flexibility and quality from individual pieces up to serial production.
