1988

Already in the founding year, 500 simple solar controllers sold.

1989

Development of multi-circuit controllers. Mass-produced display screen and delivery with all necessary accessories as a complete package caused rapid growth; the number of units sold reached 1500.

1992

Solar computer SLC64 was the first device on the European market to enable selection from numerous hydraulic schemes and control programs via entry of a program number.

1995

Tests and introduction of the first speed-control process for simple circulation pumps. All controllers were processor-controlled and had a data output for remote display and data logging.

1996

New speed technology based on wave packets, unique in Europe.
Inclusion of considerably more hydraulic schemes and functions in the standard control programs.
First controller patented for sanitary water heating.

1998

Product range expanded to include heating circuit controllers and heat meters.
TA was the first European company to integrate an intelligent solar start function.

1999

Manufacture began to change over to SMD.
Second patent for sanitary water heating.

2000

Development of the freely programmable controller UVR1611 began.

2002

Already in the first year of manufacture of the UVR1611, one of the very first freely programmable heating devices, more than 3000 units were delivered.
The programming platform TAPPS for UVR1611 was introduced.
The bootloader, a data hub between PC and UVR1611 controller, was also completed.

2003

Introduction of the simple solar controller ESR21 and single/triple circuit universal controller UVR61-3.

2004

CAN bus technology for UVR1611 in a network.

2005

Further development of data analysis for simple solar controllers.
USB interface for bootloader completed.

2006

All electronics manufacture changed over to a lead-free soldering process.
Ethernet connection on the bootloader enabled access to the UVR1611 control technology over the Internet.
