Technische Alternative RT GmbH products

Universal controller with more than 800 adjustable programs. Datalogging and function data transfer options using SD card or CAN bus. The UVR67 universal controller features various thermostatic, differential temperature, speed control and heating circuit control functions for use in solar thermal and heating systems. The required control function is called up by entering the relevant program number. The UVR67 is the successor to the UVR65 and represents a progression in development. Also, it replaces the devices UVR61-3, UVR61-GT, UVR63, UVR63-H and the HZR65.

The ESR21 unit is a multi-purpose differential controller. Additional information can be read in via the DL bus. Thus, in parallel to the controller operation (solar system) it is also possible to calculate the yield (thermal energy). The range of use extends from the single circuit solar system through to sanitary water treatment by way of pump speed control.

The CAN-TOUCH is a 9.7” LCD touch screen. The software TA-Designer can be used to create a personalized graphical interface with a virtually unlimited number of pages, transferrable to the device via SD card. Individual pages can be protected with PIN codes. Messages can be displayed via pop-up windows.

Like the CAN-EZ2, the new CAN energy meter records electrical and thermal energy flows. It is programmed using TAPPS2 software.

ATON is a plug & play solution for using surplus PV energy – without additional wiring. It consists of an energy meter and an immersion heater, which can be variably controlled from 50 W to 3 kW, for installation in a buffer cylinder. Through a wireless connection, the energy meter (x2-tech) specifies the output the immersion heater can consume. The immersion heater sends all measurements (high limit safety cut-out, internal temperature and the values of the two external sensors) back to the energy meter.
