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.
