Viessmann Vitodens 222-W WS2A + Vitotrol 300 thermostat and Vitotronic 200 exterior sensor + Tado X?
Hello, can anyone suggest a technician in Brussels area who is familiar and able to remove the Vitotrol 300 wired thermostat (not compatible with TadoX) and connect/wire the Tado X wireless receiver to our boiler? We have had no luck so far, 2 technicians could not do it, there seems to be an issue due to the exterior sensor… Or anyone with the same boiler maybe can post the pictures of the tado x (not V3) receiver correct wiring to the type of boiler we have? App recognized the receiver but gave an error message and the heating on demand did not start.

@DinaZ No help with the technician. However here
- 5592911VMA00001_1.PDF is a link to the installation instructions for the Vitotrol 300 thermostat control, and it includes the wiring instructions.
- 5458905 GB Vitotronic 200 KO1B, KO2B Installation.pdf is the link to the external sensor and decribes the bus connections.
Would this help your heating engineers?
