I still adhere to my opinion.
Here are the compatible controllers:
● Vitotronic 200, Typ HO1, HO1A, HO1B, HO1D, HO2B
● Vitotronic 200 RF, Typ HO1C, HO1E
● Vitotronic 200, Typ KO1B, KO2B, KW6, KW6A KW6B, KW1, KW2, KW4, KW5
● Vitotronic 300, Typ KW3
● Vitotronic 200, Typ WO1A, WO1B, WO1C
● Vitoligno 300-C with Ecotronic and Software Version 2.12 or higher
● Vitoligno 200-S with Ecotronic and Software Version 2.04 or higher
● Vitoligno 300-P with Vitotronic 200 FO1
The Vitodens 111-W doesn´t have one of these controllers.
