The product purchased (Vitodens 100) is very good indeed, and fitted by a very competent and professional company. However, the instruction manual does not include instructions on operating the clock. I emailed Viessmann shortly after installation was complete, (01.10.2017) requesting further information/clarification, but still await a reply.
