EBUS or EMS? #9

Closed barsmedia closed 6 years ago

barsmedia commented 6 years ago

Hello! I have old Junkers atmospheric boiler (ZWC28-1MF2K) and stumbled in docs about using E/BUS devices (thermostats etc.), so the question is: Does EMS is the same as EBUS older Junkers (Bosch) used? Also I have started upgrade my heating system (step by step), and have 2 MM100 controllers (for floor/radiators heating accordingly) that are 100% EMS devices, was thinking about creating virtual thermostats from sensors I have in my house -- is it possible?

The EMS bus is something else.

If you know a bit of programming and can take the time to reverse engineer the MM100 than maybe yes. But I guess the MM100 are also EMS slave devices so you still need an EMS master in the circuit, which would be the boiler.
