Boilers with EMS control bus

EMS

— it is a control bus used mainly in Bosch and Buderus units. In general, it is characterized by extensive functionality, a high degree of automation and the ability to create extensive control systems. However, note that nowadays, you can find both the original EMS and the modified EMS Plus and these standards are not initially compatible with each other (although support for both of them may well be provided in some devices). So the specific version of the EMS bus should be specified separately. Note that the Bosch units mainly use the original version, and the Buderus devices use EMS Plus (although exceptions are possible here and there).
