Product description
The Logamatic LON-Gateway is incorporated into a LON network via a twisted pair cable (twisted
2-wire line). The twisted pair cable is protected against reverse polarity.
Defined data of the Buderus control panel is implemented with the Logamatic LON-Gateway
interface on standard network variable types (SNVTs) for the LON data bus. The communication
includes forwarding of error messages, operating messages, and actual values, as well as changing
of set points and operating modes for boilers and consumers.
