2. Description

The RS485 interface allows sauna control units in the Professional Series
(Pro-B2, Pro-B3, Pro-C2, Pro-C3) to be connected to a domestic bus system
using an RS-485 connection and a configurable protocol.
This interface documentation provides a text-based communication protocol which
allows the majority of the Professional Series functions to be controlled remotely.
For the physical connection, the sauna control units in the Professional Series
are equipped with an RJ45 socket. In addition, the Connectivity Set (item no.
Pro-CS) is required.
Scope of delivery of the Connectivity Set (item no. Pro-CS)
● Network cable 0.5 m
● RJ45 to print terminal adapter
● 120 W terminating resistor
