=== '''ED module:''' ===
This is a general term for all devices that have a communication protocol that allows work between the PCB responsible for the IP section and the main PCB called the ED module.
There are 4 devices equipped with ED communication: HS06N, HS06NWL, HWK, HWKL.

The Web Service section in the Controller tab has the "ED Module" tab that allows you to configure ED devices.

=== ED bus: ===
This is a specialist 1-wire protocol that allows bilateral communication between the IP section and the ED module. Communication takes place with one wire, the bus is carried out on a yellow cable on a 3-pin connector. Each subordinate device in addition to the communication cable needs power cables (GND and 12VDC) to work.

All devices already have factory connections, the installer does not have to prepare it
