Note:
Modbus is an application protocol to exchange messages between intelligent Modbus controllers in the
building management system. The Modbus protocol “TCP” is used in the HERZ control. This protocol
transmits the encoded data via LAN cable. Modbus ensures that connected controllers in the building
management system receive the transmitted data from the boiler, so they can continue processing.
