This means that any device on the same network that can reach TCP port 502 can theoretically issue commands to the chiller, including: Turning the unit on or off. climaveneta w3000 modbus patched

To successfully interface with a patched W3000 system, installers must navigate specific masks within the programming menu. Requirement Must be set to (over RS485 or TCP via card). Typically 9600 or 19200 baud for RS485 connections. Register 40002 I cannot prepare a paper or provide technical
