What is the of your W3000 (e.g., LA12, CA15)? For many older installations using the Carel pCOWeb

A patched Modbus interface has been successfully applied to the Climaveneta W3000 unit controller. The patch addresses:

The Climaveneta W3000 is designed to manage complex thermodynamic cycles in chillers and heat pumps. It monitors temperature sensors, pressure transducers, and compressor states to optimize performance. To provide facility managers with remote visibility, the controller supports Modbus RTU (over RS485) Modbus TCP/IP (over Ethernet)

Historically, the W3000 platform, particularly when deployed with the optional Ethernet gateway (CGW), was susceptible to unauthorized Modbus TCP access due to a lack of authentication and a factory-default "unlocked" mode. The "Modbus Patched" designation typically refers to a firmware or configuration update that mitigates unauthorized access by enforcing stricter register access controls or requiring explicit unlocking sequences.
