Climaveneta W3000 Modbus !free!
: Used to read digital outputs or status flags (e.g., Compressor On/Off).
: Power on the chiller. Navigate to the technical/factory menu using the password provided in your unit's documentation. Set the Modbus slave address and baud rate.
: By optimizing the operation of HVAC systems, the Climaveneta W3000 Modbus contributes to improved operational efficiency. This not only reduces energy costs but also extends the lifespan of HVAC equipment.
Use the W3000 onboard display to set a unique Slave ID and verify standard protocol settings (e.g., 19200, 8, N, 1).
While exact register mappings can vary slightly based on the specific Climaveneta software version installed, standard parameters include: Parameter Name Modbus Address Example Scale / Unit 0 = Off, 1 = On Chilled Water Inlet Temp Input Register Chilled Water Outlet Temp Input Register Active Cool Setpoint Holding Register Compressor Run Status Discrete Input 0 = Stopped, 1 = Running General Alarm Code Input Register Integer ID climaveneta w3000 modbus

Do you have the for your specific software version (e.g., CA15)?
if you want the BMS to control the unit rather than just monitor it. Modbus Mapping & Data
: A dedicated BMS serial card (often an RS485 interface) must be inserted into the designated "BMS Card" slot on the W3000 board. Physical Connection
The W3000 exposes both (read-only) and Holding Registers (read/write). Common points include: Set the Modbus slave address and baud rate
The is a sophisticated microprocessor controller designed for HVAC units like chillers and heat pumps. It serves as the "brain" of the system, managing complex algorithms for energy efficiency, compressor balancing, and fault diagnostics. Integrating via Modbus
Apply correct decimal scaling on the BMS side to ensure accurate temperature monitoring.
Both "On/off enable" and "Operating mode enable" must be set to "Yes" in the supervisor menu to allow remote control. Hardware Connection (RS485)
What is your (e.g., Schneider, Siemens, or a custom Raspberry Pi)?
The W3000 implementation utilizes standard Modbus application layer function codes to read and write data points:
