Climaveneta W3000 Modbus ((hot))

On/Off enable and Operating Mode enable must be set to "Yes" Hardware & Installation Integration typically requires a dedicated Serial Interface Card

: The system provides a detailed record of historical trends and active alarms, which can be transmitted via Modbus for immediate technician notification. Available Interfaces

Assign a unique ID to each chiller on the loop (Range: 1 to 247). Modbus TCP Settings

Example: A register reading of 745 translates to 74.5°C or 74.5°F in the BMS software. Critical Monitoring Registers (Read-Only) Register Function Typical Register Type Description Chiller Status Input/Holding Indicates current state (Off, Cooling, Heating, Defrost) Evaporator Inlet Temp Input/Holding Temperature of water entering the unit Evaporator Outlet Temp Input/Holding Temperature of water leaving the unit Condenser Inlet/Outlet Input/Holding Water loop or air ambient temperatures Compressor Run Status Coil/Discrete Input

These registers allow the supervisor system to alter unit behavior based on building occupancy or peak-demand shaving strategies. climaveneta w3000 modbus

To enable Modbus communication, the W3000 controller must be equipped with a specific .

Check for reversed polarity on the RS485 line (swap A and B ).

You must enable supervisor control in the controller settings to allow the BMS to send commands (like On/Off or changing operating modes). : On/Off enable : Set to Yes . Operating mode enable : Set to Yes . Serial Settings : Protocol : Modbus.

Set the supervisory protocol to Modbus (sometimes labeled as Carel or Standard Modbus depending on the specific electronic board variant). Phase 2: Diagnostic Testing via PC On/Off enable and Operating Mode enable must be

Note: Register addresses can be presented as 0-based (Hexadecimal/Protocol addressing) or 1-based (Decimal/User addressing). Always check if your BMS master requires an offset of 1. 1. Key Status Indicators (Inputs/Coils)

What is the specific you are integrating with (e.g., Honeywell, Johnson Controls, a custom PLC)?

The W3000 family includes several physical interface versions to suit different machine sizes: W3000 Controller Interface Manual - Heat Pump - Scribd

The master device (BMS) and the slave device (W3000) must share identical serial communication profiles. Ensure your W3000 matches these settings: Typically configurable to 9600 or 19200 bps. Data Bits: 8 bits. Parity: Usually None or Even (must match the BMS master). You must enable supervisor control in the controller

If managing multiple independent Climaveneta units, use the BMS to sequence the units via their digital control registers ( 00001 ), evening out runtime hours across compressors.

The base W3000 controller typically has the necessary serial port for Modbus RTU. For connecting multiple units to a network or for IP-based communication, the FWS 3000 is the recommended solution. A dedicated "SERIAL CARD MODBUS TCP/IP" may also be an option depending on the unit's configuration.

: High-pressure (condenser) and low-pressure (evaporator) sensor values for troubleshooting thermodynamic efficiency.

Uses a 2-wire shielded twisted pair. Connect to terminals A (+), B (-), and GND. Default Settings:

: Read/Write Holding Registers (Analog configurations, setpoints)

: Indicates if the unit is actively enabled.
