The Climaveneta W3000 controller (and its variants like W3000+, W3000 Compact, and W3000 TE) uses the Modbus RTU protocol for communication with Building Management Systems (BMS). Communication Settings
To establish a connection, the supervisor parameters on the unit must be configured as follows: Protocol: Modbus. Communication Speed: Typically 9600 or 19200 baud. Unit ID: Adjustable from 001 to 200 (default is often 11).
Enables: Both "On/off enable" and "Operating mode enable" must be set to "Yes" in the supervisor menu to allow remote control. Hardware Connection (RS485)
Interface Card: Integration requires a dedicated Serial Card Modbus (e.g., code 4182) installed in the controller's BMS slot.
Wiring: Uses a 3-wire RS485 connection (GND, Tx/Rx+, Tx/Rx-). Cable: Twisted and shielded AWG 20/22 cable is recommended.
Termination: A 120-ohm resistor should be added in parallel to the last device in the chain to prevent signal reflection. Modbus Register Types
The W3000 uses standard Modbus function codes to access data:
Digital Data (Coils/Inputs): For unit status (On/Off), active alarms, and compressor status.
Analog Data (Holding/Input Registers): For sensor readings like water temperatures, pressures, and setpoint adjustments.
Note: Some values like surge thresholds or pressures may be scaled (e.g., divided by 10).

Here are the key technical features of the Climaveneta W3000 Modbus implementation:
Common register categories (example — confirm with your manual):
W3000 (RS-485) → Modbus RTU → Gateway (e.g., Anybus, Intesis) → BACnet/IP/MSTP → BMS
or
W3000 → Direct Modbus RTU → PLC/SCADA (with RS-485 port)
Always obtain the official Modbus register map for your exact Climaveneta unit model and W3000 firmware version. Using a wrong map can cause incorrect readings or unexpected unit behavior.
If you need help finding the register map or wiring diagram for a specific Climaveneta model (e.g., ERACS, FOCS, NX, i-Koax), provide the full model code.

Hi everyone,
I am currently trying to pull data from a Climaveneta W3000 chiller controller into a SCADA system via Modbus RTU.
I have the physical connection sorted (RS485 wiring verified), but I am struggling to find the correct register map. The manual provided by the installer covers mechanical specs but lacks the specific memory addresses for the variables (e.g., Leaving Water Temp, Compressor Status, Active Alarms).
Does anyone have a PDF of the Modbus register table for the W3000 series controllers? Or does anyone know the starting address range for the standard measurement values?
Thanks in advance for the help!
A passive Modbus connection is wasted potential. For true energy management, implement these features:
