Commonly used for Chiller temperature setpoint (Software CA13+). Assignable from 001 to 200 (Default is often 11). Best Practices for a "Patched" Installation

(codes 2, 3, 10, 11) are often due to physical layer faults or parameter mismatches rather than software bugs.

A writeable coil used to clear non-critical, latched faults remotely once the root cause is resolved. 3. Analog Inputs (Read-Only Input Registers)

Place a 120-ohm resistor across the 'A' and 'B' lines at the physical end of your daisy chain to eliminate signal reflections. Default Serial Parameters:

Do you need the for a specific model (e.g., NX or FOCS)? If you want, I can: Commonly used for

Climaveneta software is protected and proprietary . Unauthorized "patches" can void warranties or lead to system failures.

Set to a minimum of 3.5 characters (approximately 4ms at 9600 bps) to prevent overlapping transmission packets.

Based on standard Climaveneta W3000 documentation, here is the essential information related to this configuration: This public link is valid for 7 days

Implement a patch or configuration change to increase the internal communication buffer turnaround time. Set the BMS polling interval to a conservative minimum of 1000ms to 2000ms per node . Data Type Misalignment (The 32-bit Swap)

Locate the RS485 terminal block on the auxiliary communication card (often labeled + , - , and GND or A , B , and Ref ).

The W3000 controller utilizes the Modbus RTU protocol (RS485) to communicate with external monitoring systems. In a standard setup, the controller acts as a slave, providing registers that report temperature, pressure, compressor status, and alarm codes.

Climaveneta W3000, W3000 SE, and W3000 Large controllers manage chillers, heat pumps, and precision cooling units. They interface with external automation systems via serial or ethernet networks. Hardware Interface
