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.
: The temperature of the supply water leaving the chiller.
The marriage of the Climaveneta W3000 and Modbus yields concrete operational advantages: climaveneta w3000 modbus
A baud rate of 9600 is most commonly used and is the factory default setting. This provides a good balance of speed and reliability for most building automation applications.
: Used to adjust operating setpoints (e.g., Chilled Water Setpoint). Data Mapping and Register Architecture You must enable supervisor control in the controller
The is a chiller/heat pump controller family. Its Modbus feature allows integration with BMS (Building Management Systems) like BACnet via gateway, or direct RTU communication.
The core of any Modbus integration is mapping the internal variables of the controller to standard Modbus registers. Climaveneta structures its memory map using standard function codes, dividing data into binary (digital) and analog formats. Common Modbus Function Codes Used: Serial Settings : Protocol : Modbus
Climaveneta provides extensive documentation for the W3000 series:
