Tender text

For connecting Wilo-Smart-SC/SCe-HVAC systems, Wilo-Smart-SC/SCe-Booster and Wilo-SiBoost Smart with Modbus RTU networks.

The Modbus RTU communications module represents a software extension to the integration of an SC/SCe system as Modbus Slave in an already existing bus system of the building management system. The connection is made via an RS485 interface. The settings with respect to the interface configuration can be made on the display of the SC/SCe system. Certain parameters can be written and read via Modbus, e.g. switchgear data, status and mode of the pumps, current actual value, setpoints, current speed of the pumps, recorded temperatures, operating hours, switching cycles, etc.

A retroactive activation of the "Modbus RTU" function in the switchgear is possible. Execution by Wilo Customer Service is recommended.
