-The newer S-series pump exposes a built-in TCP Modbus server that can be used to communicate with the pump. To enable support for this integration, the pump must be connected to your local network and network (5.2 - Network settings) and Modbus (7.5.9 - Modbus TCP/IP) must be enabled. More details on the Modbus support in the pump can be found in Nibe document [M12676EN](https://assetstore.nibe.se/hcms/v2.4/entity/document/34499/storage/MDM0NDk5LzAvbWFzdGVy).
