SE8350U0B11 Schneider SE8000 Low Voltage Fan Coil and Zone Room Controller BACnet MS/TP RH Sensor White
The SE8350U0B11 is a low-voltage fan coil room and zone controller from the Schneider Electric SE8000 range, designed to bridge the gap between mechanical thermostats and full building management systems.
Product Overview
This unit integrates a room temperature sensor, relative humidity sensor, fan coil terminal control sequence, and communication interface within a single white wall-mounted case. Unlike basic thermostats, it actively measures and regulates humidity, making it ideal for climates and spaces where latent load affects comfort. The controller supports both BACnet MS/TP and Modbus RTU protocols, with firmware updates available via USB using the SE8000 uploader tool.

System Integration
The controller features a two-part installation design: the base handles field wiring for valves, actuators, fan speed relays, and changeover sensors, while the front section contains sensing and display components. Commissioning begins with wiring configuration, and proper network parameter setup is crucial for BACnet MS/TP or Modbus integration. Password and lock level settings should be established during handover to maintain energy strategy integrity.
