SXWTRC3500B11X Schneider TRC Touchscreen Fan Coil BACnet MSTP PIR White

The Schneider Electric SXWTRC3500B11X is a SpaceLogic Touchscreen Room Controller (TRC) for low-voltage fan coil unit (FCU) and zone HVAC applications. This premium white fascia controller features a modern high-resolution 4.3-inch capacitive touchscreen, BACnet MS/TP and Modbus RTU dual protocol support, integrated RH sensor, and built-in PIR occupancy sensor.

• 4.3-inch high-resolution capacitive touchscreen with smartphone-like user experience
• 17 total I/O points (8 universal inputs, 4 universal outputs, 5 digital outputs)
• Highest I/O density of any Schneider fan coil room controller
• Dual protocol support: BACnet MS/TP and Modbus RTU
• Integrated PIR occupancy sensor and RH sensor
• BACnet BTL listed with CE, UL, and ICES-003 certifications
• 24 V AC/DC supply voltage with 0–10 V DC analog output

The SXWTRC3500B11X serves as the TRC series flagship for fan coil HVAC control. In premium hotel refurbishment projects, the 4.3-inch touchscreen provides a guest-facing interface that matches modern in-room technology expectations. In commercial office fit-outs, the 17 I/O configuration supports simultaneous control of 3-speed fan, 2-pipe or 4-pipe FCU valves, electric heating element, window contact override, and occupancy setback — all within a single controller.

BACnet MS/TP and Modbus RTU dual protocol support ensures compatibility with virtually every major BMS brand on the market, eliminating protocol gateway costs. The integrated PIR sensor enables LEED EQ credit compliance for occupancy-responsive HVAC without additional sensor wiring.
