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.
