FCU Control
FCU Thermostat Selection Guide for Hotels and Offices
Learn how to choose fan coil thermostats for 2-pipe, 4-pipe, valve control, 0-10V fan output and hotel or office HVAC projects.
Start With The Fan Coil System Type
FCU thermostat selection depends on whether the project uses 2-pipe or 4-pipe fan coil units, two-line valve or three-line valve control, and whether the fan requires relay speed control or 0-10V output.
Choose Protocol And Control Output
Hotel and office projects may need WiFi, Zigbee, Modbus, 0-10V fan output or valve output. These requirements should be confirmed before panel selection because the same front design can represent different control versions.
Use Wiring Diagrams For Installer Confidence
Clear wiring diagrams help installers understand valve, fan and power connections. For SEO and buyer trust, the product page should show typical wiring diagrams without overloading the page with repeated images.
