Product Description
TC500-4T-WH Schneider TC500 Series Fan Coil Thermostat
Four-pipe configuration with white LCD display, 3 fan speeds, and Modbus communication option
Product Overview
The TC500-4T-WH is the four-pipe version of the Schneider Electric TC500 fan coil thermostat, finished in white for interiors where the wall plate is expected to blend into light surfaces. Four-pipe terminals carry separate chilled and heating water circuits, requiring the thermostat to arbitrate between cooling and heating rather than simply switching a single coil.
The liquid crystal display presents room temperature and setpoint, while users can select cooling, heating, automatic, or fan-only operation with three discrete fan speeds. Automatic mode is particularly important in practice: on a four-pipe terminal with a dead band, the thermostat can maintain space temperature within a band without hunting between the two water circuits.
The communication variant is available for projects requiring terminal unit supervision from a central system, transforming local comfort devices into monitored points within the building management system.

System Integration Notes
The four-pipe sequence requires a dead band to be set during commissioning, as the distance between cooling and heating thresholds determines whether the terminal operates calmly or oscillates. Too narrow a band causes repeated valve changes, wearing actuators and disturbing occupants; too wide a band allows uncomfortable temperature drift before activation.
Fan speed selection should be reviewed against noise considerations. On four-pipe terminals, the fan typically runs continuously in automatic mode, so insufficient low-speed airflow across the coil may cause the thermostat to hold valves open unnecessarily.
For supervised variants, the register map should be documented in handover packages to enable head-end systems to read setpoint, room temperature, and valve state without reverse engineering the terminal.
Application Scenarios
Premium Hotel Suites: Four-pipe thermostats provide independent heating and cooling capability that two-pipe terminals cannot deliver, ideal for executive floors and luxury accommodations.
Open-Plan Offices: Perimeter fan coil units maintain stable temperatures in glass-line zones during transition seasons when some areas require cooling while others need heating.
Healthcare Facilities: Single patient rooms benefit from individual temperature control as part of the therapeutic environment in hospitals and clinics.
High-End Residential: White housing suits domestic interiors in ducted or fan coil systems for luxury residential projects.
Supervised Systems: Facilities teams choose the communication variant for terminal-level visibility in energy reporting and fault detection, replacing manual monthly inspections.
