TC500-4TM-WH Schneider Room Thermostat for Four Pipe Fan Coil Units Modbus RTU White Auto Changeover
The TC500-4TM-WH is a four-pipe fan coil room thermostat from the Schneider Electric TC500 series, supplied in white and fitted with a Modbus RTU communication interface. The communication interface distinguishes it from standard four-pipe thermostats by making it an addressable point in a building management system. This enables facilities teams to monitor room temperature and setpoints, change operating modes, apply schedules, and detect unexpected thermostat states remotely.
Four-pipe terminals feature separate chilled and heating water circuits, requiring the thermostat to arbitrate between the two systems. The automatic mode with appropriate dead band maintains comfortable space conditions without valve hunting between circuits. Built-in temperature sensing eliminates the need for separate room sensors in most applications.
Specification Summary
Product type: Four-pipe fan coil room thermostat with communication
Order number: TC500-4TM-WH
Series: TC500 series
Pipe configuration: Four-pipe, separate chilled and heating water circuits
Communication: Modbus RTU for building management integration
Temperature sensing: Built-in room temperature sensor
Operating modes: Cooling, heating, automatic changeover and fan only
Fan control: Three fan speeds
Display: LCD showing room temperature, setpoint and mode
Housing colour: White
Mounting: Wall mounted, room side
Typical integration: Addressable point in a Modbus RTU supervisory system
Compliance: CE marking; RoHS and REACH declarations held by Schneider Electric
System Integration Notes
Proper documentation is critical for Modbus RTU network integration. The serial parameters, slave address, and register assignment must be recorded during commissioning and stored with as-built information. Key registers for fault detection should be mapped to trends from the outset.
For optimal performance, deliberately set the dead band between heating and cooling thresholds. A narrow band causes repeated changeover and actuator wear, while an over-wide band allows space temperature drift. Fan speed settings should be verified against room noise expectations.
Application Scenarios
Hotel Guest Rooms: Enables front desk and engineering teams to monitor and control room conditions without disturbing guests.
Office Buildings: Ideal for four-pipe perimeter terminals where building management systems report on energy and comfort, with automatic changeover handling transition seasons.
Healthcare Facilities: Applied in single rooms requiring individual control and remote supervision in hospitals and clinics.
Premium Residential: Specified for ducted fan coil systems where owners desire app-level visibility and control.
Portfolio Management: The Modbus interface transforms wall devices into reliable data sources for centralized maintenance and energy reporting across multiple buildings.
