ShenZhen Toupwell Technology Co.,Ltd

FCU Thermostats for 2-Pipe and 4-Pipe HVAC Systems

Toupwell manufactures FCU thermostats for room-level heating and cooling in hotels, apartments, offices and commercial buildings. Our range includes on/off and 0–10V control models, with Modbus, BACnet, WiFi and Zigbee options for different project requirements.

Match your fan coil unit thermostat to the water system, fan motor, valve actuator and communication network. From standalone room control to connected building projects, we help HVAC distributors, equipment manufacturers and contractors select suitable configurations.

Our Thermostats Wholesale range also covers underfloor heating, boiler and low-voltage HVAC controls, supporting procurement across different system types.

Choose the Right Fan Coil Unit Thermostat

On/Off Fan Coil Control

On/off models switch compatible valve actuators and control the fan according to room temperature and operating settings. Select a configuration that matches the unit’s pipe arrangement, fan wiring and electrical load.

These thermostats suit projects requiring straightforward local operation without a building communication network.

0–10V Modulating Control

Our 0–10V modulating thermostats include configurations for modulating valves and EC fan motors. Variable control allows the output to adjust with room demand.

Fan and valve outputs must be checked separately. A thermostat with a 0–10V valve output does not automatically provide the same signal for fan speed control.

Modbus and BACnet Integration

For centralized HVAC management, Toupwell offers Modbus FCU thermostats and BACnet thermostat options.

Confirm the protocol version, available data points, network settings and controller requirements before ordering. Select the communication model specified for your building management system.

WiFi and Zigbee Options

Our WiFi fan coil unit thermostats provide app-based control on compatible versions. Zigbee models connect through a compatible gateway.

Choose the required platform and verify gateway compatibility during sample evaluation. WiFi, Zigbee, Modbus and BACnet are configuration choices rather than standard features on every model.

Technical Options for Project Selection

The following specifications summarize options shown in the TP501 series documentation. Confirm the exact configuration and wiring diagram for your selected model.

Electrical ratings, outputs and optional functions depend on the ordered version. Use the model-specific datasheet to verify compatibility.

Match the Thermostat to Your HVAC System

2-Pipe and 4-Pipe Applications

A 2-pipe fan coil uses a shared water circuit for heating or cooling. Confirm how the thermostat handles seasonal changeover and whether a sensor input or manual setting is required.

A 4-pipe system has separate heating and cooling circuits. Select a thermostat with the appropriate valve outputs and operating sequence.

Three-Speed and EC Fans

Traditional three-speed fans require compatible switched outputs. EC motors commonly use a variable control signal such as 0–10V.

Check the motor voltage, signal requirements and load rating. Matching the thermostat to the motor helps avoid incorrect speed operation and unnecessary installation changes.

Before Selecting a Model

● Identify the fan coil’s pipe arrangement and heating/cooling requirements.

● Confirm supply voltage, valve actuator type and control signal.

● Check fan motor type, current and wiring.

● Specify local control, app access or BMS integration.

● Confirm installation dimensions and any external sensor or keycard requirements.

Room Control for Hotels and Commercial Buildings

Hotel Rooms

Selected TP518 configurations support keycard inputs for room energy management. Combine suitable fan and valve control with agreed room settings to support guest comfort and hotel operating requirements.

Offices and Commercial Properties

Modbus or BACnet versions can support centralized monitoring and control where the selected thermostat’s communication functions match the building system.

Apartments and Residential Projects

Standalone, WiFi and Zigbee configurations provide different approaches to room control. Programmable schedules on selected models help align heating and cooling operation with occupancy patterns.

The right fan coil control solution depends on the equipment and control strategy. Energy savings vary with system design, settings and building use.

Manufacturing and OEM/ODM Support from Toupwell

Toupwell combines over 17 years of thermostat industry experience with standard product supply and customization for HVAC brands and project suppliers.

● Production processes include SMT, AOI inspection, DIP assembly and functional testing.

● Thermostats undergo 24 or 48 hours of aging testing according to product requirements.

● The company’s stated monthly supply capacity is 30,000–50,000 units across its product range.

● OEM options include logos, housing colours, packaging and localized manuals.

● ODM development can cover software, hardware, user interfaces and product structures.

● Two-year after-sales support is available from the purchase date, subject to the agreed service terms.

Our OEM/ODM thermostat services support both private-label products and application-specific development. Sample timing and development schedules are confirmed against the configuration and scope.

CE and RoHS documentation, together with other applicable compliance documents, should be confirmed for the selected model and destination market.

Frequently Asked Questions

Q1: What does an FCU thermostat control?

An FCU thermostat compares room temperature with the setpoint and controls compatible fan and valve outputs. The operating sequence depends on the system and selected configuration.

Q2: Can one model work with both 2-pipe and 4-pipe systems?

Selected Toupwell series offer both configurations. Confirm the exact version, output terminals and settings before installation.

Q3: Can your thermostats control EC fan motors?

Yes. Selected models provide 0–10V EC fan control. Specify this requirement separately from the valve control signal.

Q4: Do you offer thermostats for building management systems?

Yes. Modbus and BACnet options are available. Confirm protocol details and supported data points against the project’s integration requirements.

Q5: Can an existing thermostat be replaced directly?

Replacement requires checking the voltage, terminal functions, valve outputs, fan control and mounting dimensions. Share the existing model and wiring diagram for a compatibility review.

Q6: Can Toupwell supply private-label FCU thermostats?

Yes. Branding, packaging and selected functional changes are available. More extensive software, hardware or structural development can be evaluated through our ODM service.

Request an FCU Thermostat Recommendation

Send your fan coil specification, supply voltage, pipe arrangement, fan type, valve signal, communication requirements and order quantity.

For replacement projects, include the existing thermostat model and wiring diagram. For OEM orders, add your branding and functional requirements.
