Quick Summary
The HTW-WF11-FC-2 is a room thermostat for 2-pipe fan coil unit systems with three-speed fan control and on/off valve output. It is suitable for AC-powered FCU installations where local wall control is required for room temperature, fan speed, cooling, and heating operation.
This room thermostat supports real-time display, scheduled programming, energy-saving mode, keypad lock, and stable daily control. It is a practical choice for hotels, apartments, offices, classrooms, and light commercial rooms that need simple FCU control without BMS, WiFi, EC fan, or 0–10V valve control.
Key Functional Highlights
(01) Direct 3-Speed Fan and Valve Control
This room thermostat provides relay outputs for low, medium, and high fan speeds, together with an on/off valve output. It can directly control standard AC fan coil units without an extra controller in many basic FCU projects. This helps simplify wiring, reduce system cost, and make installation easier.
(02) Real-Time Display
The built-in time display helps users and installers check the current system time clearly. This is useful when schedule control is used, because the room thermostat needs the correct time setting to run programmed operation properly.
(03) Programmable Temperature Control Logic
The programming function allows temperature set points to change automatically according to time schedules. In offices, apartments, and hotel rooms, this helps match operation with occupancy and reduce unnecessary fan and valve operation during low-use periods.
(04) Energy-Saving Operating Mode
The energy-saving mode adjusts the temperature target within a controlled range. It helps reduce extreme user settings and supports lower operating cost in projects where many room thermostats are installed across different rooms.
(05) Key Lock for Operational Stability
The key lock function helps protect project settings after installation. In hotels, apartments, classrooms, and managed buildings, it can reduce user misoperation and lower after-sales service pressure.
If one also requires an external sensor function, one may refer to this fan coil thermostat, HTW-WF11-FC-2E, instead.

Before selecting this model, the project should first confirm the FCU system type. This room thermostat is designed for 2-pipe fan coil units with three-speed fan motors and on/off water valves. It is not suitable for EC fan, 0–10V valve, 4-pipe valve control, or BMS communication projects.
Wiring
Wiring should be checked before installation. The installer should confirm power input, fan speed terminals, valve output, and relay load. Wrong fan speed wiring may cause unstable airflow, incorrect operation, or extra commissioning time.
Project Fit & Customisation
This room thermostat is suitable for local FCU control in hotel rooms, apartments, office rooms, meeting rooms, classrooms, and small commercial spaces. It is best used when the project needs a simple wall-mounted room thermostat instead of centralised control.
It is not suitable for projects that require BMS integration, network communication, centralized monitoring, EC fan control, WiFi app control, or modulating valve output. If these functions are required, we recommend checking another thermostat platform before order confirmation.
OEM options are supported, including logo printing, colour customisation, label customisation, model code adjustment, packaging design, manual adjustment, barcode label, product photo support, and datasheet support. Some ODM function customization can also be discussed based on project quantity, technical feasibility, and testing requirements.
Certificates and Compliance
This thermostat complies with European market requirements and is supported by certificates and test reports such as CE, RoHS, LVD, and EMC. For importers, distributors, OEM buyers, and project contractors, these documents can support market review, product filing, and customer communication.
Exhibition Moments
Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey. These exhibitions help us communicate with HVAC contractors, wholesalers, OEM customers, and project buyers from different markets.
Frequently Asked Questions
Q1: What type of FCU system is this room thermostat designed for?
It is designed for AC fan coil units with three-speed fan motors and 2-pipe systems using on/off water valves. If the project uses a 4-pipe system, EC fan, or 0–10V valve, another model should be selected.
Q2: Can this room thermostat control EC fans or modulating valves?
No. This model uses relay outputs for fixed fan speeds and on/off valve control. It does not provide 0–10V, PWM, or other modulating control signals.
Q3: Does this model support BMS communication such as Modbus or BACnet?
No. This is a standalone room thermostat for local FCU control. If the project needs Modbus, BACnet, gateway connection, or centralized monitoring, please contact us to confirm a suitable BMS thermostat model.
Q4: Can the thermostat settings or appearance be customized?
Yes. OEM customization can include logo, panel marking, label, model code, packaging, manual, default parameters, barcode, product photo, and datasheet. Function-level changes may also be discussed when the project quantity and technical conditions are suitable.
Q5: What is the minimum order quantity, and are samples available?
Samples are supported for testing and project confirmation. The typical MOQ is 300 units. Smaller trial quantities, such as 100 units, can also be discussed depending on stock status and customization requirements.
Q6: How can we place an order and make payment?
Please contact us with your system type, voltage, quantity, customization needs, and destination country. After confirming the details, we will provide a proforma invoice. We support T/T, PayPal, Visa, and trade terms such as EXW, FOB, and DAP.
Q7: How long does it take to prepare the products?
Non-customized samples are usually ready to ship within 7 days. Customized projects usually take around 3 to 5 weeks, depending on quantity, logo details, program adjustment, and testing needs. A 300-unit batch usually needs about one month.
Q8: How will the goods be shipped?
For samples and small orders, we usually recommend express door-to-door delivery by FedEx, DHL, UPS, or similar couriers, usually around 7 days. Air freight is also possible. Sea freight is better for larger orders and normally takes more than one month.
Final Note
This room thermostat is a practical choice for standard 2-pipe FCU projects. Before ordering, please confirm the fan type, valve type, voltage, wiring box, and control needs. If you need OEM support or another function, please feel free to contact us for model selection.
