Quick Summary
This hotel thermostat HTW-WF11-FC-2KN is designed for typical fan coil room control. It manages a 3-speed fan and a two-pipe on/off valve. The controller supports heating and cooling operations in FCU systems. Door card input enables energy saving when the guest leaves the room.
This page explains the control logic, functions, and engineering parameters of this model. It also clarifies the wiring reference and model code meaning. Common installation questions and project considerations are included. Project teams may also discuss possible configuration or OEM options.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
(1) Stable 3-speed fan control
Three fan speeds allow the controller to match airflow demand under different loads. This improves comfort stability. Maintenance teams also benefit from simple relay-based fan control with reliable long-term operation.
(2) Practical two-pipe valve control
The thermostat switches an on/off valve in typical two-pipe FCU systems. The control logic is clear and predictable. This reduces commissioning time and helps technicians troubleshoot easily during project operation.
(3) Door card energy management
The door card input allows the hotel thermostat to detect room occupancy status. When the guest removes the card, the system can reduce operation. This supports hotel energy management and prevents unnecessary fan coil running.
(4) Modbus communication for BMS
RS485 Modbus communication enables integration with a building management system. Facility teams can monitor room temperature and operating status remotely. This improves central supervision and simplifies maintenance in large hotel projects.
If the BACnet protocol is preferred instead of Modbus, the corresponding model is (HTW-WF11-FC-KB).

Code Guide
(This section explains what configuration the model code refers to.)
| Fan coil series | xx stands for |
| EC | EC fan |
| 2/4 | 2 for 2-pipe on/off; 4 for 4-pipe on/off system |
| M | Modulating valve control |
| W | Wi-Fi |
| N/B | N for Modbus; B for BACnet |
| K/E | K for Keycard; E for External sensor |
| 24 | Powered by 24V, or with 24V output for 0-10V valve |
| Example HTW-WF11-FC-xx: if xx = 2EN, it stands for a 3-speed fan, 2-pipe system with on/off valve control, external sensor function, and Modbus communication. Most sub-models are ready-made. Kindly contact us to confirm availability. | |
Project Fit & Customisation
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This hotel thermostat is not suitable for systems requiring variable fan control. It also cannot operate modulating valves or EC fan motors. Projects requiring wireless control, cloud management, or mobile applications should consider other controller types.
Despite these limits mentioned above, certain configuration adjustments can still be discussed. ODM options may include communication settings, control logic adjustment, or sensor configuration. These changes depend on project scale and engineering evaluation.
OEM cooperation is also available for branding requirements. Typical requests include logo printing, colour changes, and customised labels. Packaging design and product marking can also be adjusted for distributor or project branding.

Frequently Asked Questions
1. Can this hotel thermostat work with all FCU systems?
This model is designed for two-pipe fan coil systems using on/off valves. Other systems such as modulating valves or EC fans require different thermostat models.
2. Does the door card input control the whole air-conditioning system?
The door card signal only affects the thermostat operating status. It allows the controller to reduce operation when the guest leaves the room.
3. Can this thermostat connect to a building management system?
Yes, the thermostat supports RS485 communication using the Modbus protocol. This allows facility teams to monitor operating status through the central BMS system.
4. What is the minimum order quantity and are samples available?
Samples are available for testing before bulk orders. The typical minimum order quantity is around 300 units, although smaller quantities can sometimes be discussed.
5. How can we place an order?
Please contact our team to confirm your project requirements first. After confirmation, we will issue a proforma invoice. Payment methods include TT, PayPal, Visa and similar options.
6. How are the thermostats usually shipped?
Courier delivery to the project site is commonly recommended and takes about seven days. Air freight also takes around seven days, while sea shipping usually requires one month or longer.
