Quick Summary
The HTW-EB-FC-FC-2W WiFi Thermostat is designed for 2-pipe fan coil systems used in heating and cooling applications. It controls a 3-speed fan and motorised valve with clear logic. The WiFi Thermostat supports remote control through app connection, improving operation flexibility.
This page explains how the WiFi Thermostat works in FCU systems and what it means for daily use. It includes wiring reference, technical parameters, and model code explanation, followed by project fit guidance, customisation options, and common questions.
Key Features
(This section explains the core control functions and their practical value.)
(01) Remote control with WiFi connection
The WiFi Thermostat allows remote operation through mobile applications. This improves user control flexibility and supports better temperature management without needing direct access to the device.
(02) Stable 2-pipe system control
The WiFi Thermostat is designed for standard 2-pipe FCU systems. It manages heating and cooling through one valve, ensuring simple system logic and reliable performance. If you need thermostat for 4-pipe system with WiFi function, you can refer to this link: HTW-EB-FC-4W.
(03) 3-speed fan operation
The WiFi Thermostat provides manual or automatic fan speed control. This helps maintain comfort and supports efficient system operation in different room conditions.
(04) Clear display with backlight
The WiFi Thermostat features a negative black backlight interface. This improves readability and allows easy operation in both bright and low-light environments.

| 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 |
| Example | HTW-WF11-FC-xx: if xx = 2W, it stands for a 2-pipe system with on/off valve control and WiFi function. Most sub-models are ready-made. Kindly contact us to confirm availability. |
Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
The WiFi Thermostat is suitable for 2-pipe FCU systems where remote control is required. It is not suitable for projects requiring Modbus or BACnet integration with building management systems.
Despite these limits mentioned above, ODM customisation can be discussed. Functions such as communication protocols or interface adjustments may be considered based on project needs.
OEM customisation is also supported. This includes logo printing, colour options, and label design. It helps meet project standards and branding requirements.
