Key Features
(This section explains the core control functions and their practical value.)
01 Wireless control architecture
This WiFi Wireless Heating Thermostat uses a separate panel and receiver structure. It avoids direct wiring between control point and heating equipment. This simplifies installation and improves flexibility in both new and retrofit projects. If you are interested in thermostats for boiler heating, you can refer to this link: HTW-WKT18-NV3.
02 WiFi remote control function
The WiFi Wireless Heating Thermostat connects to mobile applications through WiFi. It allows remote temperature adjustment and monitoring. This helps manage heating systems more efficiently across different rooms or zones.
03 Internal temperature sensing
The WiFi Wireless Heating Thermostat uses a built-in NTC sensor for temperature measurement. It provides stable and consistent readings for control logic. This ensures reliable heating response in daily operation.
04 Stable relay output control
The receiver provides relay output for water heating and boiler systems. It supports stable switching under normal load conditions. This improves system reliability and reduces operational issues.
Product Design and Display
(This section shows the product’s dimensions and the interface layout.)
The thermostat features a modern LED display with capacitive touch buttons. The panel uses a clean design suitable for indoor environments. The receiver is wall-mounted and compact. The overall structure supports easy installation and daily operation.

Model Code Guide
(This section explains what configuration the model code refers to.)
| Heating series | xx stands for |
|---|---|
| 3A | Water Heating, with NC+NO+COM output terminals |
| 16A | Electric Underfloor Heating, with L+N line voltage output terminals + External Sensor |
| NV | Boiler Heating, with Non-Voltage Dry Contact |
| 1/3 | 1 = Standalone, 3 = Wi-Fi |
| Example HTW-WF11-xx: if xx = 16A3, it stands for electric floor heating with external sensor support and Wi-Fi 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.)
This WiFi Wireless Heating Thermostat is not suitable for systems requiring wired control signals. It does not support BMS protocols such as Modbus or BACnet. It is also not suitable for projects needing external temperature sensing.
Despite these limits mentioned above, ODM customisation can be discussed. Control logic and communication settings may be adjusted. Interface and functional changes can be evaluated. Final solutions depend on technical feasibility.
OEM customisation is supported for branding and appearance. This includes logo printing, colour options, and packaging design. Label and interface changes can also be discussed. These options help adapt the product to different markets.
