Quick Summary
HTW-WF10-16A3MT is a Matter Protocol Electric Underfloor Heating Thermostat for electric floor heating systems. It controls heating output through relay switching and sensor feedback. The unit supports internal and external sensors for stable control. WiFi and Matter protocol enable remote access and system integration.
This page explains how the Matter Protocol Electric Underfloor Heating Thermostat works in projects. It covers control logic, wiring method, and parameter setup. It also explains configuration meaning and customisation options. Typical questions and answers are included for quick understanding.

Key Features
(This section explains the core control functions and their practical value.)
01 Relay-Based Heating Control
The Matter Protocol Electric Underfloor Heating Thermostat controls heating using relay output. It compares measured temperature with setpoint. This ensures stable heating operation and reduces unnecessary switching in daily use. We also have a standalone model HTW-WF10-16A1.
02 Internal and External Sensor Control
The thermostat supports both internal and external sensors for temperature detection. Internal sensor manages room temperature. External sensor limits floor temperature and protects heating system during continuous operation.
03 WiFi and Matter Connectivity
WiFi and Matter protocol enable remote control and system integration. Users can adjust settings through mobile application or smart platforms. This improves flexibility in smart home and project deployment scenarios.

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-WF10-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 Matter Protocol Electric Underfloor Heating Thermostat is not suitable for water or boiler systems. It does not support valve or fan coil control. It is not designed for complex BMS protocols like Modbus. It works only with electric heating loads.
Despite these limits mentioned above, ODM customisation can be discussed. Communication protocol or app functions may be adjusted. Control logic or sensor settings can be modified based on project needs. Final feasibility depends on technical evaluation.
OEM services are available for branding and appearance adjustments. Logo printing, colour customisation, and label design can be supported. Packaging and interface changes may also be arranged for bulk orders.
