Quick Summary
HTW-HT09B-16A3 is an WiFi Electrical Underfloor Heating Thermostat for electric floor heating systems. It controls heating output using relay switching and sensor feedback. The unit supports internal and external sensors for stable control. WiFi enables remote adjustment through mobile application for flexible operation.
This page explains how the WiFi Electrical Underfloor Heating Thermostat works in projects. It covers control logic, wiring method, and parameter setup. It also explains model configuration and customisation options. Typical questions and answers are included for quick reference.
Key Features
(This section explains the core control functions and their practical value.)
01 Relay-Based Heating Control
The WiFi Electrical Underfloor Heating Thermostat controls heating through relay switching. It compares measured temperature with setpoint. This ensures stable heating output and avoids frequent switching during daily operation.
02 Dual Sensor Temperature Control
The WiFi Electrical Underfloor Heating Thermostat supports both internal and external sensors for temperature detection. Internal sensor manages room temperature. External sensor protects floor surface and limits overheating during continuous heating operation.
03 WiFi Remote Operation
WiFi allows remote control through mobile application for temperature adjustment. Users can manage settings without direct access. This improves flexibility in daily use and simplifies control in multi-room projects. We have another standalone model HTW-HT09B-16A1.

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 |
| 3 | 3 = Wi-Fi |
| Example HTW-HT09B-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 Electrical 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 method or app functions may be adjusted. Control logic or sensor settings can be adapted based on project needs. Final solution depends on technical evaluation.
OEM services are available for branding and appearance changes. Logo printing, colour options, and label design can be supported. Packaging and interface adjustments may also be arranged for bulk projects.
