Quick Summary
The HTW-WF06-16A1 Wired Electric Heating Thermostat is designed for electric underfloor heating systems in homes. It controls heating cables using L and N line voltage output terminals. The thermostat works with a 100–240 Vac power supply. Stable sensing helps maintain accurate room temperature.
This page explains how the Wired Electric Heating Thermostat works in electric floor heating installations. It introduces control functions, wiring references, and technical parameters. Installation notes and system safety considerations are also included. OEM and ODM possibilities for the Wired Electric Heating Thermostat may also be discussed.

Key Features
(This section explains the core control functions and their practical value.)
1. Electric Floor Heating Output
The Wired Electric Heating Thermostat provides a 16A switching output for electric underfloor heating systems. L and N line voltage terminals allow direct control of heating cables. This configuration supports typical electric floor heating installations in residential environments.(If water heating system is required, see this model)
2. Programmable Temperature Control
The thermostat allows several programmable heating periods each day. Users can set different temperature levels for different time periods. This helps maintain comfort while reducing unnecessary energy use.
3. Energy Saving Mode
Energy saving mode reduces heating demand during inactive hours. The Wired Electric Heating Thermostat automatically maintains a lower temperature setting. This approach improves energy efficiency while still protecting indoor comfort.
4. External Floor Sensor Protection
The thermostat supports connection to an external floor temperature sensor. The sensor monitors floor temperature continuously during heating operation. This protection prevents overheating and helps protect flooring materials.

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 / 2 / 3 | 1 = Standalone, 2 = Modbus, 3 = Wi-Fi |
| Example HTW-WF06-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
(Where the product can be used, its limits, and OEM/ODM options.)
This Wired Electric Heating Thermostat is designed for electric underfloor heating systems. It is not suitable for water heating systems that require valve control. Projects needing remote communication protocols should select another thermostat model.
Despite these limits mentioned above, ODM cooperation may still be discussed. Interface layout or control behaviour may be adjusted according to project needs. Our engineers review heating system requirements before confirming a suitable solution.
OEM customisation is also supported. Logo printing on the thermostat panel can be arranged. Product labels and packaging design can also be customised. These options help the Wired Electric Heating Thermostat match different branding projects.
Certifications
This thermostat complies with European market requirements and is supported by certifications such as CE, RoHS, LVD test reports, EMC test reports, etc

Exhibition Moments
Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.
