Quick Summary
The HTW-WF01-16A1 Electric Underfloor Heating Thermostat is made for electric floor heating systems. It controls heating loads through L and N line voltage output terminals. The thermostat works with a 100–240 Vac power supply. Built-in and external sensing help manage room and floor temperature safely.
This page explains how the Electric Underfloor Heating Thermostat works in practical projects. It shows control meaning, wiring reference, and key parameters. It also covers model code guidance and common questions. OEM and ODM options for the Electric Underfloor Heating Thermostat are also briefly introduced.
Key Features
(The core control functions and their practical value.)
1. Direct Heating Load Control
This Electric Underfloor Heating Thermostat provides a direct 16A switching output. L and N terminals connect line voltage to heating cables. This control method suits many standard electric floor heating layouts.(If you’re looking for Water heating system, click here)
2. Programmable Heating Schedule
The thermostat supports programmable temperature periods during the day. Users can set different temperatures for different time blocks. This helps keep comfort while reducing unnecessary heating use.
3. Energy Saving Mode
Energy saving mode lowers the target temperature during less active periods. This reduces heating demand without stopping normal control. It helps save energy in homes, flats, and similar spaces.
4. Floor Temperature Protection
The thermostat supports an external floor sensor for extra protection. The sensor checks floor temperature continuously during operation. This helps prevent overheating and protects floor finishes in daily use.

Model Code Guide
(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-WF01-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 Electric Underfloor Heating Thermostat is not suitable for water heating control. It is also not suitable for boiler systems using dry contact output. This model does not support Modbus communication or Wi-Fi connection. It cannot connect to app control platforms or BMS systems. Outdoor areas and wet zones also need other thermostat types. Projects above the rated electrical load should use stronger control devices.
Despite these limits mentioned above, some ODM discussion is still possible. Communication type or control logic may be adjusted for certain projects. Our engineers first review wiring, heating load, and application needs. Then we suggest practical options that can be developed and tested. This helps keep the final thermostat suitable for real installation work.
OEM customisation is also supported for normal project needs. We can discuss logo printing, front label changes, and package updates. Panel colour and carton details may also be adjusted. These options help the Electric Underfloor Heating Thermostat fit different brand plans and sales channels.
Certifications and Compliance
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.
Frequently Asked Questions
Q1. What systems can this Electric Underfloor Heating Thermostat control?
It is made for electric floor heating systems. The thermostat switches heating loads directly through L and N line voltage output terminals.
Q2. Does it support floor temperature protection?
Yes. An external sensor can monitor floor temperature during operation. This helps limit overheating and protects floor materials in daily heating use.
Q3. Is it suitable for standard wall box installation?
Yes. The thermostat fits 86×86 mm junction boxes and EU round boxes. These box types are common in many indoor heating projects.
Q4. What is the minimum order quantity and are samples available?
Samples are available for checking. The usual minimum order quantity is 300 pieces, but smaller trial quantities can also be discussed.
Q5. How can we place an order?
Please contact us first. After requirement confirmation, we provide a proforma invoice. Payment supports TT, Paypal, Visa, and more. Terms include EXW, FOB, DAP and more.
Q6. How are the products usually shipped?
Express door-to-door delivery is usually recommended and takes about seven days. Air shipping is similar. Sea shipping normally takes over one month.
