Quick Summary
The HTW-WF01-16A3 Wifi Underfloor Heating Thermostat is designed 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 during daily use.
This page explains how the Wifi Underfloor Heating Thermostat works in real projects. It covers control meaning, wiring reference, and key parameters. It also explains model code logic and common questions. OEM and ODM options for the Wifi Underfloor Heating Thermostat are also briefly introduced for project discussion.
Key Features
(The core control functions and their practical value)
1. Direct Heating Output Control
This Wifi Underfloor Heating Thermostat provides direct 16A switching control. L and N terminals feed line voltage to heating cables. This structure suits many standard electric floor heating layouts.
2. WiFi Remote Operation
Built-in WiFi links the thermostat with a mobile application. Users can adjust temperature settings away from home. This makes daily heating control easier for houses, flats, and rental spaces.(If you don’t need Wifi, click here directly)
3. Programmable Heating Schedule
The thermostat supports timed temperature settings through the day. Users can set different periods for comfort and setback. This helps reduce unnecessary heating use while keeping rooms comfortable.
4. Floor Temperature Protection
An external floor sensor can be connected for extra protection. The sensor checks floor temperature during heating operation. This helps prevent overheating and protects floor finishes in normal 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 Wifi Underfloor Heating Thermostat is not suitable for water heating systems. It is also not suitable for boiler control with dry contact output. Projects needing Modbus communication should choose another version. Wet rooms, outdoor areas, and heavy industrial sites also need other thermostat types. Loads above the rated level require stronger control devices.
Despite these limits mentioned above, some ODM discussion is still possible. Communication type, screen logic, or control behaviour may be adjusted for some projects. Our engineers first review wiring, heating load, and application needs. Then we suggest practical options that can be developed and tested. This keeps the final solution more suitable for actual 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 Wifi Underfloor Heating Thermostat fit different brand plans, market channels, and project requirements.
Certificates 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 Wifi Underfloor Heating Thermostat control?
It is made for electric floor heating systems. The thermostat switches heating cables directly through L and N line voltage output terminals.
Q2. Can users control it remotely through WiFi?
Yes. The thermostat connects to a mobile application. Users can adjust temperature settings remotely and manage heating more easily in daily 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.
