Quick Summary
The HTW-WF02-16A WiFi Electric Underfloor Heating Thermostat is designed for electric floor heating systems used in residential and light commercial spaces. It provides a 16A line voltage output to control electric heating cables or heating mats. The thermostat measures room temperature through the internal sensor and can also work with an external floor sensor to regulate floor surface temperature.
This WiFi Electric Underfloor Heating Thermostat supports remote control through a mobile application. The interface offers clear temperature display and simple adjustment. This page explains the functional meaning of the thermostat, installation reference, technical parameters, possible project customisation and answers to typical project questions.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
(01) 16A electric floor heating load control
The WiFi Electric Underfloor Heating Thermostat provides a 16A switching output for electric heating cables or heating mats. This allows the thermostat to control the heating load directly without extra contactors in most residential installations.
(02) Dual sensor temperature monitoring
The thermostat supports both internal room sensing and external floor sensing. This configuration allows installers to regulate room temperature while limiting the maximum floor temperature, which helps protect flooring materials.
(03) Remote heating control through WiFi
The WiFi Electric Underfloor Heating Thermostat supports mobile application control. Users can monitor and adjust heating settings remotely. This function helps maintain comfort while allowing flexible temperature management when users are away. We have another standalone model without WiFi HTW-WF02-16A1.
(04) Clear display and user interface
A negative screen with white UI and white backlight provides clear visibility in various lighting conditions. The display shows temperature information and settings clearly, making everyday operation simple and reliable.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This WiFi Electric Underfloor Heating Thermostat is designed for electric floor heating systems in residential buildings, apartments and small commercial spaces. It controls electric heating cables or heating mats and works well in independent room heating applications. However, it is a standalone thermostat and therefore not suitable for projects requiring advanced building management system integration.
Despite these limits mentioned above, some ODM function customisation may be discussed according to project requirements. Possible options may include interface design changes, control logic adjustments or application features depending on project needs. All customisation requests normally require technical confirmation before production.
OEM cooperation is also supported for partners who wish to integrate the thermostat into their own product range. Options such as OEM logo printing, colour customisation, label design and packaging adjustments can usually be arranged according to project requirements.

Frequently Asked Questions
Q1. What heating systems can this WiFi Electric Underfloor Heating Thermostat control?
It is designed for electric floor heating cables or heating mats using line voltage switching.
Q2. Why does the WiFi Electric Underfloor Heating Thermostat use an external sensor?
The external sensor monitors floor temperature and helps prevent overheating, protecting flooring materials such as wood or laminate.
Q3. Can the WiFi Electric Underfloor Heating Thermostat work without WiFi?
Yes. The thermostat operates locally without WiFi, while the mobile application only provides remote control convenience.
Q4. What is the minimum order quantity and are samples available?
Samples are available. The usual MOQ is around 300 units, but smaller quantities can be discussed.
Q5. How can we place an order?
Please contact us first. After confirming requirements, we provide a proforma invoice. Payment methods include TT, PayPal, Visa and others.
Q6. How are the products normally shipped?
Courier door-to-door delivery usually takes about 7 days. Air freight is similar, while sea freight normally takes over one month.
