Quick Summary
The HTW-WF02-16A1 Electric Underfloor Heating Thermostat is designed for indoor electric floor heating systems. It provides a 16A line voltage output to control electric heating cables or heating mats. The thermostat measures room temperature through an internal sensor and can also work with an external floor sensor. This dual-sensor arrangement helps maintain stable floor temperature and protects the heating system from overheating.
This page explains the practical control logic and installation reference for the Electric Underfloor Heating Thermostat. It includes the functional meaning of key features, wiring reference, technical parameters and possible project customisation. Typical project questions and answers are also provided to assist system selection and deployment.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
(01) 16A direct electric heating control
The Electric Underfloor Heating Thermostat provides a 16A line voltage output designed for electric floor heating cables or heating mats. This allows direct switching of the heating load without additional relays, simplifying installation and reducing wiring complexity in residential heating projects. We have another model HTW-WF02-16A with WiFi function.
(02) Dual temperature sensing
The thermostat supports both internal room sensing and external floor sensing. Installers can choose the most suitable control method for the project. The external sensor is often used to protect floor materials from overheating while keeping the room temperature stable.
(03) Stable electric heating regulation
The Electric Underfloor Heating Thermostat continuously monitors temperature changes and switches the heating output accordingly. This simple but reliable control logic ensures stable room comfort and prevents frequent switching that may shorten system lifespan.
(04) Clear user interface for daily use
A negative screen with white UI and white backlight provides a clear display under different lighting conditions. This helps users read temperature values easily and adjust settings without confusion during normal daily operation.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This Electric Underfloor Heating Thermostat is designed mainly for residential electric heating systems using heating cables or heating mats. It is suitable for homes, apartments and small commercial rooms requiring independent heating control. However, it is a standalone thermostat and therefore not intended for projects requiring advanced building management system integration or centralised HVAC automation.
Despite these limits mentioned above, some ODM function customisation may be discussed according to project requirements. Possible adjustments can include control logic changes, display interface design or additional sensing configurations. These options depend on technical feasibility and project scale and normally require engineering confirmation before production.
OEM cooperation is also supported. Services such as OEM logo printing, colour customisation, product labels and packaging design can be arranged according to customer requirements. This helps distributors and HVAC solution providers integrate the thermostat into their own product portfolios.

Frequently Asked Questions
Q1. What heating systems can this Electric Underfloor Heating Thermostat control?
It is designed for electric floor heating cables or heating mats that require line voltage switching.
Q2. Why does the Electric Underfloor Heating Thermostat support an external sensor?
The external sensor can monitor floor temperature and prevent overheating, useful when protecting wood or laminate flooring materials.
Q3. Is the Electric Underfloor Heating Thermostat suitable for large HVAC systems?
No. It is mainly designed for standalone room heating control rather than large building management systems.
Q4. What is the minimum order quantity and are samples available?
Samples are available. The usual MOQ is around 300 units, but smaller quantities may be discussed for testing.
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.
