Quick Summary
HTW-HT03P-16A3 is a wi-fi thermostat for electric heating floor systems. It controls electric underfloor heating with a 16A output. The unit supports different load levels for various heating sizes. It also uses a floor sensor to prevent overheating and improve safety.
This page explains how the wi-fi thermostat works in electric heating systems. It also shows wiring, key parameters, and installation details. You will find notes on customisation and project limits for reference. Common questions are included to help with selection and daily use.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the electric heating system.)
(01) Electric underfloor heating control
This wi-fi thermostat controls electric heating cables or mats directly. It switches heating based on room temperature and setpoint. This helps keep a steady floor temperature and avoids sudden changes in electric heating use.
(02) Load selection levels
The controller offers three load levels for different heating sizes. Installers can match the load during setup. This helps avoid mismatch and keeps the system working safely under different electric heating conditions.
(03) Wi-Fi app control
The wi-fi thermostat connects to a mobile app for remote control. Users can adjust temperature and set schedules from anywhere. It also supports group control, which is useful for managing multiple rooms.
If this Wi-Fi feature is not required, one may refer to this standalone type instead (click → HTW-HT03P-16A1)
(04) External floor sensor protection
An external sensor checks the floor temperature directly. It helps stop overheating when the surface gets too warm. This is useful for wooden floors or materials that need temperature limits.
(05) Anti-frozen function
The wi-fi thermostat starts heating when the temperature drops near 5°C. It protects the space during empty periods. This helps prevent damage in buildings that are not always occupied.

Project Fit & Customization
(This section describes project suitability, system limitations, and available customization options.)
This wi-fi thermostat is not suitable for high power industrial heating loads. It does not support central BMS systems like Modbus or BACnet. It works as a standalone controller with app control, not for complex building systems.
Despite these limits mentioned above, some functions can be adjusted. Communication method, control logic, or sensor setup can be discussed. All changes depend on project size and need technical review before confirmation.
OEM options are also available for project use. Logo printing, housing colour, and labels can be customised. Packaging and simple interface changes can also be arranged based on project needs.
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.)
Frequently Asked Questions
Q1. Can this wi-fi thermostat be used for all heating systems?
This model is designed for electric underfloor heating systems only. It does not support water heating or boiler systems. Different models are available for those heating types.
Q2. How does the external sensor improve control?
The floor sensor measures real surface temperature. It helps avoid overheating beyond safe limits. This is important for comfort and floor protection.
Q3. Does the wi-fi thermostat support central control systems?
It does not support BMS systems like Modbus or BACnet. However, the app allows group control of multiple units. This is useful for managing several rooms together.
Q4. How to choose the correct model for heating type?
Different models match different heating systems. 16A is for electric heating, 3A for water systems. NV type is used for boiler heating control.
Q5. What is the minimum order quantity and can I get samples?
Samples are available for testing and checking. Standard MOQ is about 300 units. Smaller trial orders like 100 units can be discussed.
Q6. How to place an order and arrange shipment?
Contact us to confirm your requirements first. We will provide a PI for payment. Payment methods include TT, PayPal, and Visa, with EXW, FOB, or DAP terms.
Q7. How long does it take to prepare the products?
Standard samples can be shipped within 7 days. Custom orders need time for review and setup. Around 300 units usually take about one month.
Q8. What shipping methods are available?
Express delivery takes about 7 days to your door. Air freight is also around one week. Sea shipping takes over one month, depending on location.
