Quick Summary
The HTW-WF03-16A3 Tuya electric heating thermostat is designed with 16A load control. It is used for electric floor heating systems in daily use. The colourful LED display is easy to read. An external sensor helps limit floor temperature and prevents overheating.
This page helps you understand how this Tuya electric heating thermostat works in real use. It explains control logic, wiring, and key settings. It also shows how it fits different projects. Simple guidance is included to support installation and daily use.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the specific HVAC system.)
01 — Colourful LED display with adjustable brightness
The screen shows temperature and working status clearly. Brightness can be adjusted for day and night use. It helps avoid glare in dark rooms. This makes daily operation more comfortable and easy to follow.
02 — 16A load control for electric heating systems
This Tuya electric heating thermostat supports up to 16A load. It can control most electric floor heating systems directly. Extra relays are not needed in many cases. This helps keep wiring simple and stable.
If a water heating thermostat is required instead, one may refer to this model (please click → HTW-WF03-3A3).
03 — External sensor with floor temperature limit protection
The external sensor checks the floor temperature during heating. It works with control logic to prevent overheating. This is useful for wood or sensitive flooring. It helps keep the system safe during long use.
04 — Weekly programmable control logic
The weekly schedule lets you set different temperatures through the day. Heating follows daily routines more closely. This helps reduce energy use when heating is not needed. The system becomes easier to manage.
05 — Tuya app control and group management
Tuya WiFi allows remote control through a mobile app. You can adjust settings without going to the room. Group control lets several thermostats work together. This is useful for flats or small projects.

Project Fit & Customisation
(This section describes project suitability, system limitations, and available customization options.)
This Tuya electric heating thermostat is not suitable for water or boiler systems. It does not support valve control or low current outputs. It is not made for outdoor or high humidity spaces. Power supply must stay stable for proper operation.
Despite these limits mentioned above, we can discuss some function changes. Control logic or communication options may be adjusted if needed. We suggest confirming project details early. Final solutions depend on actual use and quantity.
OEM options are also available for project needs. Logo printing, colour changes, and label updates can be arranged. Packaging can also be adjusted if required. This helps match your brand and project style.
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: Can this thermostat be used for water heating systems?
This model is for electric floor heating only. It does not control water valves. For water systems, a 3A model is required.
