Quick Summary
The HTW-WF06-16A3 Room Electric Heating Thermostat is designed for electric underfloor heating systems in homes and apartments. It controls heating cables through L and N output terminals. The thermostat supports WiFi connection and stable temperature regulation for daily indoor heating control and efficient room comfort.
This page explains how the Room Electric Heating Thermostat operates in electric heating installations. It introduces the control logic, wiring reference, and technical specifications. Installation notes and safety considerations are also included. OEM and ODM options for the Room Electric Heating Thermostat may also be discussed for project applications.

Key Features
(The core control functions and their practical value in heating systems.)
1. Electric Underfloor Heating Output
The Room Electric Heating Thermostat provides a 16A switching output for electric underfloor heating systems. L and N line voltage terminals allow direct control of heating cables. This configuration supports common residential electric heating installations.
2. WiFi Smart Temperature Control
The Room Electric Heating Thermostat supports WiFi communication through a mobile application. Users can adjust temperature settings remotely. Remote control improves daily heating management and increases convenience in modern households.(If looking for standalone version, check here)
3. Programmable Heating Schedule
The thermostat allows several programmable heating periods during the day. Users can set different temperature levels for different time periods. This scheduling helps maintain comfort while reducing unnecessary heating energy consumption.
4. Energy Saving Mode
Energy saving mode reduces heating demand during inactive periods. The Room Electric Heating Thermostat maintains a lower temperature automatically. This feature helps improve overall heating efficiency and reduces energy usage.
5. External Floor Sensor Protection
The thermostat supports connection with an external temperature sensor. The sensor monitors floor temperature continuously. This protection prevents overheating and helps protect floor materials during electric heating operation.

Project Fit & Customization
(Where the product can be used, its limits, and OEM/ODM possibilities.)
This Room Electric Heating Thermostat is designed for electric underfloor heating systems in residential buildings. It provides stable temperature control and reliable heating switching performance. The thermostat is not suitable for water valve control heating systems.
ODM cooperation can be discussed for projects requiring modified control logic or interface layout. Our engineers normally review system requirements before confirming suitable configurations.
OEM customisation is supported. Logo printing on the thermostat panel can be arranged. Labels and packaging design can also be customised. These options help the Room Electric Heating Thermostat match different branding projects.
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.)
