Quick Summary
HTW-ECB6-16AB is a WiFi electric underfloor heating thermostat designed for electric floor heating systems. It switches heating loads using L and N line voltage output terminals. Internal and external sensors measure temperature for stable heating control. The WiFi electric underfloor heating thermostat supports Tuya remote control.
This page explains how the WiFi electric underfloor heating thermostat works in real projects. It includes functional explanation, wiring reference, and key technical parameters. Model configuration logic and project customisation possibilities are also described. Typical installation questions and practical deployment considerations are also provided.
Key Functional Highlights
(The core control functions and their practical value.)
01. WiFi Remote Heating Control
The WiFi electric underfloor heating thermostat allows remote temperature control through the Tuya mobile application. Users can change settings and check system status from a smartphone. This helps manage electric floor heating systems conveniently in residential projects. We have a standalone model HTW-ECB6-16A1.
02. Dual Sensor Temperature Monitoring
The thermostat supports both internal and external temperature sensors. The internal sensor measures room temperature during daily operation. The external probe monitors floor temperature and helps protect heating cables.
03. Multilingual App Interface
The mobile application supports seventeen common interface languages. Users in different regions can operate the WiFi electric underfloor heating thermostat easily. This improves usability for international HVAC projects.

Guide
(This section explains what configuration the model code refers to.)
| Heating series | xx stands for |
|---|---|
| 3A | Water Heating, with NC+NO+COM output terminals |
| 16A | Electric Underfloor Heating, with L+N line voltage output terminals + External Sensor |
| NV | Boiler Heating, with Non-Voltage Dry Contact |
| 1 / 3 | 1 = Standalone, 3 = Wi-Fi |
| Example | HTW-WF11-xx: if xx = 16A3, it stands for electric floor heating with external sensor support and Wi-Fi function. Most sub-models are ready-made. Kindly contact us to confirm availability. |
Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This thermostat is not suitable for industrial automation projects requiring Modbus or BACnet communication. Large BMS controlled buildings normally use other thermostat models designed for protocol integration.
Stable WiFi network conditions are required for remote control functions. Installations without internet access will limit app control features and should consider standalone thermostat versions.
Despite these limits mentioned above, functional adjustments can still be discussed. Communication behaviour, interface language options or control logic may be modified depending on project quantity and technical feasibility.
OEM cooperation is also available. Options may include logo printing, customised labels, packaging design or colour versions. Interface marking and product branding may also be adjusted for project partners.

Frequently Asked Questions
Can this WiFi electric underfloor heating thermostat work with most electric floor heating systems?
Yes. The thermostat switches electric heating loads through line voltage output terminals. This wiring structure fits most standard electric floor heating installations.
How does the external floor sensor work in this heating system?
The external sensor measures floor temperature directly. It helps prevent overheating and protects heating cables during continuous electric floor heating operation.
Does this thermostat support BMS communication such as Modbus or BACnet?
No. This model focuses on WiFi control through the Tuya platform. Projects requiring BMS communication should consider Modbus or BACnet thermostat versions.
Can the thermostat be controlled remotely through a mobile application?
Yes. The WiFi electric underfloor heating thermostat connects through Tuya WiFi. Users can adjust temperature, monitor status and control heating remotely.
What is the minimum order quantity and can samples be provided?
Thermostat samples are available for evaluation. The usual MOQ is about 300 units. Smaller quantities such as 100 units may also be discussed for project testing.
How can I place an order?
Please contact us to confirm your project requirements. We will provide a proforma invoice. Payment methods include TT, PayPal and Visa. Trade terms support EXW, FOB and DAP.
How long does product preparation normally take?
Non-customised samples are normally shipped within seven days. Customised projects require program evaluation and adjustment. Production for 300 units normally takes about one month.
What shipping options are available?
Express delivery such as FedEx, DHL or UPS normally takes about seven days. Air freight usually requires similar time. Sea freight normally takes around one month depending on destination.
