Quick Summary
HTW-ECB6-16A1 is an electric underfloor heating thermostat designed for electric floor heating systems. It switches the heating load through L and N line voltage output terminals. Both internal and external sensors measure temperature for stable control. This electric underfloor heating thermostat operates with 95–240Vac power and a white backlit display.
This page explains how the electric underfloor heating thermostat works in real projects. It clarifies control functions, wiring reference, and key technical parameters. Model configuration logic and project customisation options are also explained. Typical installation questions and practical deployment details are included.
Key Functional Highlights
(The core control functions and their practical value.)
01. Line Voltage Heating Control
The electric underfloor heating thermostat switches electric heating loads through L and N line voltage terminals. This control method fits most electric floor heating installations. It allows stable switching and reliable heating control in residential heating projects. This is the standalone version, we have another version which have WiFi function: HTW-ECB6-16AB.
02. Dual Temperature Sensing
The thermostat supports both internal and external temperature sensors. The internal sensor measures room air temperature during normal operation. The external probe can monitor floor temperature to protect heating systems.
03. Clear Backlit Touch Interface
The electric underfloor heating thermostat uses a white backlit screen for clear reading. Users can check temperature and system status easily. The touch interface helps adjust the heating setpoint quickly.

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 building management system integration. It does not support Modbus, BACnet or other communication protocols. Projects requiring central monitoring or remote control should consider other thermostat models.
Standalone models also do not support mobile application control or cloud platforms. Remote operation through Wi-Fi or smart home systems is therefore unavailable. Projects requiring smart home integration should select Wi-Fi thermostat versions instead.
Despite these limits mentioned above, functional modification may still be discussed. Communication protocol or control logic may be adjusted when projects require special behaviour. However, all modifications depend on technical feasibility and project quantity.
OEM cooperation is also available for project partners. This may include logo printing, customised product labels, and packaging design. Colour adjustment or interface marking may also be discussed for project branding.

Frequently Asked Questions
Can this thermostat work with most electric underfloor heating systems?
Yes. The thermostat controls electric floor heating using line voltage output terminals. This wiring structure matches many common electric floor heating installations.
How does the external floor sensor work in a heating project?
The external sensor measures floor temperature directly. It helps protect heating cables and prevents floor overheating during long heating periods.
Does this thermostat support BMS communication such as Modbus or BACnet?
No. This model operates as a standalone controller. Projects requiring BMS communication should consider versions with Modbus or BACnet support.
How should engineers choose the correct thermostat model for a project?
The heating system type should be confirmed first. Engineers should check wiring method, load type, and sensor requirements before selecting a model.
What is the minimum order quantity and can samples be provided?
Yes, thermostat samples are available for evaluation. The usual MOQ is 300 units. Smaller quantities such as 100 units may be discussed for testing.
How can I place an order?
Please contact us to confirm technical requirements. We will provide a proforma invoice. Payment methods include TT, PayPal, and Visa. Terms support EXW, FOB, and DAP.
How long does product preparation normally take?
Non-customised samples are normally shipped within seven days. Custom projects require program adjustment and evaluation. Production for 300 units usually takes about one month.
What shipping options are available?
Express delivery such as FedEx, DHL, or UPS normally takes about seven days. Air freight is similar. Sea freight usually requires about one month depending on destination.
