Key Functional Highlights

(This section explains the core control functions and their practical value.)

01 Temperature Control Logic
The Electric Underfloor Heating Thermostat uses sensor feedback to control heating output. It compares room temperature with the setpoint. The relay switches heating load to maintain stable floor temperature.

02 Dual Sensor Support
The thermostat supports both internal and external sensors for temperature detection. Internal sensor manages room air temperature. External sensor protects floor surface from overheating and improves control accuracy.

03 Simple User Interaction
The knob design allows direct adjustment without complex menus. The white backlit display shows clear temperature readings. This improves usability in daily operation and reduces setup errors. For WiFi function, please refer to this model HTW-WF10-16A3.

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-WF10-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 Electric Underfloor Heating Thermostat is not suitable for water or boiler systems. It does not support valve control or fan coil systems. Standalone models do not support BMS protocols or remote app control. It is designed for resistive electric heating loads only.

Despite these limits mentioned above, ODM customization can be discussed. Communication protocol or control logic may be adjusted for project needs. Sensor type or control range can also be adapted after evaluation. Final feasibility depends on project details.

OEM services are also available for branding requirements. This includes logo printing, colour changes, and label design. Packaging and minor interface changes can also be supported for bulk orders.
