Colorful Knob 16A WiFi Electrical Underfloor Heating Thermostat With Internal and External Sensor

Key Functional Highlights

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

01 Heating Output Control Logic
The WiFi Electrical Underfloor Heating Thermostat uses relay output to control electric heating load. It compares measured temperature with setpoint. This maintains stable heating output and avoids frequent switching in operation.

02 Dual Sensor Temperature Management
The thermostat supports internal and external sensors for better temperature control. Internal sensor manages room temperature. External sensor limits floor temperature and protects heating surface from overheating during long operation.

03 WiFi Remote Control Function
WiFi allows remote access through mobile application for control and monitoring. Users can adjust temperature without local access. This improves flexibility in daily use and simplifies project management in multiple rooms. If you do not need WiFi function, please refer to this link:HTW-WF10-16A1.

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 WiFi Electrical Underfloor Heating Thermostat is not suitable for water or boiler systems. It does not support valve control or fan coil systems. It is not designed for BMS protocols like Modbus or BACnet. It works only with resistive electric heating loads.

Despite these limits mentioned above, ODM customisation can be discussed. Communication method or app interface may be adjusted. Control logic or sensor settings can also be modified based on project needs. Final solution depends on technical evaluation.

OEM services are also available for branding and appearance changes. Logo printing, colour adjustment, and label design can be supported. Packaging or minor UI changes may also be arranged for bulk orders.
