Quick Summary
HTW-WKT25-RF3 is a WiFi Wireless Boiler Heating Thermostat for boiler heating systems. It uses RF868MHz communication between transmitter and receiver. The transmitter is battery powered, while the receiver uses AC supply. WiFi allows remote control through mobile application for flexible system management.
This page explains how the WiFi Wireless Boiler Heating Thermostat works in projects. It covers control logic, wireless connection, and wiring setup. It also explains model configuration and customisation options. Typical questions and answers are included for quick reference.
Key Features
(This section explains the core control functions and their practical value.)
01 Wireless RF Communication
The WiFi Wireless Boiler Heating Thermostat uses RF868MHz communication between transmitter and receiver. This reduces wiring complexity during installation. It improves flexibility in retrofit projects and supports stable signal transmission. We have another model HTW-WKT25-BP which support wired boiler heating system with WiFi function.
02 Dual Power Supply Design
The transmitter uses 3×AAA batteries, while the receiver uses AC power supply. This allows flexible installation placement. It ensures stable operation and reduces wiring limitations in different project conditions.
03 WiFi Remote Control Integration
WiFi allows remote control through mobile application for temperature adjustment. Users can manage heating without direct access. This improves system flexibility and supports efficient control in residential or commercial projects.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This WiFi Wireless Boiler Heating Thermostat is not suitable for electric floor heating systems. It does not support fan coil or water valve control. It is not designed for complex BMS protocols like Modbus. It is intended for wireless boiler control only.
Despite these limits mentioned above, ODM customisation can be discussed. Communication protocol or RF configuration may be adjusted. Interface behaviour or control logic can be modified. Final solution depends on technical evaluation and project needs.
OEM services are available for branding and appearance changes. Logo printing, colour options, and label design can be supported. Packaging and interface adjustments may also be arranged for bulk production.
