Quick Summary
HTW-WKT25-3ANV3 is a WiFi Water Heating Thermostat for water and boiler heating systems. It controls heating output using relay switching and temperature sensing. The unit supports LED slide operation for direct adjustment. WiFi allows remote control through mobile application for flexible daily operation.
This page explains how the WiFi Water Heating Thermostat works in projects. It covers control logic, wiring method, and parameter 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 Slide-Based Control Interface
The WiFi Water Heating Thermostat uses slide up and down operation for temperature setting. This reduces button wear and improves control response. It allows quick adjustment and supports stable operation during daily use.
02 Stable Heating Output Control
The WiFi Water Heating Thermostat controls heating through relay switching based on temperature feedback. It reduces temperature fluctuation during operation. This helps maintain steady comfort and supports reliable system performance.
03 WiFi Remote Management
WiFi allows remote control through mobile application for temperature adjustment. Users can manage heating without visiting the room. This improves flexibility and supports central control in multi-room applications. The model HTW-WKT25-16A3 is the same series which can support electric heating system with WiFi function.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This WiFi Water Heating Thermostat is not suitable for electric floor heating systems. It does not support fan coil control. It is not designed for complex BMS protocols like Modbus. It is intended for water heating and boiler systems only.
Despite these limits mentioned above, ODM customisation can be discussed. Control logic or communication method may be adjusted. Interface behaviour or display style can also be adapted. Final solution depends on technical evaluation.
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 projects.
