Quick Summary
HTW-WKT25-BP is a Wired boiler heating thermostat designed for boiler heating systems. It controls heating output using dry contact switching and temperature sensing. The unit is battery powered with 3×AAA supply. LED slide operation allows simple and stable temperature adjustment during daily use.
This page explains how the Wired boiler 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 Battery Powered Operation
The Wired boiler heating thermostat uses 3×AAA batteries for power supply. This removes the need for line voltage wiring. It simplifies installation and improves flexibility in retrofit or replacement projects.
02 Slide-Based Temperature Control
The thermostat uses slide up and down operation for temperature setting. This reduces mechanical wear and improves user interaction. It allows quick adjustment and supports stable control during daily operation.
03 Boiler Control via Dry Contact
The Wired boiler heating thermostat controls boiler systems using dry contact output. This matches common boiler control requirements. It ensures reliable switching and stable system operation in heating applications. We have another model HTW-WKT25-RF3 can support wireless boiler heating system and WiFi function.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This Wired boiler heating thermostat is not suitable for electric floor heating systems. It does not support water valve control or fan coil systems. It is not designed for WiFi or BMS integration. It is intended for simple standalone boiler control only.
Despite these limits mentioned above, ODM customisation can be discussed. Control logic or output type may be adjusted. Interface behaviour or sensing options can be modified. Final solution depends on technical evaluation and project requirements.
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.
