Quick Summary
HTW-WF10-NV3 is a WiFi Water Gas Boiler Heating Thermostat for water and gas boiler systems. It uses 3A non-voltage dry contact output for control. The unit operates on 95–240Vac power supply. WiFi enables remote control through mobile application for flexible operation.
This page explains how the WiFi Water Gas 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 WiFi Remote Control
The WiFi Water Gas Boiler Heating Thermostat supports remote control through mobile application. Users can adjust temperature settings without being on site. This improves flexibility and helps manage heating systems in daily operation. We have another standalone model HTW-WF10-NV1.
02 Dry Contact Boiler Control
The thermostat uses non-voltage dry contact output to control boilers safely. This matches common water and gas boiler systems. It ensures reliable switching and stable operation in heating projects.
03 Stable Temperature Control
The internal sensor monitors room temperature continuously. The system adjusts heating output based on setpoint. This helps maintain consistent comfort and reduces temperature fluctuation in daily use.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This WiFi Water Gas Boiler Heating Thermostat is not suitable for electric floor heating systems. It does not support water valve control or fan coil systems. It cannot be used for complex BMS integration. It is designed for simple boiler control with WiFi access only.
Despite these limits mentioned above, ODM customisation can be discussed. Communication protocol or control logic may be adjusted. Interface behaviour or sensing options can be modified. Final solution depends on technical review and project needs.
OEM services are available for branding and product appearance. Logo printing, colour changes, and label design can be supported. Packaging and interface layout can also be customised for project delivery.
