Quick Summary
The HTW-WF02-NV WiFi Water Gas Boiler Heating Thermostat is designed for boiler heating systems. It works with water heating or gas boiler installations. The thermostat uses a non-voltage dry contact output to control the boiler signal circuit. It monitors room temperature and switches the heating circuit automatically.
This page explains how the WiFi Water Gas Boiler Heating Thermostat works in heating installations. It describes the control functions, wiring reference and technical parameters. It also introduces configuration meaning, project customisation options and typical installer questions.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
(01) WiFi remote heating control
The WiFi Water Gas Boiler Heating Thermostat supports mobile application control through Tuya WiFi. Users can adjust heating settings remotely. This allows flexible temperature management and helps maintain comfort when occupants return home. If you do not require WiFi function, you can refer to this link: HTW-WF02-NV1.
(02) Dry contact boiler control
The thermostat uses a non-voltage dry contact output for boiler control. This design ensures safe connection with most boiler terminals. The WiFi Water Gas Boiler Heating Thermostat switches the heating signal without supplying voltage.
(03) Clear LCD touch interface
A negative LCD screen with white UI and white backlight provides clear visibility. Users can read temperature information easily. The touch interface helps users operate the WiFi Water Gas Boiler Heating Thermostat comfortably.
(04) Mobile application language support
The mobile application supports seventeen mainstream languages. This allows easier configuration in different countries. Installers and users can operate the WiFi Water Gas Boiler Heating Thermostat without language barriers.

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 | Example HTW-WF11-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 Water Gas Boiler Heating Thermostat is not suitable for electric floor heating systems that require line-voltage heating output. It also does not support complex building management integration or advanced HVAC automation networks. Projects requiring Modbus, BACnet or centralised building control systems normally require other thermostat models designed for BMS communication.
Despite these limits mentioned above, ODM customisation may still be discussed for certain projects. Communication protocols, firmware behaviour or application interface adjustments may be possible. Each modification must be reviewed by engineers and confirmed according to production feasibility and project scale.
OEM cooperation is also supported for distributors and brand partners. Custom options include OEM logo printing, colour customisation, customised product labels and packaging design. These services help partners integrate thermostats into their own HVAC product portfolios.

Frequently Asked Questions
Q1. What systems can this WiFi Water Gas Boiler Heating Thermostat control?
It works with water heating systems and gas boiler systems using dry contact control signals.
Q2. Does the WiFi Water Gas Boiler Heating Thermostat supply voltage to the boiler?
No. The thermostat provides a non-voltage dry contact signal to start or stop the boiler heating circuit.
Q3. Can the WiFi Water Gas Boiler Heating Thermostat be used without WiFi?
Yes. The thermostat works locally as a normal room thermostat. WiFi mainly enables remote monitoring and temperature adjustment through the mobile application.
Q4. What is the minimum order quantity and are samples available?
Thermostat samples are available. Standard MOQ is around 300 units, but smaller quantities may sometimes be discussed for project testing.
Q5. How can we place an order?
Please contact us first. After confirming project requirements, we will provide a proforma invoice. Payment methods include TT, PayPal, Visa, etc. Terms support EXW, FOB, DAP and more.
Q6. How are the products normally shipped?
Courier door-to-door delivery usually takes about seven days. Air freight takes similar time, while sea freight normally requires over one month depending on destination.
