Quick Summary
The HTW-WF01-NV3 Gas Boiler Heating Thermostat is designed for indoor boiler heating systems. It sends control signals through a non-voltage dry contact output. The thermostat works with a 100–240 Vac power supply. Built-in sensing and external sensor support help maintain stable room temperature.
This page explains how the Gas Boiler Heating Thermostat works in real heating systems. It describes the control logic and wiring reference. Key parameters and installation guidance are also included. OEM and ODM options for the Gas Boiler Heating Thermostat can be discussed for projects.
Key Features
(The core control functions and their practical value.)
1. Dry Contact Boiler Control
This Gas Boiler Heating Thermostat uses a non-voltage dry contact output. The signal controls the start and stop command of a boiler. This control structure is common in residential heating installations.
2. WiFi Remote Heating Control
The thermostat supports WiFi connection through a mobile application. Users can change temperature settings remotely from a smartphone. This makes heating management easier in homes or apartments.(If you don’t need wifi, click here)
3. Programmable Temperature Scheduling
The thermostat supports programmable heating periods during the day. Users can define different temperature levels for different time blocks. This helps balance comfort and energy use.
4. External Temperature Sensor Support
An external sensor can measure temperature in another location. This helps improve temperature stability in larger rooms. It also supports more flexible heating control in complex spaces.

Model Code Guide
(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 / 2 / 3 | 1 = Standalone, 2 = Modbus, 3 = Wi-Fi |
| Example HTW-WF01-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
(Where the product can be used, its limits, and OEM/ODM options.)
This Gas Boiler Heating Thermostat is designed for boilers using dry contact signals. It cannot directly switch electric floor heating loads. Systems requiring high voltage switching should use other thermostat models. Installations requiring Modbus communication or building management integration should also select other versions.
Despite these limits mentioned above, some ODM cooperation may still be discussed. Communication options or control logic may be adjusted for projects. Our engineers review wiring conditions and heating system requirements before confirming technical solutions.
OEM customisation is also supported for brand projects. Logo printing on the thermostat panel can be arranged. Product labels and packaging design can also be customised. These options help the Gas Boiler Heating Thermostat match different branding and project needs.
Certifications
This thermostat complies with European market requirements and is supported by certifications such as CE, RoHS, LVD test reports, EMC test reports, etc
Exhibition Moments
Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.
