Quick Summary
The HTW-WF02RP-3ANV boiler thermostat is designed for water heating and boiler heating systems. It provides stable control with Wi-Fi app access and simple scheduling. The unit supports timer operation and frost protection for safe unattended use. It fits typical home heating control setups.
This page explains how this boiler thermostat works in real heating projects. It helps users understand control logic, wiring setup, and key parameters. It also covers model options, project fit, and common questions. The aim is to support correct selection and smooth project use.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the specific HVAC system.)
(01) For Water Heating or Boiler Heating System
This boiler thermostat supports both water heating and boiler heating systems. It uses simple on/off control to keep the room temperature stable. This control method fits most home heating systems and keeps operation clear and reliable.
If one needs the electric underfloor heating thermostat instead of this water/boiler type, this model can be referred to (click → HTW-WF02RP-16A)
(02) LED Display with Adjustable Brightness
The thermostat uses an LED display to show temperature and settings clearly. Brightness can be adjusted to suit different room conditions. This helps improve visibility without causing disturbance, especially in bedrooms or low-light areas.
(03) Wi-Fi Control with Tuya App
Wi-Fi connection allows control through the Tuya mobile application. Users can change settings remotely at any time. This improves daily use and gives better control when users are away from home.
(04) Programming Function and Timer Control
The thermostat supports weekly programming and timer on/off settings. Users can set heating periods based on daily routines. This helps reduce energy use and keeps indoor temperature stable throughout the day.
(05) Anti-Frozen Protection Function
The thermostat activates heating when temperature drops to around 5°C. This prevents pipes from freezing during cold conditions. It protects the heating system and reduces risk when the space is not occupied.

Project Fit & Customization
(This section describes project suitability, system limitations, and available customization options.)
This boiler thermostat is not designed for complex BMS integration projects. It does not support protocols like Modbus or BACnet. It is also not suitable for high load electric heating systems. The control logic is simple and not made for multi-zone control systems.
Despite these limits mentioned above, function changes can still be discussed. Communication type or control behaviour can be adjusted if needed. We support ODM cooperation within a clear and agreed technical scope.
OEM customisation is also available for project branding needs. This includes logo printing, label design, and housing colour changes. Packaging and interface details can also be adjusted for project use.
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.)
