Quick Summary
HTW-WF02-3A is a wifi water heating thermostat designed for indoor water heating systems. It controls heating equipment through NC, NO, and COM relay outputs. The thermostat monitors room temperature using an internal NTC sensor. It switches the heating circuit to keep the room temperature stable.
This page explains the working logic of the wifi water heating thermostat in typical heating systems. It also provides wiring reference, technical specifications, and model code guidance. Project use limits and customisation options are briefly explained. Common installation and purchasing questions are answered at the end.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
(1) Stable Temperature Control for Water Heating Systems
The wifi water heating thermostat controls water heating equipment through relay outputs. It measures room temperature and switches the heating circuit when needed. This helps maintain steady indoor temperature and avoids unnecessary heating operation. Please refer to this link if you are interested in underfloor heasting system: HTW-WF02-16A1.
(2) Remote Temperature Management via Mobile App
The wifi water heating thermostat connects to a mobile application through WiFi communication. Users can adjust the temperature setting remotely. This function helps homeowners and property managers supervise heating operation without direct access to the thermostat.
(3) Multi-language Interface for International Projects
The thermostat application supports seventeen mainstream languages. This makes the wifi water heating thermostat easier to deploy in international projects. Installers and users can operate the system without language barriers during installation or daily use.
(4) Clear Display Interface for Daily Operation
The thermostat uses a negative screen interface with white backlit display. Temperature and operation status remain easy to read in different lighting conditions. This improves usability for everyday heating control.

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 external sensor |
| NV | Boiler Heating with Non-Voltage Dry Contact |
| 1/3 | 1 = Standalone, 3 = Wi-Fi |
| 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 heating thermostat is not suitable for high-power electric floor heating systems that require 16A load output. It is also not designed for fan coil temperature control. The model does not support industrial heating control systems or complex building automation networks.
Despite these limits mentioned above, ODM functional customisation may still be discussed. Communication options, display interface adjustments, or sensor configuration may be modified for certain projects. These changes normally depend on project quantity and technical feasibility.
OEM services are also available for distributors and project partners. Custom logo printing, colour changes, product labels, and packaging design can be arranged. These options help partners align the thermostat with their brand identity.

Frequently Asked Questions
Q1. Can this thermostat control all water heating systems?
It works with most standard water heating systems using relay control. Installers should confirm wiring compatibility with the heating equipment before installation.
Q2. Does the wifi water heating thermostat require internet for operation?
Basic temperature control works locally without internet. WiFi connection is only required when remote monitoring or app control is used.
Q3. Is this thermostat suitable for large commercial heating systems?
This thermostat is designed mainly for residential or small heating projects. Large central heating systems usually require specialised control equipment.
Q4. What is the minimum order quantity and are samples available?
Thermostat samples are available for testing. Standard minimum order quantity is around 300 units, but smaller trial orders can sometimes be discussed.
Q5. How can I place an order?
Please contact our team to confirm product requirements. We will issue a proforma invoice after confirmation. Payment methods include TT, PayPal, Visa and others.
Q6. How will the thermostats be shipped?
Courier door-to-door delivery normally takes about seven days. Air freight is similar, while sea freight usually takes one month or longer depending on destination.
