Quick Summary
This water heating thermostat model HTW-TFT12-3ANV1 is designed for water heating and boiler systems. It controls heating output based on room temperature and time schedules. The thermostat supports programming, holiday mode, and anti-frozen protection for safe and stable system operation. It also features a colourful touch screen with five interfaces and multi-language display.
This page explains how the control works in real use. It also covers wiring, key parameters, and project considerations for water heating thermostat and boiler system applications.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the specific HVAC system.)
(01) For both water heating and boiler heating system
This water heating thermostat can be used for both water heating and boiler systems. It is connected to different terminals based on system requirements. This helps keep one model across projects and reduces selection complexity.
If one is looking for an electric underfloor heating thermostat, one may refer to this model instead (HTW-TFT12-16A1).
(02) Colourful touch screen，5 interfaces
The thermostat uses a colourful touch screen with five interface layouts. It provides a clear status display and simple operation. This helps improve daily use and reduces confusion during setup.
(03) Multi-language display (configurable)
The interface supports multiple languages and can be configured as needed: Chinese, English, Italian, Russian, French, Polski, Spanish, German, and Czech. This is useful for projects in different regions. It helps reduce training effort and improves usability.
(04) Programming function + Holiday setting
The thermostat supports weekly programming for temperature control. During holidays, it follows the weekend setting from the program. This helps maintain basic heating while avoiding unnecessary energy use.
(05) Anti-freeze function
When the temperature drops to a low level, heating starts automatically. The trigger can be set between 3°C and 7°C. This helps prevent the room from getting too cold when unoccupied.

| Example | HTW-TFT12-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 & Customisation
(This section describes project suitability, system limitations, and available customisation options.)
This water heating thermostat is not suitable for high-power electric heating loads above its rated output. It does not support BMS communication protocols. It is also not designed for centralised control or remote app-based operation.
Despite these limits mentioned above, function customisation can be discussed. Communication types like Wi-Fi or Modbus, control logic, or display language may be customised if required. Each project should be reviewed to confirm feasibility — please feel free to get in touch with us.
OEM customisation is also supported for this water heating thermostat. This includes logo printing, housing colour change, and label design. Packaging and manuals can also be adjusted based on project needs.
Certificates and Compliance
(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.)
Frequently Asked Questions
Q1: Can this thermostat work for both water heating and boiler systems?
Yes, this model supports both system types. Wiring is set based on the terminal connection. It helps simplify use across different heating setups.
Q2: What temperature sensor is used?
The thermostat uses a built-in NTC3950 sensor. It provides stable temperature feedback. This supports reliable room control.
Q3: How does the anti-freeze function work?
When the temperature drops below a set level, heating starts automatically. The threshold can be adjusted between 3°C and 7°C, helping protect the system when it is not in use.
Q4: Is this suitable for large building projects?
This model is designed for standalone room control. It does not support BMS integration. It is more suitable for residential or small commercial use.
Q5: What is the MOQ, and can samples be provided?
Yes, we support samples for testing. Standard MOQ is around 300 units. Smaller trial orders, such as 100 units, may be discussed.
Q6: How do we place an order and arrange shipment?
After confirming requirements, we provide a Proforma Invoice for your reference. Payment supports TT, PayPal, Visa. Terms include EXW, FOB, DAP, etc.
Q7: How long does production take?
Non-custom samples are sent within 7 days. Custom orders usually take 3–5 weeks. Around 300 units typically need about one month.
Q8: What shipping methods are available?
Courier delivery takes about 7 days door-to-door. Air freight also takes around 7 days. Sea freight usually takes more than one month.
