Quick Summary
HTW-WT19P is a boiler heating thermostat designed for simple heating control. It uses a wireless connection between the thermostat and receiver. The receiver switches the boiler through a 3A relay output. It supports heating demand control with stable on/off operation and basic protection logic.
This page explains how the wireless thermostat works in real projects. It covers control functions, system logic, wiring setup, and key parameters. It also includes common questions and practical selection advice. Custom options can be discussed based on project needs.
Key Functional Highlights
(This section explains the main control functions and engineering value of this boiler heating thermostat in heating systems.)
(01) 3A output for boiler control
This thermostat is designed for boiler heating applications with a 3A resistive load. It uses a simple relay output for stable switching. This helps ensure reliable heating operation in small residential systems.
(02) Wireless thermostat and receiver design
The system includes a thermostat and a receiver connected wirelessly. The receiver is wired to the heating system. The thermostat can be placed on a table, making operation easier. The transmission range reaches up to 100 metres in open space.
(03) Low temperature protection
The thermostat includes a frost protection function for safety. When the room temperature drops below 5°C, heating starts automatically. This works even when the unit is turned off. It helps prevent freezing in winter conditions.
(04) Programmable function
The programmable mode allows users to set heating schedules. This reduces manual adjustment during daily use. It also helps improve energy efficiency over time. The setup is simple and suitable for home users.
(05) Black VA screen display
The thermostat uses a black VA screen for clear visibility. The display is easy to read in different lighting conditions. Key information is shown clearly for daily operation. This improves user experience and reduces mistakes.

Project Fit & Customisation
(This section describes project suitability, system limitations, and customisation options for this boiler heating thermostat.)
This model is not suitable for BMS integration, like Modbus communication systems. It cannot connect to WiFi. It is also not designed for large commercial HVAC systems or high-load applications.
Despite the limitations mentioned above, the working logic and functions can be adjusted to meet project needs. Communication method, control logic, and interface can be evaluated. This depends on the order quantity and technical requirements.
OEM customisation is supported for branding and appearance. Logo printing, label design, and colour changes can be arranged. Packaging and user interface details may also be discussed for project use.
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 model work with all boiler systems?
It works with most standard boilers. Please check the voltage and load before use. For special systems, confirmation is recommended.
Q2: Does it support external sensors?
This model uses an internal temperature sensor only. External sensor input is not available. Custom versions may be evaluated if required.
Q3: How stable is the wireless connection?
The connection uses 433MHz FSK for stable communication. In open space, it can reach up to 100 metres. Walls or interference may reduce this distance.
Q4: Can it be used in commercial projects?
It is mainly designed for residential or small projects. For larger systems, other models may be more suitable. Communication models are recommended in such cases.
Q5: What is the MOQ and can we get samples?
We support sample orders for testing. Standard MOQ is 300 units. Smaller trial quantities like 100 units can be discussed.
Q6: How do we place an order?
Please feel free to get in touch with us to confirm your needs. We will provide a PI after confirmation. Payment supports TT, PayPal, and Visa.
Q7: How long does it take to prepare?
Standard samples are ready within 7 days. Custom orders usually take 3–5 weeks. Bulk orders like 300 units need about one month.
Q8: How will the goods be shipped?
Courier delivery takes around 7 days to door. Air shipping is similar in time. Sea shipping usually takes about one month or longer.
