Quick Summary
HTW-WT13P-WF is a smart wifi thermostat made for water heating systems with 3A load control. It controls heating through a receiver linked to the boiler or actuator. The system supports heating mode with frost protection logic and simple scheduling. It is a wireless thermostat that can be placed freely for daily use.
This page explains how the control works in real heating projects and what each function does. It also helps confirm key parameters and basic wiring logic before selection. Common questions and simple custom options are also included. This helps reduce errors during the planning and installation stages.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in water heating control systems.)
(01) 3A load for water heating system
This model is designed for water heating control with a 3A resistive load output. It fits boilers or actuators with low current demand. This helps keep switching safe and stable. It is suitable for small heating zones and daily operation.
(02) Wireless thermostat and receiver structure
The system includes a thermostat and a receiver working together wirelessly. The receiver connects to the heating system and controls output. The thermostat can be placed on a desk or wall. This improves flexibility and reduces wiring work on site.
(03) Frost protection function
The thermostat starts heating when the room temperature drops below 5°C. This works even when the system is off. It helps prevent pipe freezing in cold weather. This protects the heating system and reduces maintenance risks.
(04) Programmable function
The programmable function allows temperature control based on daily time schedules. This reduces the need for manual adjustment. It helps keep comfort stable during use. It also supports better energy control in heating projects.
(05) WiFi app control
This smart wifi thermostat supports remote control through a mobile app. Users can adjust temperature anytime when powered by USB. This improves daily convenience and system access. It is useful for remote monitoring and quick changes.

Project Fit & Customisation
(This section describes project suitability, system limitations, and available customisation options.)
This model is not suitable for high-power electric heating systems. It cannot control loads above 3A directly. It also does not support BMS protocols like Modbus or BACnet. Battery mode cannot support smart wifi thermostat operation.
Despite these limitations mentioned above, working logic and some functions can be evaluated or customised based on project needs and order quantity.
OEM customization is also available for branding and product appearance. This includes logo printing, colour changes, and packaging design. Label content and interface language can also be adjusted. This helps match different market 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: Is this model suitable for all heating systems?
This model is made for water heating systems with low load control. It is not suitable for electric heating with high power. Please check load needs before selection.
Q2: Can it connect to a BMS system?
This model does not support Modbus or BACnet communication. It works as a wireless thermostat or app control device. For BMS projects, other models are better.
Q3: How does the wireless connection work?
The thermostat connects to the receiver using 433MHz frequency. The signal is stable within 100 metres in open space. This helps reduce wiring work during installation.
Q4: Does it support external sensors?
This model uses an internal temperature sensor. External sensors are not included by default. Some changes may be discussed for project needs.
Q5: What is the MOQ and can we get samples?
We support sample orders for testing and checking. Standard MOQ is 300 units. Smaller trial orders like 100 units can be discussed.
Q6: How do we place an order and arrange shipment?
After confirming needs, we will provide a PI. Payment supports TT, PayPal, and Visa. Terms include EXW, FOB, and DAP.
Q7: How long does it take to prepare the products?
Standard samples are ready within 7 days. Custom orders need evaluation and software changes. Bulk orders like 300 units usually take about one month.
Q8: How are the goods shipped?
Courier delivery is common and takes about 7 days. Air freight has similar timing. Sea shipping takes around one month based on destination.
