Quick Summary
The HTW-WT13P wireless thermostat is designed for water heating systems in residential projects. It controls a boiler or heating valve through a 3A receiver. The thermostat and receiver connect wirelessly. It also supports programmable schedules and frost protection for safe operation.
This page explains how the wireless thermostat works in heating control. It covers control logic, system setup, and key parameters. It also helps clarify common questions and shows what can be adjusted for different project needs.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in water heating HVAC systems.)
(01) 3A relay for water heating control
The 3A relay is designed for common water heating loads. It switches boilers or valves under normal conditions. This avoids the need for extra relays in small systems. It also helps keep the wiring simple and stable.
(02) Wireless thermostat with receiver structure
The wireless thermostat works together with a separate receiver unit. The receiver is installed near the heating system. The thermostat can be placed freely, such as on a desk. This reduces wiring work and improves user convenience.
(03) Frost protection function
Frost protection works even when the system is turned off. When the room temperature drops below 5°C, heating starts automatically. This helps protect pipes in cold weather. It improves safety without needing manual action.
(04) Programmable heating schedules
The programmable function allows daily temperature settings. Users can adjust heating based on their routine. This reduces manual changes during the day. It also helps improve comfort and energy efficiency.
(05) Set-point limitation
Set-point limitation allows us to define minimum and maximum temperature limits and prevents us from setting extreme values, which helps avoid energy waste in shared spaces.

Project Fit & Customization
(This section describes project suitability, system limitations, and available customization options.)
This wireless thermostat is not suitable for systems needing WiFi or app control. It does not support BMS communication like Modbus or BACnet. It is also not designed for loads above 3A. High-power systems will require a different solution.
Despite these limitations mentioned above, working logic and some functions can be evaluated or customised based on project needs and order quantity. Adjustments may include control timing or pairing logic. All changes depend on technical review.
OEM customisation is supported for different project needs. This includes logo printing, labels, and packaging. Colour changes and interface adjustments may also be discussed. Final options depend on order quantity.
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 wireless thermostat work with all heating systems?
This model is designed for water heating systems. It controls boilers or valves through the receiver. The load must stay within 3A.
Q2: Does it support an external sensor?
This model uses a built-in temperature sensor. It does not support an external sensor. Custom versions may be discussed if required.
Q3: Can it connect to a BMS system?
This wireless thermostat does not support BMS protocols. It is made for standalone heating control. Other models are needed for integration.
Q4: How far can the thermostat communicate with the receiver?
The distance can reach up to 100 metres without obstacles. Walls may reduce the range. Good placement helps keep the signal stable.
Q5: What is the MOQ and can we get samples?
We support sample orders for testing. Standard MOQ is 300 units. Smaller quantities like 100 units can be discussed.
Q6: How do we place an order and arrange shipping?
