Quick Summary
The HTW-WKT13-PRO WiFi Wireless Boiler Thermostat is designed for boiler heating systems. It uses wireless RF communication between transmitter and receiver. It supports WiFi control and programmable schedules. This ensures stable temperature control and flexible installation in HVAC heating projects.
This page explains how this WiFi Wireless Boiler Thermostat works in real applications. It includes control logic, wiring guidance, and key parameters. It also covers installation considerations and typical project questions. Basic OEM and ODM options are also introduced for project matching.
Key Features
(This section explains the core control functions and their practical value.)
01 Wireless RF communication design
This WiFi Wireless Boiler Thermostat uses RF868MHz communication between transmitter and receiver. It removes direct wiring between control point and boiler. This helps reduce installation time and improves flexibility in retrofit projects. For the underfloor heating thermostat, you can refer to this link: HTW-WF07RP-16A-B.
02 Programmable temperature control
The thermostat supports 7-day and 4-period scheduling. It allows different temperature settings throughout the day. This improves comfort while reducing unnecessary energy use in heating systems.
03 WiFi remote management
The thermostat connects to mobile applications via WiFi. It supports remote control from both iOS and Android devices. This allows easier management across multiple rooms or projects.
04 Stable relay output for boiler control
The receiver provides 230V relay output with NO and NC contacts. It ensures stable switching for boiler systems. This improves system reliability and reduces control errors during operation.

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This WiFi Wireless Boiler Thermostat is not suitable for systems requiring wired control signals. It does not support BMS integration such as Modbus or BACnet. It is also not designed for electric floor heating systems.
Despite these limits mentioned above, ODM customisation can be discussed. Communication pairing logic and control behaviour may be adjusted. Interface changes and function tuning can be evaluated. Final solutions depend on project feasibility.
OEM customisation is available for branding and packaging. This includes logo printing, product colour, and label design. Interface layout adjustments can also be discussed. These options help adapt the product for different markets.
