Quick Summary
The HTW-WKT18-3ANV1 Wireless Heating Thermostat is designed for water and boiler heating systems. It uses a wireless panel and receiver structure. It supports 3A relay output for stable switching. The internal sensor controls temperature accurately in standard indoor environments.
This page explains how the Wireless Heating Thermostat works in real projects. It covers control logic, wiring, and key parameters. It also includes installation points and common questions. Basic OEM and ODM options are available for project needs.
Key Features
(This section explains the core control functions and their practical value.)
(01) Wireless control structure
This Wireless Heating Thermostat separates the control panel and receiver. It removes direct wiring between control and load. This helps reduce installation time and improves flexibility in retrofit or renovation projects. If you are interested in boiler heating thermostat, please refer to this link: HTW-WKT18-NV3.
(02) Dual heating system compatibility
The thermostat supports both water heating and boiler heating systems. It uses a 3A relay output for stable switching. This allows one model to cover more project types with simple configuration.
(03) Battery powered panel design
The control panel uses 2 AA batteries or USB power. It avoids fixed wiring constraints. This makes it easier to place the thermostat in the best position for accurate temperature sensing.
(04) Internal sensor temperature control
The wireless heating thermostat uses an internal NTC sensor for temperature detection. It keeps the control logic simple and stable. This is suitable for standard rooms where external sensing is not required.
Product Design and Display
(This section shows this wireless heating thermostat’s dimensions and the interface layout.)
The thermostat uses an LED screen with capacitive touch buttons. The panel design is simple and clean. The receiver is wall-mounted and compact. This design supports clear operation and practical installation.
