Quick Summary
The HTW-WKT18-316A1 Wireless Thermostat is designed for water and electric heating systems. It uses a wireless panel and receiver structure. The 3A output controls water heating, while 16A controls electric heating. The internal sensor ensures stable temperature control in standard indoor environments.
This page explains how the Wireless Thermostat works in real projects. It covers control logic, wiring, and key parameters. It also includes installation guidance and typical questions. OEM and ODM options are available for project-based requirements.
Key Features
(This section explains the core control functions and their practical value.)
(01) Dual heating control in one device
This Wireless Thermostat supports both water heating and electric heating systems. It integrates 3A and 16A outputs. This reduces the need for separate devices. It simplifies system design in mixed heating projects. If you only need electric heating thermostat, you can refer to this link: HTW-WKT18-16A1.
(02) Wireless connection for easy installation
The panel connects to the receiver wirelessly. No control wiring is required between them. This reduces installation time. It is suitable for retrofit or finished building environments.
(03) Battery powered control panel design
The control panel uses 2 AA batteries or USB power. It does not need fixed wiring. This allows flexible placement. It is useful in projects with limited wiring access.
(04) Internal sensor based temperature control
The wireless thermostat uses an internal NTC sensor. The control logic is simple and stable. It maintains indoor temperature within set range. It is suitable for standard residential applications.
