Quick Summary
HTW-HT09B-3ANV1 is a Water and Boiler Heating Thermostat for water heating and boiler systems. It controls heating output using relay switching and dry contact. The unit supports NC, NO, and COM terminals for flexible connection. It works with 100–240Vac supply and provides stable temperature control.
This page explains how the Water and Boiler Heating Thermostat works in projects. It covers control logic, wiring method, and parameter setup. It also explains model configuration and customisation options. Typical questions and answers are included for quick reference.
Key Features
(This section explains the core control functions and their practical value.)
01 Dual Output Heating Control
The Water and Boiler Heating Thermostat supports 2x3A load outputs with NC, NO, and COM terminals. It also includes dry contact for boiler control. This allows flexible connection for different heating system layouts. Another model HTW-HT09B-3ANV3 can support Tuya WiFi function.
02 Stable Temperature Regulation
The thermostat uses sensor feedback to control heating output based on setpoint. It reduces temperature fluctuation during operation. This helps maintain stable room comfort and improves system reliability.
03 VA Screen Interface
The VA screen provides clear temperature display with black background. It improves visibility under different lighting conditions. This helps users read settings easily and reduces operation errors in daily use.
