Quick Summary
The HTW-WF81-716 Wifi Electric Heating Thermostat is designed for electric floor heating systems. It supports 16A load control with L+N output terminals. The unit provides programmable control and mobile app access. Internal and external sensors improve safety and stable temperature control in daily use.
This page explains how the Wifi Electric Heating Thermostat works in real projects. It helps confirm wiring, parameter settings, and installation logic. It also supports basic selection and configuration understanding. Common questions are included to support quick project decisions.

Key Functional Highlights
(This section explains the core control functions and their practical value.)
(01) Wifi app control
The Wifi Electric Heating Thermostat supports remote control through a mobile app. Users can adjust temperature and schedules from different locations. This improves control flexibility and helps reduce energy waste during operation.
(02) Programmable scheduling
The thermostat supports time-based heating control with multiple periods. It allows automatic temperature adjustment during different times of the day. This reduces manual changes and helps maintain stable indoor comfort conditions.
(03) Internal and external sensor support
The thermostat supports both internal and external temperature sensors. The external sensor monitors floor or system temperature directly. This improves control accuracy and helps prevent overheating during long operation cycles.
(04) Knob Control with Negative Screen
The thermostat uses a knob interface with a negative display. This design provides simple operation. It also offers clear visibility in different lighting conditions.(Other design please click here)

Project Fit & Customization
(Where the product can be used, its limits, and OEM/ODM options.)
This Wifi Electric Heating Thermostat is not suitable for BMS systems. It does not support Modbus, BACnet, or central building control. It is not designed for outdoor use or wet areas. Projects needing strong protection or large system control should use other models.
Despite these limits mentioned above, function changes can be discussed. Communication or control logic may be adjusted for some projects. Sensor type or control range can also be modified. Final options depend on project size and technical review.
OEM services are supported for brand and product appearance. Logo printing, labels, and packaging can be customised. Colour changes and simple interface changes are also possible. These help match project needs and market positioning.
