Quick Summary
The HTW-WF03-16A1 electric floor heating thermostat controls heating output with a 16A load and supports stable operation. The unit uses an external sensor for the floor temperature limit. This helps prevent overheating and protects floor materials.
This page explains how the electric floor heating thermostat works in real projects. It covers function meaning, wiring approach, and key technical details. It also touches on possible adjustments and common questions. The aim is to help with clear selection and smooth installation.
Key Functional Highlights
(This section introduces the main control functions and their engineering value in the specific HVAC system.)
(01) Electric Heating System Control (16A)
This electric floor heating thermostat is designed for electric heating systems with a 16A load. It can drive the heating load directly without extra devices. This keeps the wiring simple on-site. It also helps ensure steady and reliable heating control.
(02) Colourful LED Display with Adjustable Brightness
The LED display shows clear temperature and working status during use. Brightness can be adjusted for different room conditions. This helps avoid strong light at night. It makes daily operation more comfortable and easy to follow.
(03) Weekly Programmable Function
This electric floor heating thermostat features a weekly programmable function, which allows users to set heating periods based on daily routines. This reduces the need for manual changes. It helps avoid unnecessary heating during empty periods. Over time, this supports better energy use in real projects.
(04) Energy-saving Mode
Energy-saving mode reduces heating output when full comfort is not needed. This is useful during standby or low-use periods. It helps lower running costs.
(05) External Sensor with Overheat Protection
This electric floor heating thermostat comes with an external sensor that measures floor temperature directly during operation. It works with control logic to limit overheating. This is important for sensitive floor materials. It helps keep the system safe during long heating cycles.

Project Fit & Customisation
(This section describes project suitability, system limitations, and available customization options.)
This electric floor heating thermostat is not suitable for water heating or boiler systems. It does not support BMS integration such as Modbus or BACnet. Remote app control is not available. It is also not designed for wet or outdoor installation conditions.
Despite these limits mentioned above, some function adjustments can be discussed. Control logic or interface options may be adapted based on project needs. Changes must follow load and safety requirements. Final solutions are confirmed after technical review.
OEM customisation is available for different market needs. This includes logo printing, colour changes, and label updates. Packaging style can also be adjusted. These options help match project branding and installation requirements.
Certificates and Compliance
(This thermostat complies with European market requirements and is supported by certifications such as CE, RoHS, LVD test reports, EMC test reports, etc)
Exhibition Moments
(Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.)
Frequently Asked Questions
Q1: Can this electric floor heating thermostat be used with water heating systems?
No, this model is only for electric floor heating systems. It does not support water heating control. System matching should be confirmed before use.
