Quick Summary
HTW-WF11-16A3 is a smart thermostat designed for electric heating systems. It controls electric underfloor heating through a 16A line voltage output. The thermostat supports programming schedules and Wi-Fi remote control. An external sensor monitors floor temperature to protect the electric heating system from overheating.
This page explains how the electric heating thermostat works in real installations. It includes control functions, wiring reference, and key technical parameters. The guide also explains model code meanings, project limits, and possible customisation. Typical installation questions are also answered.
Key Functional Highlights
(This section explains the core control functions and their practical value.)
1. Temperature Control for Electric Heating Systems
The thermostat measures room temperature using its built-in sensor. It switches the electric heating output according to the setpoint. This control method keeps the electric heating system stable and avoids unnecessary power consumption.
2. Weekly Programming for Energy Management
The thermostat allows users to set different temperatures during the day. This programming function matches heating demand with daily routines. It helps the electric heating system maintain comfort while reducing electricity waste.
3. External Floor Sensor Protection
The external sensor measures the floor temperature in the heating layer. It prevents the electric heating surface from overheating. This protection improves safety and extends the service life of the electric heating installation.
4. Wi-Fi Remote Control
Wi-Fi connection allows the thermostat to work with a mobile application. Users can adjust temperature and schedules remotely. This makes the electric heating system easier to manage in homes and apartments.
If Wi-Fi is not required, one may refer to this electric heating thermostat instead (HTW-WF11-16A1).

Project Fit & Customization
(This section explains where the product can be used, its limits, and OEM/ODM options.)
This electric heating thermostat is designed mainly for electric underfloor heating control. It is not suitable for systems requiring BMS integration, such as Modbus. It also does not support direct valve control or fan coil operation.
Despite these limits mentioned above, functional customisation can be discussed for project needs. Communication interfaces or control logic adjustments may be possible depending on requirements. Our engineers can review project conditions before confirming any ODM modifications.
OEM services are also available for branding requirements. This includes logo printing on the thermostat, colour adjustments, customised labels, and packaging. Such OEM options are commonly used for distributors and project suppliers.

Frequently Asked Questions
Q1. Can this thermostat control other heating systems besides electric heating?
This thermostat is mainly designed for electric heating systems. It uses a 16A line voltage output, which is suitable for electric underfloor heating rather than valve-based heating systems.
Q2. Is the external sensor required for installation?
The external sensor is recommended for electric heating floor systems. It measures floor temperature and helps prevent overheating of the electric heating layer.
Q3. Does the thermostat require internet connection to operate?
No. The electric heating thermostat can work normally without internet. Wi-Fi is only needed when users want remote control through the mobile application.
Q4. What is the minimum order quantity and can I order samples?
Yes, thermostat samples are available for testing. The usual minimum order quantity is about 300 units, though smaller trial orders may be discussed depending on the project.
Q5. How can I place an order?
Please contact us to confirm the thermostat model and specifications. After confirmation we will provide a proforma invoice. Payment supports TT, PayPal, Visa, and other methods.
Q6. How will the products be shipped?
Door-to-door courier delivery is commonly recommended and usually takes about seven days. Air freight also takes around seven days, while sea freight normally requires more than one month.
