Aqara Floor Heating Thermostat W500 (UT-A01D) - Zigbee & Thread Thermostat

Precise and energy-saving control

Floor thermostat AQARA W500 is an advanced smart thermostat designed for both electric and water underfloor heating. By combining the latest technologies and intuitive operation, it delivers maximum comfort while effectively reducing energy consumption, saving on heating costs. It supports Thread and Zigbee wireless protocols, enabling seamless integration into popular smart home ecosystems such as Apple Home, Google Home and Amazon Alexa.

After connecting to the Aqara Zigbee hub, users can discover exclusive Aqara features for an even richer smart home experience.

AQARA Floor Heating Thermostat W500

The thermostat is designed for installation in standard European boxes and has a clear LCD display for a clear status display. It is equipped with a built-in temperature and humidity sensor and allows the connection of an external wired floor temperature sensor (NTC).

With scheduling, preset modes, on/off timer, remote control and real-time energy consumption measurement, the W500 contributes to higher energy efficiency and lower heating costs. In addition, it supports the Matter ecosystem for broad compatibility or can be used with the Aqara Home app for seamless integration of smart devices.

Key features

• Backlit LCD display: The thermostat has a backlit segment LCD display, designed according to European and Russian box standards for easy installation and readability.
• External NTC sensor support: Compatible with external wired floor temperature sensors (NTC), allowing selection between 10KΩ, 50KΩ or 100KΩ sensors according to the type of heating.
• Thread and Zigbee dual protocol: Thread support for easy access to Matter-compatible smart home platforms without the need for an Aqara hub, while Zigbee enables exclusive features in the Aqara Home app and compatibility with existing Aqara hubs.
• Connection with temperature and humidity sensors: Connection with Aqara temperature and humidity sensors via the app for accurate temperature measurement and better heating control.
• Climate sensor integration: Wireless control via the W100 climate sensor allows for easy remote temperature adjustment and mode switching.
• High load capacity: Designed to handle up to 16A resistive load (3600W), supporting a wide range of underfloor heating systems.

Flexible ecosystem integration with dual protocol support

Support for both Thread and Zigbee protocols offers exceptional flexibility. Thread mode allows the thermostat to connect directly to Matter-compatible ecosystems, ideal for users looking for easy integration without the need for additional hubs.

Zigbee mode reveals the full functionality of the Aqara Home app, including intelligent scheduling, temperature calibration, and energy consumption monitoring. This dual-protocol system allows you to customize your smart heating to your personal preferences and current smart home.

Multiple control methods for easy temperature control

Control your underfloor heating your way – using physical buttons, full-featured remote control via application Aqara Home or voice commands through major smart assistants like Alexa and Google Assistant. The device supports flexible scheduling of up to seven heating periods per day for every day of the week.

Scheduling takes place locally in the thermostat, so the heating runs without interruption even if the internet or connection to the hub goes down.

Smart energy-saving features

Monitor your heating energy consumption in real time and evaluate daily or monthly consumption for better efficiency. The thermostat automatically pauses heating when a window is open, which is detected by Aqara door/window sensors, preventing unnecessary energy consumption.

Detects rapid temperature drops without sensors and activates 30-minute pause to save energy. These smart features help reduce heating costs without compromising comfort.

 

Precise temperature control with multiple sensor inputs

Achieve maximum comfort with highly accurate temperature control. The W500 uses data from its internal sensor, an external wired NTC floor sensor, or Aqara temperature and humidity sensors located throughout the house. The ±5°C calibration allows you to fine-tune the thermostat to your environment and prevent differences between the measured and actual room temperature.

Custom temperature buffer values ​​(0.5–3°C) reduce heating on-off cycles, which promotes a more stable environment and extends the life of the equipment.

Strong security and durability features

Safety comes first with the W500. It has floor material protection that prevents overheating of sensitive floor types, an anti-frost function that activates heating around 5°C to prevent freezing, and automatic shutdown in case of overheating or overload for safe and reliable operation of the device.

Practical automation scenarios for everyday comfort

Easily set up heating automation with preset modes like “Morning heating” which will raise the temperature to 22°C at 6:30am on weekdays for a comfortable start to the day. “Energy saving when absent” mode will turn off the heating after 30 minutes without movement, preventing waste. “Underfloor heating after shower” mode will raise the temperature in the bathroom to 25°C when the humidity reaches 70%, for a pleasant environment after a shower.
