The Milesight Smart Thermostat WT201-868M/915M is a next-generation HVAC controller built on LoRaWAN® and Milesight D2D technologies, offering long-range, low-power, and robust wireless performance. Compatible with most 24VAC heating and cooling systems—including furnaces, air conditioners (2H/2C), heat pumps (up to 4H/2C with AUX), boilers, AHU, and PTAC units—it provides unmatched versatility for modern building environments.
Equipped with built-in temperature and humidity sensors using CMOSens® MEMS technology, the WT201 ensures high accuracy and fast response times. Its large 4.2-inch LCD segment display provides clear real-time visibility of room temperature, humidity, and system status, making it ideal for homes, offices, hotels, and commercial spaces.
With four temperature control modes (Heat, Emergency Heat, Cool, Auto) and three fan modes (Auto, On, Circulate), the thermostat delivers flexible climate management. Users can program up to 16 schedules per mode, allowing automated comfort settings tailored to occupancy and time of day.
Real-time monitoring enables instant alerts when sudden temperature changes occur, enhancing safety and protecting assets. The device supports cloud-based management, Milesight D2D ultra-low-latency control, NFC configuration, FUOTA firmware updates, and local storage of up to 1,000 historical data entries.
Integration with hotel room card systems helps minimize energy consumption, while compatibility with Milesight LoRaWAN® gateways, Milesight Development Platform, and BACnet ensures seamless integration into modern building automation systems.
