Milesight WT401 – LoRaWAN Wireless Smart Thermostat Temperature Control

Milesight WT401 Smart LoRaWAN Thermostat

Transform conventional climate control into an intelligent automated system with the outstanding WT401 Smart LoRaWAN Thermostat.

This premier smart thermostat provides seamless local and remote control over HVAC systems, including furnaces, air conditioners, heat pumps, boilers, and PTAC units. Operating across standard LoRaWAN® frequency bands, the WT401 combines an intuitive 2.7-inch black-and-white e-ink display with tactile control buttons and integrated environment sensors to deliver comprehensive room climate monitoring. Built with flame-retardant materials, an anti-theft installation design, and a child lock feature, it ensures safe and reliable long-term operation.

Seamlessly integrating with Milesight LoRaWAN® gateways and leading LoRaWAN® network servers, the WT401 supports both Class A and Class C operation modes for flexible energy management and real-time responsiveness. When paired with the Milesight IoT Cloud platform or Building Management Systems (BMS), it enables remote temperature scheduling, central HVAC control, and automated scene synchronization triggered by occupancy.

The integrated passive infrared (PIR) sensor offers smart occupancy detection to automatically optimize heating and cooling when spaces are vacant, while the embedded MEMS sensors measure ambient temperature and humidity in real time.

Ideal for diverse indoor applications such as smart offices, hotels, educational institutions, retail stores, and commercial facilities, the WT401 is your go-to solution for intelligent climate control and building energy efficiency.

Key Features

• Intuitive E-Ink Display: Clear 2.7-inch display shows environment temperature, humidity, fan mode, and system status clearly.

• Built-in PIR Occupancy Sensor: Detects human presence within 6 meters to automatically trigger energy-saving temperature plans.

• Integrated Temperature & Humidity Sensors: Continuously monitors room status with high accuracy ($\pm0.2^\circ\text{C}$ temperature, $\pm2\%$ RH humidity).

• Multiple Operating Modes: Supports Heat, Cool, Auto, and Emergency Heat modes alongside flexible fan settings (Low, Medium, High, Auto, On, Circulate).

• Effortless NFC & Bluetooth Configuration: Simplify setup and parameter adjustment in seconds using a smartphone with the Milesight ToolBox app.

• Versatile Power Options: Flexible deployment supporting replaceable lithium batteries (up to 5+ years battery life), AC/DC 24V wiring, or USB Type-C power.

Enhanced Safety Features:

The WT401 includes a built-in child lock and anti-theft mounting design to prevent unauthorized local tampering, along with over-temperature protection that automatically safeguards the screen in extreme thermal conditions.

Flexible Power & Connectivity:

By supporting multiple power sources—including 24V AC/DC, USB-C, and battery power—the WT401 can be easily deployed in retrofit installations without hardwiring or integrated into permanent power infrastructure.

Milesight Smart Climate Automation offers:

• Reliable Data Transmission: Long-range wireless coverage reaching up to 15 km in line-of-sight conditions and 2 km in urban spaces.

• Multicast Capability: Group multiple thermostats together to synchronize temperature setpoints across entire floors or zones simultaneously.

• Automated Scheduling: Program up to 8 distinct local working plans or set flexible weekly routines to minimize HVAC energy waste.
