Milesight UC711 Smart HVAC Controller

Milesight UC711 LoRaWAN HVAC Controller

The Milesight UC711 is a LoRaWAN® HVAC controller designed for remote monitoring and control of 24VAC heating and cooling systems. It supports PTAC systems, AC and furnaces, and heat pumps, and can operate with the Milesight WT401 wireless thermostat through Bluetooth.

UC711 provides Heat, Cool, and Auto temperature control modes along with Low, Medium, High, Auto, and Circulate fan modes. Built-in LoRaWAN®, Bluetooth, and NFC connectivity simplifies remote control, device configuration, and integration with building management applications.

When used with a Milesight LoRaWAN® gateway with BACnet enabled, UC711 can also integrate with BACnet/IP building management systems for monitoring and supported configuration control.

UC711 is ideal for HVAC control in hotels, commercial buildings, offices, apartments, and other facilities using compatible 24VAC HVAC equipment.

Important: UC711 is designed for 24VAC HVAC systems only. Do not connect the controller to high-voltage or high-current systems.
