UC722 - VRF System Controller - Milesight

Centralize VRF control

The UC722 brings up to four VRF systems together in a single controller. Its independent channels control the outdoor units and their indoor units from a common architecture. In an office building, hotel, or multi-room site, start-up, mode, setpoint, and ventilation controls are organized into time schedules and zone groups. The manager thus has a single point of access to operate multiple installations.

Connect the air conditioning to the BMS

Two Ethernet ports and an RS485 interface connect the controller to the building management system. Modbus TCP, Modbus RTU, and JSON facilitate the exchange of statuses and commands with supervision applications. The integrated web interface is used to configure the channels, while the LCD screen and status indicators provide direct on-site monitoring. Each channel has its own configuration to organize the building's different VRF zones.

Install and operate on site

The UC722 operates on 12 to 24 V DC and is mounted on a DIN rail or on the wall. Its commissioning brings together the connection of the outdoor units, the assignment of the channels, and the configuration of the BMS interface. Group controls and schedules structure daily operation. Parameter monitoring, remote diagnostics, and the detection of abnormal operating times support the maintenance of the VRF installations.
