i-Vu® Link

Seamless integration of Carrier Comfort Network controllers into the i‑Vu® platform
The i‑Vu® Link (CIV‑L) bridges Carrier Comfort Network (CCN) controllers with the i‑Vu® Building Automation System, enabling centralized monitoring, scheduling, trending, and control across multiple CCN networks through a single web‑based interface.

i-Vu® Link

Network device used to integrate Carrier and non-Carrier equipment with i-Vu®
The i-Vu Link module allows you to integrate other manufacturers’ equipment into the i-Vu Building Automation System. Support for BACnet, Modbus®, and LonWorks® protocols is standard, making it easy to tie in equipment such as VFDs, boilers, and lighting in order to complete your Carrier system. Each i-Vu Link module supports up to 500 third party BACnet, Modbus, or LonWorks points.

i-Vu® Link

BACnet Routing Between i‑Vu and CCN
