Wiring Diagram
Link485 connects chiller and AHU controllers over RS-485 to a wireless gateway.
Case Study: Rooftop Plant
Wireless retrofit with no downtime
Plant team retrofitted monitoring to existing plant using Link485. Dashboards showed kW/ton and alerted on abnormal conditions without any new riser cabling.
