Navien’s NaviLink Wi-Fi control system allows for remote access for all the company’s tankless water heaters, combi-boilers and gas condensing boilers through Wi-Fi control and mobile application. The system can report and monitor diagnostic data through the companion app along with error code notification. It is capable of reporting: DHW and space-heating set temperatures; current DHW temperature; DHW flow rates; inlet water temperature; total DHW consumption; average firing rate; cumulative gas consumption; and on-demand activation tracking.
