Operating Hours
Operating hours are the accumulative time since the LHX heat
exchanger is first connected to the EMX device and turned ON.
The EMX web interface displays the operating hours both for the heat
exchanger and its fans. Operating hour information is located in the
Statistics section of each heat exchanger page.
Below are the time units used for operating hours:
h: hour(s)
d: day(s)
For example, "3d 5h" means the total operating time is 3 days and 5
hours.

page specific to that heat exchanger opens in the right pane.
