Hours Run Meter
Both XEL and XELH ventilation units incorporate an hour run meter that allows the installer to measure the actual running time of
the fan after installation. The meter records continuous power supply on time and displays this via an on-board red LED that always
flashes to indicate the total number of hours the supply has been on.
LED flash sequence to indicate hour run:
•
LED off for 2 seconds to indicate the start of the count, then:
•
0 to 2000 hours: LED on for 1 short flash (0.5s on / 0.5s off)
•
2000 to 3000 hours: LED on for 2 short flashes
•
3000 to 4000 hours: LED on for 3 short flashes
•
4000 to 5000 hours: LED on for 4 short flashes
•
5000 to 6000 hours: LED on for 5 short flashes
•
6000 to 7000 hours: LED on for 6 short flashes
•
7000 to 8000 hours: LED on for 7 short flashes
•
8000 to 9000 hours: LED on for 8 short flashes
•
9000 to 10000 hours: LED on for 9 short flashes
•
Each 10000 hours is indicated by 1 long flash (2.0s on / 0.5s off)
