The filter reminder will alert you of the need to replace the filter after between 5-19 months depending of usage.
The filter counter integrates both elapsed time and fan run time.
Every minute FilterCounter += (33 + percentageFanSpeed)
Overdue threshold 35,000,000 units = (60x24x365x2 * 33)
Reminder threshold 28,000,000 units = (at 80% of life)
When the overdue period has elapsed the message will escalate ( see filter display screen for further details.)
If the fan is never used:
- the reminder will appear after 19months.
-overdue display will appear after 24 months.
if the fans run 100% for 24 hours a day, 7 days a week:
- the reminder will appear after 5 months.
-overdue display will appear after 6 months.
