Filter Service
The Filter Service screen will show the accumulated Filter Runtime hours as well as the Service Interval that will be used
to trigger a Filter Message. Any type of HVAC operation that causes the HVAC system fan to run will cause the Filter
Runtime value to increase.
When the Runtime hours equals the Service Interval hours, the Red LED will flash along with a “Filter” message to remind
you to replace the filter. Once the filter has been replaced, press the Reset button to reset the Filter Runtime value to zero.
