Main Menu - User Settings - Maint Service
The Maintenance Service screen will show the accumulated Heat and Cool Runtime hours as well as the
Service Interval that will be used to trigger a Maintenance Message. Any HEAT or COOL type of HVAC
operation will cause the respective Runtime values to increase.
When the combined HEAT and COOL Runtime hours equals the Service Interval hours, the Red LED will
flash along with a “Maint” message to remind you your HVAC system may require periodic maintenance.
Pressing the Menu button will take you to the Filter Service screen. The Reset button can be pressed and
the HEAT and COOL Runtime values will be reset to zero.
The Service Interval period can be changed using the +/- buttons.
