Accessory Maintenance Pop-Up Messages
Accessory Pop-Up messages remind you when it's time
for accessory maintenance. There can be up to five messages,
depending on the accessories installed with your system:
- Replace UV Lamps
- Change Humidifier Pad
- Clean Air Filter - EAC
- Clean or Replace Air Filter
- Clean Ventilator Filter
REMIND LATER: Pressing the LEFT button to select
REMIND LATER will cause the accessory status message to reap-
pear in seven days. The message will not reappear at the end of
the seven-day period if the usage indicator has been reset.
DISMISS NOTICE: Press the RIGHT button to DISMISS NOTICE
and reset the accessory maintenance reminder. The reminder will
reappear at the next maintenance cycle.
The maintenance cycle for the humidifier, UV lamp and EAC is
based on time and may be set by your installer. The defaults are
as follows:
EAC: 3 months of operation
Humidifier: 12 months of operation
UV Lamp: 12 months of operation
Ventilator Filter: 3 months of operation
The maintenance cycle for MEDIA or EAC + MEDIA is based on
actual airflow restriction which is automatically detected by the
system.
