View and clear Installer Alerts
NOTE − Service alerts remind users to service filters, humidifier pad, UV light and
PureAirt Air Purification system and are not shown in the installer’s menu.
From the user’s home screen, press and hold the Lennox" logo in the bottom
right corner of the thermostat to access the installer program. Press yes
when asked if you want to proceed. The installer screen opens at the sys-
tem and device alerts" screen (figure 24A).
The left side of the "system and device alerts" screen shows a list of each
communicating device discovered in the system and check boxes for select-
ing each device. Or, you may use buttons to the right of the System Devices
list to select all (or deselect all). After something has been selected; use
view active to list all active alerts for selected devices. If there are no alerts,
the display will show There are no new alerts that require service". If there
are alerts, these are stored for recall but only one alert will appear in the box
at a time (see figure 24B). Use the next button to advance through all the
alerts. If only one alert is present, the next button will not appear.
Alerts may pop up on the screen during setup. Details of all active alerts can
only be accessed through the installer’s screens. To view all alerts present at
any time, press the alerts button. System setup / Diagnostics is complete"
(figure 24B) appears; close it and the Select devices to view alerts screen
(figure 24A) appears.
Use view cleared alerts to list previously active alerts that were cleared by
the device or installer. Until at least one alert has been cleared by the device
or the installer, the message There are no new alerts that require service"
will be displayed.
The first alert will be displayed in the alert screen (figure 24B), in order of:
1. red alert icon
2. yellow alert icon (service)
A red alert icon identifies a system or device issue that can prevent the sys-
tem from working properly or at all, and if allowed to run, could cause dam-
age to the system. The issue raised by the alert must be addressed and
corrected before clearing the alert!
Press clear (figure 24B) to clear a red alert. The alert will be stored in the
cleared alerts" file. If an alert cannot be cleared, revisit the alert issue and
make repairs accordingly.
