RECONFIGURING SYSTEM
If any component of the HVAC system has been changed, e.g. replacing an outdoor sensor, reconfiguring the system
will be required.
1. To begin reconfiguring a system (after you have accessed the program from the Lennox logo [previous page]),
press the setup button (1, figure 36A). The “Start system configuration” screen (fig. 36B) will appear.
2. Press start (2, figure 36B) to proceed. The “Re-configure confirmation” screen (fig. 36C) will appear. This reminder
notes that system configuration may affect some existing device settings and prompts to confirm or cancel the
configuration process.
3. Press confirm (3, figure 36C) to continue system configuration; the screen will change to the system discovery
screen. At this point, the program goes through the same setup as the initial setup process which begins on
Page 3.
NOTE - “Compatible device found” screen (shown below) appears only when a device has been removed and replaced
with a compatible device.
