start the search for AC power.
2. When AC power is detected, the AC light
remains on.

or when AC power is lost in AC Manual mode, the
controls:
1. Display the "no AC" fault code.
2. Sound the audible alarm. The alarm is an
intermittent beeping tone. Pressing the MODE
pushbutton silences the alarm.
3. Record and store the "no AC" fault in diagnostics
nonvolatile memory fault history.

AC Power Restored

When AC power is restored, the controls:

however, the recorded fault history will not be

LP Manual Mode

In the LP Manual Mode, LP gas is the only heat
energy source selected by the controls. When the
controls shift to LP Manual mode:
1. The LP light flashes and the controls
start a 30 second trial-for-ignition.
2. When the controls sense a flame
the LP light remains on.

second trial-for-ignition or the flame goes out, the
controls:

2. Set "gas lock-out." See NOTE 3 below.
3. Sound an audible alarm. The alarm is an
intermittent beeping tone. Pressing the MODE
pushbutton silences the alarm.
