condition, if the burner resumes normal operation, the screen
will toggle the last fault and its cause for five days (longer du-
ration if control is not wired for constant power). This feature
is designed to allow the service technician to easily see what
caused the condition in the event the homeowner reset the
control prior to his arrival. The screen will alternate between
displaying what the last fault was and displaying how to clear

Lockout: If lockout occurs, the screen turns on, the fault icon

then release. NOTE: Recycling power to the control will not
reset it from it from a lockout condition.
Two fault conditions result in an immediate lockout. These
include; Flame detected during pre-purge and flame failure
during Trial for Ignition. All other faults will result in a Recycle
(unless the Allowed Recycles is set to 'None' in the Set-up
Menu). A Recycle results in the burner shutting down for 60
seconds then resuming operation in Standby (if there is no
Call for Heat) or initiating the Operating Sequence above (if
there is a Call for Heat).
Latch-up: If the control locks out 3 times during a single Call
for Heat, Latch-Up will be displayed on screen.
To Reset the control after latch-up, press and hold the red
Reset button for 30 seconds. WARNING: Only a qualified
service technician should attempt to reset the control
after latch-up. The problem that caused the repeat lock-
outs must be corrected before returning the burner to
normal operation. NOTE: Recycling power to the control will
not reset it from it from a latch-up condition.
