Display Indicators
Several	situations	or	events	are	indicated	in	normal	operation	by	blinking	display	indicators	or	segments	in	the	display:
Flashing On Indicator:		This	means	that	the	stove	is	in	the	“Start	Up”	state	waiting	for	either	a	3	minute	time-out	to	
begin	burning	or	for	the	stove	to	reach	the	warm	temperature	whichever	comes	first.
Flashing Off Indicator:		This	indicates	that	the	stove	is	in	the	“Shutdown”	state	waiting	for	the	OFF	button,	or	for	a	15	
minute	period	after	the	stove	was	turned	off,	or	for	the	stove	to	cool	down,	or	for	the	door	to	be	closed.
Flashing dash in Heat Range Display:		This	indicates	that	the	stove	is	in	the	normal	run	mode	and	is	ramping	from	
the current heat range setting to the target heat range setting. Once the ramp is complete, the dash will stop flashing.
For	ramping	from	heat	range	1	to	5,	the	default	time	is	12	minutes	(with	a	90	second	ramp	time).
Flashing Automatic Mode Indicator:		This	indicates	that	the	stove	is	in	normal	operation	and	is	running	in	the	automatic	
mode.		However,	either	the	Draft	Fan	or	Auxiliary	setting	is	manually	configured.
Flashing Draft Fan Setting Indicator:		This	indicates	that	the	stove	is	in	normal	operation	and	that	the	vacuum	sensor	
detects a loss of pressure either because the door is open or because there is a negative pressure in the room with
respect	to	the	exhaust.
Flashing Aux Indicator: 	This	indicates	that	the	ignitor	is	on	during	the	lighting	stage.
Quickly (changes twice per second) Flashing Heat Range Setting Indicator:		This	indicates	that	the	stove	is	in	
normal	operation	and	that	an	over-temperature	condition	exists	causing	the	fuel	to	stop.
Slowly (changes once per second) Flashing Heat Range Setting Indicator: This	indicates	that	the	stove	is	in	a	cut	
back	condition	in	an	attempt	to	prevent	an	over-temperature	shutdown.
Factory Defaults
To	return	the	control	to	its	original	factory	default	settings,	press	and	hold	the	AUX	UP	and	AUX	DOWN	buttons	together	
for three seconds.
