The upper and lower displays are used to view 

the various messages.

The upper display will show 

the word

and the igniter will light up to 

start the flame.

When the flue gas temperature 

is at 50° C (about 10 minutes) 

the heat stove will enable 

ignition: the top display will then 

read 

“FirE” 

while the bottom 

display will read 

“ON”

.

After this stage which lasts 

5 minutes approximately the 

top display will simultaneously 

show the heating power (e.g. 

“po6“

) and ambient temperature 

(e.g. 

“25C“

), while the lower 

display will show the system's 

flow water temperature. 

Control panel signals

Before  igniting  the  heat  stove  ensure  the  pellet 

tank is filled, the combustion chamber is clean, 

the glazed door is closed, the plug is plugged in 

and the switch at the rear is in position “1”.

The LED is on when parameter UT0 

1 in the menu is other than OFF, thus 

setting the weekly or daily program.

“SET”

LED

SYMBOL

The LED is enabled every time the 

pellets are being filled.

The  LED  flashes  when  the  panel

If the flame is not correctly ignited after 10 minutes, 

the heat stove locks down: the upper display will 

read 

“ALAR” and the lower display will flash the 

words 

“NO ACC”

: wait 10 minutes for the cooling 

cycle to be completed, open the door, empty the 

burn pot and proceed with a new ignition.

Heat stove Cycle On/Off

PLEASE NOTE:

In the event there should be repeated failed 

ignitions, but the pellets are fed properly, there 

might be an issue connected to breakage of the 

electrical igniter. 

In this case, while waiting for a technician to 

service it, the heat stove may be lit manually using 

solid fuel cubes (fire starters).

Do not use any flammable liquids for 

ignition. 

While filling do not let the pellet sack 

come into contact with the hot heat 

stove.
