DISPLAYS
Display Description Explanation
IGNITION
Indicates the pellet ignition phase Phase in which pellet combustion is triggered
PUMP ANTILOCK
Indicates the function that prevents pump
block.
This function activates every 48 hours by activating all plant
pumps/electro-thermal controls.
SYSTEM ANTIFREEZE
Indicates the system anti-freeze function.
If the C.H. anti-freeze function is not su cient to stop the lowering
of the water temperature, the system anti-freeze function
activates, which ignites the C.H. The C.H. and the pump/electro-
thermal controls will stay on until they reach a determined
temperature level.
PUMP ANTIFREEZE
Indicates the pump anti-freeze function.
If the temperature read by some of the C.H. probes falls below a
determined temperature value the circuit board will activate all
of the outputs relative to the pumps/electro-thermal controls.
Pumps/electro-thermal controls will stop when the temperature
rises.
WAIT FOR CLEAN.
A new ignition is attempted when the boiler
has just been switched o (normal switch-o
or caused by an alarm).
When the stove switches o (normal or caused by an alarm) it is
necessary to wait until it cools down completely, therefore clean
the brazier. Leave the boiler completely o and cold for at least
15 minutes before switching it on again.
ECONOMY T. WAIT
The C.Heat. is in “HOFF” status and the
ECONOMY SET has been set
The re-ignition of the C.H. is restricted by the temperature set in
the
ECONOMY SET.
START
Indicates the pellet combustion phase. Indicates the transition phase between ignition and working.
CHECKUP
Indicates the control function performed by
the boiler.
This function activates every time current is removed and re-
applied from the boiler in the
OFF, status. The machine performs
a particular analysis cycle to check the correct functioning of al
of its parts.
ANTIBACTER. CYCLE
Indicates the antibacter. function.
This function only activates with boiler on and allows to neutralise
the bacteria of Legionnaire’s disease.
CORRECTION O2
Indicates the combustion correction
function.
This functioning cycle uses the value read by the lambda probe
in order to correct imperfect combustion. At the end of the
correction cycle the boiler will go back to normal functioning
HOFF
The temperature of the water has exceeded
the set threshold by more than 5°C.
The water has reached a temperature of
85°C.
On lowering of the water temperature (5° below the set threshold)
the machine will re-start in automatic mode.
WORKING
Indicates the normal functioning status of
the boiler
The boiler works to satisfy the plant requests.
OFF
Indicates the o status of the boiler
In this status the boiler is completely cold and waiting to be
ignited; this can take place in di erent ways in relation to the
boiler setting used.
LOWER DOOR OPEN
The lower door is open Check closure of the lower door
CONDUIT CLEANING
Indicates the pellet load conduit cleaning
function caused by a temperature increase
inside the conduit
Wait for the complete conduit cleaning cycle until the boiler
returns to normal functioning. If this is not the case, the C.H. will
display the “
PELLET CONDUIT ALARM “
AUTOMATIC
CLEANING
Indicates the boiler automatic cleaning
function
This function envisions a complete cleaning cycle that includes
switch o and switch on of the boiler.
FINAL CLEANING
The boiler was switched o through button
1(esc)
At the end of this cleaning and cooling cycle the boiler will pass
to the
OFF status
COOLING BLACK OUT
No current on the main power supply for a
period longer than 10 seconds
After the complete switch-o cycle the stove will re-ignite
automatically
SAFETY Z1
Indicates the safety for removal of heat
accumulated in the boiler
This function activates if the water temperature inside the boiler
exceeds 87°C: the pump/electro-thermal control relative to zone
1 is enabled even if there is no request for heat. Stop occurs when
the temperature drops
AUTO BLOW
Indicates the burner automatic blow
function
The burner automatic blow is accompanied by the on the display.
At the end of the cleaning cycle the boiler will go back to normal
functioning
COR. PEL.
Indicates a high temperature on the fumes
It is not in alarm conditions. The C.H. intervenes automatically to
lower the temperature level, continuing its normal work
