Change Power Delay
When the system exits from the Ignition and goes in Run Mode, the Combustion Power, starting from the Power 1,
reaches the target one increasing the value with the delay time as the timer T18.
The other manual or automatic power changes are managed and actuated with the delay time as timer T17 .
System Maintenance 1 Function
When the system exceeds the working hours set by the parameter T66 it is notify the user to contact the service
to verify the proper functioning of the system. The display shows the message 'Service' and the system goes in
Block. To unblock it is necessary to reset the counters. To disable this feature set T66 =0.
To enable this feature set
T66
>0
System Maintenance 2 Function
When the system exceeds the working hours set by the parameter T67 it is notified to the user to clean the boiler
or the stove. The display shows the message 'Clean' and the system gives out an acoustic signal periodically. To
stop signalling enter the menu “Reset Service”. To disable this feature set T67 =0.
Extinguishing in Ignition Phase
When the system is turned off during the Ignition phase (after Preheating phase) by an external device or by
internal chrono, it really goes in Extinguishing when it enters the Run Mode at the end of Ignition. On display
appears the message "Block Ignition".
In Combi 2 modality if the system is turned off ( also with manual control):
 PA23 =0 the System does the extinguishing if exhaust temp. > Th64 or if T71 is expired. In the first case the
extinguishing is performed in Wood modality, in the second case in Pellet modality. Furthermore in this case, if
exhaust temp. > Th68 the extinguishing switches to Wood modality.

PA23 = 1. The System, when T71 expires, checks exhaust temperature. If it’s greater than Th64 extinguishing
is performed in Wood mode, otherwise in Pellet mode. , the system goes on with the extinguishing in pellet
modality. If exhaust temperature is > Th64 the system starts a checking procedure, similar to that of Wood
transition described in section 6.3. In this case, the system can switch to Wood extinguishing. Furthermore in this
case, if exhaust temp. > Th68 the extinguishing switches to Wood modality
If it occurs any error, the system goes immediately in Extinguishing with error.
If the P2 button is pressed it is possible to get immediately the system in Extinguishing or in Ignition.
Automatic switch off function
If the parameter A40 =1 and the functioning is in Pellet modality the system, after T84 minutes in Run Mode,
Modulation and Standby-Maintenance goes in Recover Ignition.
Supply Voltage Lack Management
In case of supply voltage lack, the system saves the most important functioning data. With the return of the supply
voltage, the system evaluates the saved data and, according to parameter
A53
we have:

A53
=0
o
If the lack is less than T88 the system returns to the state in which it was previously
o
If the system was in a On state and the lack of voltage is between T88 and T89 the system goes in Recover
Ignition, if it is in Pellet modality; it goes in Run Mode if in Wood modality
o
In case of lack of Supply Voltage for a time greater than
T89
the system goes in Block with error message Er15

A53
=1
o
If the lack is less than T88 the system returns to the state in which it was previously
o
If the system was in a On state and the lack of voltage is greater than
T88
the system goes in Recover Ignition,
if it is in Pellet modality; it goes in Run Mode if in Wood modality
Auger Feeding in Wood Modality
When the system is in Wood modality and in the states Run Mode and Modulation is possible to feed the Auger
and download pellets in the brazier.
If the flue gas temperature is greater than Th13 thermostat, the Auger is off for the time T53 and it is on for the
time T54 ; if a configurable output is set as the Safety Valve ( P44 or P48 or P36 =1) the Auger is turned on only
at the end of time
T40
.
If the Combustion Fan was off, it is turned on at the speed
U12
, otherwise it continues to work on the power to
which it was working. If the fuel in the tank is run out, the function is disabled.
