Other Functions
6.1
Automatic Combustion Power
In the Combustion Power setting, the user can set the Automatic modality [A]. The work power is
automatically selected according to the Water Temperature and the value of Boiler Thermostat:
Water Temperature ≤
Boiler Thermostat
–
d08
the system goes to the maximum available
Combustion Power
Boiler Thermostat
–
d08
< Water Temperature <
Boiler Thermostat
the Combustion Power
decreases reaching the Boiler Thermostat
Water Temperature ≥
Boiler Thermostat
the system goes to Combustion Power 1 if
A06
=0
or to
Modulation Power if
A06
=1
Example:
Boiler

=75 °C,
d08

6.2
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
.
6.3
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.
6.4
System Maintenance 2 Function
When the system exceeds the working hours set by the parameter
T67
it is notify 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 push the button
P5
. To disable this feature set
T67
=0.
6.5
Calibration Step
The user can correct the Auger’s times On and the Combustion Fan Speed with step –5÷5. The parameters
and
P15
and
P16
are the percentage value of the single correction step and is applied on the Work default
values.
Calibration Combustion Fan example:
P16
=5%, Step= +3
Default Values
U03
=1000
U04
=1200
U05
=1400
U06
=1600
U07
=1800
U11
=900
Calibrated Values
U03
=1150
U04
=1380
U05
=1610
U06
=1840
U07
=2070
U11
=1030
The calculated values are bounded by parameters
P14
and
P30
.
Calibration Auger example:
P15
=10%, Step= -1
Default Values
C03
=2,0
C04
=3,0
C05
=4,0
C06
=5,0
C07
=6,0
C11
=1,0
Calibrated Values
C03
=1,8
C04
=2,7
C05
=3,6
C06
=4,5
C07
=5,4
C11
=0,9
The calculated values are bounded by parameters
P27
and
P05
.
6.6
Output V2 Management
It is possible to configure the Output V2 (pins 5-6) setting the parameter
P44
. If this output isn’t used set
P44
=0.
6.6.1
Pellet Safety Valve or Auger 2
If the parameter
P44
=1 the output is configured as a Pellet Safety Valve or Auger 2.
