Auxiliary Output Management
It is possible to configure the Auxiliary Output (pins 19-20-21) setting the parameter
P48
. If this output isn’t
used set
P48
=0.
It is a free contact output
.
6.7.1
Pellet Safety Valve or Auger 2
If the parameter
P48
=1 the output is configured as a Pellet Safety Valve or Auger 2.
It is necessary to
supply the output
. See section 6.6.1 to see how it works.
6.7.2
Load Pellet Engine
If the parameter
P48
=2 the output is configured as a Load Pellet Engine.
It is necessary to supply the
output
. See section 6.6.2 to see how it works.
6.7.3
Output Under Thermostat
If the parameter
P48
=3 the output is managed by
Th56
Thermostat.
It can be used to give consent to an external system (e.g a boiler) or, if it is supplied as shown upon, to
control a valve or other device. If water temperature is greater than
Th56
it is guaranteed a voltage
between pins 19-21, otherwise it is guaranteed a voltage between pins 19-20.
6.7.4
Cleaning Engine
If the parameter
P48
=4 the output is configured as a Cleaning Engine.
It is necessary to supply the
output
. See section 6.6.4 to see how it works.
6.8
Periodic Cleaning of Brazier
Periodical Cleaning of brazier occurs in Run Mode for a time
T08
with a repetition time equal to
T07
timer.
During the cleaning phase the, Exhaust Fan goes to at
U09
power and the Auger at
C09
.

Primary Air Flow Sensor
The Control Board is designed for reading a Combustion Air Flow Sensor. Estimating the air flow speed of
the inlet it can adjust the scope of the system. It works in Run Mode and Modulation states. For the correct
use of the system do the following:
1.
Supply the System, switch on it and leave it works, with air flow sensor disabled (parameter
A24
=0). In
Run Mode and Modulation states monitor the air flow velocity for each power of the system.
2.
Once found the optimum air flow velocity values for each power of the System, start to configure the air
flow regulator setting:
FL22
,
FL23
,
FL24
,
FL25
,
FL26
,
FL27
,
FL30
the Air flow minimum speed allowed for each
power
FL42
,
FL43
,
FL44
,
FL45
,
FL46
,
FL47
,
FL50
the Air flow maximum speed allowed for each
power
T19
the time how often to regulate the combustion (short is this time, less readings will be done
by the system).
T20
waiting time with regulator fixed on the minimum or the maximum, before to go to regulate
another output or before to go in regulation error.
T80
Waiting Time before starts the first regulation (Stabilization of the System)
A24
to set which kind of output has to be regulated:
0
=Regulator Disabled;
1
=Combustion Fan
regulation;
2
=Combustion Fan+Auger regulation;
3
=Auger regulation;
4
=Auger+Combustion
Fan regulation;
5
=Regulator not present;
