COMBI MODALITY
By parameter
P11
you can configure user-selectable modes of operation for the current system:
Only Pellet Mode (
P11
=0)
In this configuration the system can only operate at Pellet Mode and in the User Menu, the submenu functioning
isn’t present.
Only Wood Mode (
P11
=1)
In this configuration the system can only operate at Wood Mode and in the User menu, the submenu functioning
isn’t present.
Wood/Pellet Mode (
P11
=2)
In this configuration the system can operate both Pellet and Wood Mode, but not at the same time.
Through the submenu functioning of the User Menu you can select the desired operation.
Combi Mode 1 (
P11
=3)
In this configuration, the system can operate in Pellet, Wood and also in combination. Through the submenu
functioning of the User Menu you can select the Pellet,Wood or Combi Mode (on display appears the symbol ).
The combi mode 1 allows to turn on again automatically in pellet mode, when the wood in the brazier is finish.
When the system is in Pellet mode, the combi mode is deactivated.
When the system is turned on, it starts in Wood Mode. If the exhaust temperature measured by the thermostat is
higher than the
Th13
is loaded timer
T21
; if later the temperature is lower than
Th13
for
T21
minutes the
system turn on again automatically in Pellet Mode.
For safety reason, the transition from wood to pellets is not allowed until the water temperature in the boiler is
higher than the
Boiler Thermostat
.
Combi Mode 2 (
P11
=4)
In this configuration, the system can operate in Pellet, Wood and also in combination. Through the submenu
Functioning of the User Menu you can select the Pellet,Wood or Combi Mode (on display appears the symbol ).
The Combi mode 2 turns on the system in Pellet mode and allows to burn the wood, and finally enter in Wood
Mode. When the wood is over the system goes in Pellet mode. This modality doesn’t turn off automatically, to
perform the Combi cycle again you must first turn the system off and then on again.
In mode 2 Combined the ignition of wood with pellets is carried out considering the parameter
P71
. If:
P71
≠4 and
P74
,
P75
,
P76
≠18 are considered thermostats
Th63
,
Th66
,
Th69
instead of thermostats
Th03
,
Th06
,
Th09
P71
=4 or
P74
,
P75
,
P76
=18 is considered thermostat
L01
If the system passes the phases of Ignition and Stabilization, comes up to speed and starts the timer
T71
. During
the time
T71
the system can only go in Safety or Modulation / Standby for Boiler Temperature according to the
parameter
A13
.
At the exit from Standby, the system resumes from Ignition phase, restarting the Ignition of Wood with pellets.
Depending on the value of the parameters
PA29
and
PA23
, the system will work in the following way:
PA29
= 0 and
PA23
=0
At the end of the
T71
time, if the exhaust temperature is higher than
Th64
thermostat, the system goes in Wood
Mode otherwise, at the end of the timer, keeps working with Pellet.
When the wood is over (exhaust temp <
Th13
thermostat) at the end of the
T21
timer, the system turns on again
in pellet mode automatically(the thermostats considered are
Th03
,
Th06
,
Th09
).
If during Pellet Mode after the end of the wood, the exhaust temperature becomes greater than
Th68
thermostat,
the system goes again in Wood Mode and the Combi cycle restarts.
Transition from Wood to Pellet is not allowed if Door input is Open.
PA29
= 0 and
PA23
=1
In this case, the Door input is used for the system transition to Wood.
Once the system came up to speed, at the end of
T71
timer, the thermostat
Th64
is checked: if exhaust
temperature is greater than it the system passes to Wood mode, otherwise it keeps working with Pellet. Here the
system kepps checking the thermostat
Th68
for the transition to Wood.
If the system successfully passed to Wood, once it finished (exhaust temperature lower than the thermostat
Th13
)
when the timer
T21
expires, the system turns on again with Pellet automatically (thermostats
Th03
,
Th06
,
Th09
).
The system keeps working with Pellet until the Door is open, and consequently closed. This condition starts the
timer
T71
and, from its expiring, the thermostat
Th68
is checked. If exhaust temperature is greater than it the
system passes to Wood, otherwise it will keep working with Pellet.
For the
Th68
thermostat control, the opening / closing of the door can take place both in Wood or Pellets phase.
PA29
≠ 0 and
PA23
=1
In this case, the functioning is managed only with door present. During ignition, once fully operational, the system
is brought to work to the fixed power
PA29
. At the end of the timer
T71
,
Th64
thermostat is checked: if Exhaust
