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.

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 temperature is greater than it, the system
passes to Wood, otherwise it will keep working with Pellet, power is not fixed to
PA29
and
no more controls for transition are carried out, unless the door is open (and then closed). In
that case, the system fixes again the power to
PA29
, starts counting
T71
and, when this
timer expires, checks the thermostat
Th68
: if Exhaust temperature is greater than it, the
system switches to Wood mode. When
T71
timer expires, working power is no more fixed,
while
Th68
thermostat is still monitored.
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
).
Now the system keeps working in Pellet mode (with not fixed power) until the Door is open,
and consequently closed. That condition lead the system to fix the power at PA29 and
makes the timer
T71
start. When it expires, the
Th68
thermostat is monitored: if exhaust
temperature is greater than it, the system switches to Wood, otherwise it will keep working
with Pellet. When T71 expires, working power is no more fixed, while
Th68
thermostat is
still monitored.
For the
Th68
thermostat control, the opening / closing of the door can take place both in
Wood or Pellets phase.
