Principle of operation
Work mode
Depending on the mode, the controller goes
through series of states, so it reaches the final state
for the mode. Changing the mode, makes the
controller enter sequence of states, guaranteeing the
correct power up or shutdown.
The boiler pump is always active, as long as the
conditions for its operation are met, independent of
the current mode. Exception of this rule is the case of
working DHW pump and temperature of the room
being reached, then the boiler pump is turned off.
ON / AUTO
Final state: Burn
When Burn state is reached, the process is
controlled so that the heat needed by the system is
generated.
The difference between automatic AUTO and
manual ON mode is the way of determining the
temperature set point. In automatic mode, the week
timer or the external thermostat is used, as in
manual, the user manually sets the desired
temperature, ignoring the week timer or external
thermostat.
OFF
Final state: Idle
When the mode is set to OFF the device will safely
discontinue burning and will reach the Idle state. The
system will not automatically turn itself from OFF to
ON mode.
States
The state sequence is as follows:
0 Idle
1 Clean
2 Ignition
3 Kindle
4 Burn
4.1 Purge
5 Shutdown
6 Clean
7 Wait
An ongoing error monitoring (sensors or state
specific) is performed during operation in all states.
When an error is detected, the burning is
discontinued in the appropriate sequence.
Clean
When cleaning, the cleaner mechanism is
activated for a fixed time. The cleaning is performed
when the device is powered on and off.
Ignition
A preset quantity of fuel is loaded and the lighter
is activated. The device waits until the fuel is ignited
by monitoring the temperature of flue gases or the
flame intensity (depending on configuration). On
successful ignition, it passes to the next state. If the
ignition time runs out before ignition is detected,
then another attempt is made, restarting the ignition
process and loading 50% less fuel. When the
maximum number of attempts is reached, the
controller shuts down, and registers an error.
Kindle
Waiting for the burning process to stabilize. The
flue temperature should raise over a set threshold or
the intensity of the flame should be stable for a time
above a set threshold. Meanwhile fuel is being
periodically fed (if configured). If the ignition time
expires and no stable burning is detected, then a next
ignition attempt will be committed.
Burn
After a stable burning is detected, the controller
goes to burning state. The power (combination of
supplied air and fuel) is determined by the control
algorithm according to temperature(s) set point
and / or external thermostat. By varying the power,
the generated heat is adjusted, satisfying the current
needs of heating in the system.
The burning is interrupted in the following cases:
■
User: pressing power button .
■
Clean time out: if a periodic clean is configured,
then a shutdown is performed followed by clean and
ignition, completing the restart cycle.
■
Week timer: if there is a time set for turning off.
■
No need of heating: when the power has been
at minimum for a set time or the regulated
temperature is exceeded, then the controller shuts
down and transitions to WAIT mode.
■
Loss of flame: flue gases temperature or flame
intensity go below threshold. An error is registered.
Purge
During the burn state, periodically a purge is
committed for a fixed time. The feeder is stopped and
the fan power is increased, thus cleaning the burn
chamber. After the purge time expires, the controller
goes back to Burn.
