METHOD
The burner can work either in continuous automatic mode (
Auto
)
or in mode with timers. When it is
in a timer mode, the burner works only during the intervals of the day set by the user. While working,
the burner goes through several stages: cleaning, igniting, burning, extinguishing, cleaning again and
initial state.
Every ignition begins with a cleaning cycle, which is indicated by the symbol for a fan in the upper
right corner of the screen (field
work phase
). The purpose is to clean all leftovers of the previous
burning. At first, for a certain time, set in the
Cleaning on Start
menu, only the primary fan works and
after that the additional cleaning fan turns on, if there is any and if it is activated from the Hardware
Setup menu. After that the burner goes to igniting phase.
The igniting is indicated by the symbol
in the upper right corner of the screen (field
work phase
).
A portion of pellets, which is going to be ignited by the electrical heater and the fan, is loaded. When
the flame sensor indicates the pellets are burning, a symbol appears in the
flame indicator
field and
the burner goes to burning phase. If the pellets do not ignite before the set time is up, a new portion of
pellets is loaded and a new attempt for ignition is made. After as many retries as set in the menu
General Setup
, if there still is no fire, the burner stops and a message
Ignition fail
appears.
The logic on igniting is as follows:
1. At first the heater turns on and works without air fan for as long as it is set in the menu
Cycle
Setup
, line
Heater
. The purpose is to heat up faster.
Should watch out for the heater not to get
overheated and damaged, if the time for turning on the cooling is too long!
2. At the same time, while turning on the heater, a dose of pellets is fed for so long as it is set in
the menu:
General Setup
, line
Feed
.
3. After the time for the heater, working without air fan, runs out, there are two more steps on
which the air fan turns on. The idea is that the air fan works less intensive at first, so that it
doesn't extinguish the fire, but only keeps the needed oxygen level. After the fire is steady, the
fan's speed can be increased for full igniting of all the pellets.
4. If the photo sensor detects enough light, which can be set from the menu
IR Level Setup,
line
, the ignition cycle breaks off and the burner goes to work mode. Two parameters are used for
recognizing the light level – light level, measured by the photo sensor and time the illumination
is over this level.
