Ignition of the Boiler and Functional Conditions
The boiler is switched on by pressing the P2 key for more than 3 seconds. The following functional conditions of the furnace are
then seen:
Check Up
In the Check Up Phase, you may examine boiler input signals and whether the probes and pressure switches function
properly. At this stage, the flue gas motor runs at the maximum speed and the auger and lighter are switched off. The Check Up
Phase takes a few seconds and after it has been completed successfully, the Ignition Phase follows.
Ignition
The ignition Phase consists of four sub-phases which follow one another and they are the following:
- Preheating Phase
- Pellet Preload Phase
- Fixed Phase
- Variable Phase
For the entire duration of the Ignition Phase, the message IGNITION is displayed. There are no special tags on the sub-phase
display.
Ignition Preheating
At this stage, the lighter is heated before the pellet is starting to be loaded. In order to make pellet ignition as efficient as
possible, it is desirable that the lighter is already heated at the moment when the pellet loading starts. At this stage, the lighter
is active and the auger is inactive. The flue gas motor runs at a lower speed to accelerate the heating of the lighter.
Ignition Preload
At this stage, pellets are preloaded, i.e. the auger loads a certain quantity of pellets that is necessary for ignition. At this stage,
the lighter, auger and flue gas motor are active.
Ignition – Fixed Phase
This phase represents a fixed period of 180 seconds and in case the furnace ignition requirement is reached before the end
of this phase, it will always last until the end, and the furnace goes into the Stabilization Phase only after the expiration of this
fixed period of time. At this stage, the lighter, auger and flue gas motor are active.
Ignition – Variable Phase
This phase takes place after the Fixed Phase. The duration of this phase varies and it lasts up to the moment when the
conditions for ignition are fulfilled, or until the flue gas temperature reaches 45 ° C. In the event that the conditions for the ignition
of the boiler have been fulfilled before the end of this phase, it is interrupted and the next phase - the Stabilization Phase, takes
place. At this stage, the lighter, auger and flue gas motor are active.
Stabilization
The Stabilization Phase is a transition state between the Ignition Phase and Run Mode. This phase occurs when the
conditions for the ignition have been fulfilled, or when the flue gas temperature reaches 45 ° C. It lasts for three minutes and
during this time the auger, flue gas motor and lighter are active.
Run Mode
After the Stabilization Phase, the furnace Run Mode Phase takes place. At this stage, there are five power levels that can be
adjusted (see 10.3.1.1). At this stage, the lighter is switched off while the auger, flue gas motor and pump are active and operate
at different intensities depending on the power level of the furnace. The boiler operates at a given power until the conditions for
Modulation have been met.
