Ignition of the furnace and the functional states
The furnace activates by pressing the P2 button longer than 3 seconds. The following functional conditions of the
furnace follow in sequence:
4.5.1
Check Up
At the verification stage, the initial checks of the input signals of the furnace are performed or of the probes and
pressure switches. At this stage, the flue gas motor runs at maximum speed, whereas the auger and the lighter are
deactivated. The check phase takes a few seconds and the successful test is followed by the ignition phase.
4.5.2
Ignition
The ignition phase consists of four interchanging sub-phases, namely the following:
- Preheating phase
- Pellet pre-feeding phase
- Fixed ignition phase
- Variable ignition phase
During the entire duration of the ignition phase, the display shows the message IGNITION. There are no special
markings on the display for sub-phases.
Igni ti on P reheati ng
At this stage, the warming of the lighter takes place before the dosing of pellets starts. In order for the ignition of pellets
to be as efficient as possible, it is recommended that the lighter is already warmed up at the time when the dosing of
pellets starts. At this stage, the lighter is active and the auger is inactive. Flue gas motor runs at lower speeds to boost
heating of the lighter.
Igni ti on P rel oad
At this stage, the initial dosage of pellets occurs i.e. the auger needs a certain amount of pellets for the ignition. At this
stage, the lighter, auger, and flue gas motor are active.
Igni ti on – F ixed Phas e
This phase represents a fixed time period that lasts 180 seconds and in case the requirements for the ignition of the
furnace are reached before the expiration of this phase, it will always last until the end and only after the expiration of the
fixed period, the furnace will move into a stabilisation phase. At this stage, the lighter, auger, and flue gas motor are active.
Igni ti on – V ari able P has e
This phase occurs after a fixed ignition phase. The duration of this phase is a variable period that lasts until the
moment of fulfilment of the conditions for ignition or achieving of the flue gas temperature of 50°C. In the event that the
condition for the ignition of furnace is reached before the expiration of this phase, it is stopped and the next phase - the
stabilisation phase takes place. At this stage, the lighter, auger, and flue gas motor are active.
4.5.3
Stabilisation
The stabilisation phase is a transitional state between the ignition phase and the work phase. This stage begins when
the ignition condition is meet i.e. when the temperature of flue gases reaches 50°C. It lasts three minutes and during that
time the auger, flue gas motor, and lighter are active.
4.5.4
4Normal – Run Mode
After the stabilisation phase, the working mode of the furnace is activated. At this stage there are five power levels that
can be adjusted as explained in the User menu 1. At this stage, the igniter is turned off while the auger, flue gas motor and
the ambient motor are active and work with different intensities depending on the level of power of the furnace. The
furnace works at the set power until it comes to the fulfilment of conditions for modulation.
4.5.5
Modulation
4.5.6
Safety
The condition Safety occurs when flue temperature of flue gas exceeds 275°C. In this phase, the dosing of pellets stops
until the temperature of the flue gas decreases. If there is no temperature reduction in the next 60 seconds, the furnace
goes into an Alarm state and displays a message Er05.
4.5.7
Extinguishing
The furnace shuts down by pressing the P2 button longer than 3 seconds. Then a shutdown phase follows in which the
