Ignition – Fixed Stage
This stage is a fixed time period of 180 seconds and in case the conditions for stove ignition are reached before the end of this
stage, it will always last until the stove is switched to the stabilization stage only after the expiration of a fixed period of time. At
this stage, the igniter, auger and flue gas fan are active.
Ignition – Variable Stage
This stage occurs after a fixed ignition stage. The duration of this stage is a variable time period that lasts up to the moment
when the ignition conditions are met, or until the flue gas temperature has reached at 45°C. When the conditions for igniting the
boiler is met before the end of this stage, it is interrupted and the next stage - the stabilization stage starts. At this stage, the igniter,
auger and flue gas fan are active.
Stabilization
The stabilization stage is a transient state between the ignition stage and the stage of operation. This stage occurs when the
ignition condition is met, i.e. when the flue gas temperature reaches 45°C. It lasts for three minutes and during this time the auger,
flue gas fan and igniter are active.
Run Mode
After the stabilization stage, the stove operation stage starts. At this stage, there are five power levels that can be adjusted. At
this stage, the igniter is switched off while the auger, flue gas fan and pump are active and operate at different intensities depending
on the power level of the stove. The stove works at a given power until the modulation conditions are met.
Modulation
The stove goes into the state of modulation when one of the three conditions is fulfilled:
1.
When the stove reaches the set water temperature
2.
When the stove reaches the set ambient temperature
3.
When the flue gas temperature reaches a value greater than 200°C
In the state of modulation, the stove works at minimum power - power 1, until the temperature decreases below the limit value.
Standby
The stove goes into Standby when one of the two conditions is met:
1. When the boiler reaches the set water temperature, it goes into modulation and continues to increase the water temperature
by inertia up to the value 4°C higher than the set water temperature in the boiler.
2. When an external (room) thermostat is responding
In Standby mode, the pellets insertion stops and the stove is switched off. The stove is switched on again when the water
temperature in the boiler is reduced by 4°C below the set value or when the room thermostat is deactivated.
Safety
Safety state occurs when the flue gas temperature exceeds 230°C and when the water temperature in the boiler reaches 85°C.
At this stage, pellets insertion stops until the flue gas temperature is below 230°C or the water temperature in the boiler is below
85°C. If the temperature is not reduced in the next 60 seconds, the boiler goes into the Alarm state and sends the Er04 or Er05
message.
Extingushing
The stove is switched off by pressing the P2 button for more than 3 seconds. Then an extinguishing stage occurs in which the
insertion of pellets is stopped and the flue gas fan and pump work at the maximum capacity in order to cool the boiler down as
soon as possible. The minimum duration of the extinguishing stage is 300 seconds, and the condition for switching off the stove
completely is when the flue gas temperature is less than 70°C.
OFF
In this state, the stove is switched off, i.e. no outlet on the stove (flue gas fan, pump, igniter and auger) is not active.
Block
The Block state occurs in the event of an error or an alarm. In the Block state, the exhaust fan, the auger and the igniter are off.
Hold down the P2 button for 3 seconds to exit: if there are no more block conditions or there is no cause of alarm, the system will
turn off.
Recover Ignition
The stove goes into this stage in two cases:
1.
If the power supply is interrupted during the operation and the flue gas temperature is greater than 45°C.
2.
Pressing the main switch at the moment the stove is in the extinguishing stage.
