in % for minimum boiler power. Therefore, the boiler control unit is able to
maintain the required oxygen in the boiler within 1 - 1% of the set value. We are also
talking about the average value of oxygen maintained in the boiler throughout its
operation.
Short-term deviations of oxygen from the set value are perfectly normal due to external
factors such as changes in chimney draft, cleaning the burner by increasing the fan speed
(Burner Cleaning function in the Main Settings), etc.
According

size.
* Connecting the Lambda probe to one of the RS data outputs in the control unit.
6. De-ashing *
Activating the motor that drives the worm that empties the ash from the boiler into an
external container. Extends the requirement for manual cleaning of the boiler.
6.1 Operating time
The operating time of the motor that drives the ash removal worm. We recommend to
set it between 5-20min, depending on the amount of ash generated. The larger the
burner, the longer the cleaning time.
5-20min
6.2 Pause time
For how long the motor is in a stand-by before reactivation occurs. This depends on the
pellet quality and burner size. The recommended setting is anything between 2-20
hours.
2-20h
* Connecting the Ash Remover to the "De-ashing" output on the control unit.
7. Compressor cleaning 1,
2, 3 *
2
Cleaning the burner and boiler exchanger with the compressor set.
On state
Off state
7.1 ON
In the on state, the compressor always cleans after the extinction phase
and also during PID operation according to the time set in the Pause Time
function. After cleaning during PID mode, the light is lost (the photosensor
does not detect the flame) and the boiler goes into Ignition after the set
time. This time is the 20s without flame set in the Service menu, in the
Operation Check function.
On
7.2 OFF
When disabled, the compressor only cleans after extinction and does not
clean during PID mode.
Off
7.3 Cleaning time
The compressor's total cleaning time. Recommended between 1-3 min.
Bigger burner, longer cleaning time. During this time, the solenoid valve
opens and closes periodically according to the values set in the Open Time
and Cycle Time functions.
When set to On, it is necessary to complete the total Cleaning Time before
the automatic ignition occurs so that the compressor does not blow the
pellet dose for automatic ignition. Therefore, set the Cleaning Time to a
maximum of 1min.
1min
3min
7.4 Opening time
Opening of the solenoid valve. Time of one cleaning period.
We recommend between 1-2s.
2s
2s
7.5 Cycle time
The time required to re-pressurise the compressor so that the valve can be
reopened and cleaned again. We recommend 20s.
25s
20s
7.6 Pause time
The time of pause between cleaning. Recommended between 10-20 hours.
This time is only valid when cleaning during PID operation, i.e., when the
compressor is ON.
10-24h
Not taken
into
account*
1
* Compressor in the Off setting works only after the Extinction phase (in Off state). Therefore, we do not consider the Pause Time.
* Connecting the compressor solenoid valve to one of the "Compressor 1, 2 or 2" outputs in the control unit.
8. Built-in valve 1, 2 *
1
Controls the mixing valve for one heating circuit.
8.1 Switch off the valve
Deactivate the mixing valve if you do not want to use it at that moment.
8.2 Switch on the valve
Activating the mixing valve.
8.3 Set valve temperature
*
2
Enter the desired temperature to be maintained by the mixing valve. The maximum
adjustable temperature on the mixing valve is determined by the Mixing Valve Type
function.
