The "Output selection" menu is available only for the PID option enabled (see PID). This parameter helps to set
the burner operation parameters for each output (minimum, average and maximum). It is possible to choose a
particular burner output by selecting one of the following options:
• Minimum output
• Average output
• Maximum output
The burner operates at the selected output until the boiler heats up to the set temperature. At this time, it is
recommended to control the burning parameters described above (see Minimum output). After making the
adjustments, set the AUTO option or disable the PID operation (see PID).
Feeding
Burning feeding consists in burner operation at minimum fuel consumption. Its aim is to feed heat and quickly
enter the burning phase without following the burner turn-on and turn-off procedures. It allows reducing
electric energy consumption of the burner (no heater) and quickly raising the temperature in the boiler. Using
this function is recommended in the WINTER mode. The following is a discussion of the available parameters.
These parameters define burner operation in a comparable manner to operation in a normal burning phase.
However, the parameter settings in FEEDING should generate a minimum burner output and not lead to burner
turn off.
Feeding portions should be much smaller than the minimum output settings. Parameter settings must be made
after heating the boiler and an additional reduction of preset boiler temperature for the control time. This way,
the burner adjustment time can be prolonged.
Attention should be paid to stable operation of the fan. It may happen that when the output is low, the fan
stops which can lead to its damage. On the other hand, high airflow will burn the fuel too fast.
After reaching the desired temperature, the regulator always goes to the burning feed phase. It is not important
whether the burner has the PID parameter turned on or not (the turn-off point varies depending on the PID
setting - see Burning). However, immediate stopping can be triggered on the burner by setting the parameter
value to 0. If a different value is set, the regulator feeds the burning process by waiting for the temperature to
drop to continue the process. If the temperature does not drop for the set time, the stopping function will be
turned on (description below).
Stopping
The stopping process can be activated manually (SYMBOLS menu) or triggered automatically. In the first
stopping phase, the dispenser feeder is blocked. The burner fuel is burned the same way as in the burning phase
until the flame brightness decreases below a set value (see Flame Brightness). From this moment, the regulator
launches the final stopping the time of which is set using the "fuel burning time" parameter. At this time, the
