III.18. Language choice

The user can choose the language version of the controller.
III.19. PID selection
After the PID control function is disabled the controller will operate as a normal
two-state controller and the below listed additional functions will appear in the
main menu:
Feeding time
This option is used to set the fuel feeder operation time. The time should be set
according to the fuel being used and the boiler type.
Feeding pause
Feeding pause time is used to set the pause time in feeder operation. The
pause length should be adapted to the fuel type combusted in the boiler. Wrong
selection of operation and/or pause times may result in boiler malfunctioning
i.e. the fuel may be not fully combusted or the boiler may not reach the preset
temperature. Selection of appropriate times will ensure proper operation of the
boiler.
Temperature alarm
This function is used to set the time after which the temperature alarm is
activated. If the preset boiler temperature is not reached within the set time,
the alarm will go off. The alarm is disabled by pressing the pulser knob. Once
the alarm is disabled the controller will return to the most recent operation
mode.
Blowing rate
The function controls the operating speed of the fan. The adjustment range is
between 1 and 100% (equivalent to fan speeds). The higher the speed is, the
faster the fan operates, where 1% stands for the minimum fan speed and
100% is the maximum speed.
Sustained operation
This function is used to set the fuel feeding time when in sustain mode
(operation above the preset temperature). This prevents the boiler from
damping if the actual temperature is higher than the preset one.
ATTENTION: Wrong setting may cause constant temperature increase.
Sustain pause
This function is used to set the pause time in fuel feeder operation when in the
sustain mode.
ATTENTION: Wrong setting may cause constant temperature increase! The
sustain pause should not be too short.
Fan in sustain mode
The function allows the user to select working and pause times during fan
