Chrono Menu
This menu is used for setting the on/off time, i.e. the programmed boiler operation for precisely defined time periods. The
possible modes are daily, weekly and weekend mode. The selected mode appears in the upper left corner of the screen, and
the modes themselves or their times are changed by clicking on the pen below the mode name. During setting, the times are
red and thus inform the user that the change has not been saved.
10.3. 6.1.
Dail y
The day of the week and the programmed time of switching the system on and off are selected. There are three time
ranges for each day. To set the boiler to work during the night, set the times as follows: Set the turn-on time of the boiler for
the previous day of your choice (e.g. 22:00) Set the turn-off time for the previous day at 23:59. Set the turn-on time for the
current day at 00:00. Set the turn-off time for the current day of your choice (e.g. 6:00).
10.3. 6.2.
Weekl y
The set programs are the same for all days of the week. Each day has the option to set three time ranges.
10.3. 6.3.
Weekend
This mode provides the option to select the time ranges Monday ÷ Friday and Saturday ÷ Sunday, and set the on and off
times.

Boiler ignition and function phases
The boiler is turned on by pressing the on/off in the menu in the lower left corner of the screen. After that, the following
functional states of the boiler are listed:
Check Up
The initial test of correctness on boiler input signal, probes and manometers is performed during the check up phase.
During this phase, the flue gases motor is working at maximum speed while the auger and the igniter are turned off. The
check up phase takes a few seconds and the ignition phase will start after a successful test.
Ignition
Ignition Phase is comprised of four consecutive sub-phases:
- Preheating phase
- Pellet preloading phase
- Fixed ignition phase
- Variable ignition phase
During the ignition phase, IGNITION is visible on display. There are no special signs for sub-phases on the display.
Ignition Preheating
During this phase, the igniter is being warmed up before the pellet feed starts. In order to achieve a successful pellet
ignition, the igniter should preferably already be warmed up at the time the pellet feed starts. In this phase, the igniter is
active and the auger inactive. Flue gases motor is working at lower speed to boost the igniter warm up.
Ignition Preload
During this phase, the initial pellet feed starts and the auger supplies a certain amount of pellet for ignition. During this
phase, the igniter, the auger and the flue gases motor are active.
Ignition – Fixed Phase
This phase lasts a fixed time period of 180 seconds and in case the ignition was successful before this phase ended it
will continue until the time expires and the boiler switches to stabilization phase. The igniter, the auger and the flue gases
motor are active during this phase.
Ignition – Variable Phase
This phase follows a fixed ignition phase. The duration of this phase varies from the moment of meeting the conditions
for ignition until the temperature of flue gases is 45°C. In case the ignition of the boiler is achieved before the phase time
