Pressing On / Off button in the middle of the screen displays a menu for mode select:
Selected row
Changing of the mode can be made with virtual buttons "▲" or "▼"and then pressing the button
"Enter" to confirm the changing or directly with touching the selection row from the menu without
additional confirmation. You can choose between three operation modes: On, Off and Timers.
When pressing the exit button to the main screen the mode doesn't change. If no button is being
pressed for more than 5 seconds, the screen will exit without changing the mode or status. To be
sure that the burner is turned off after choosing Off mode, you must be sure that on the bottom of
the display there is no message in green with any of the working stages of the burner. The working
stages are described as follows below in Table 1:
Table1
1 Cleaning
2 Feeding
3 Ignition
4 Unfolding fire
5 Suspend
When the burner is in "Off" mode, it will not work unless the frost protection mode is activated. If
the burner goes to "Off", and it was ignited, it will switch to the extinguishing procedure.
Completing the fire extinguishing and cleaning process will require some time. It is normal for the
burner and boiler units to continue to operate even after switching to "Off" mode.
The circulation pumps can operate even when the burner is extinguished, but there are certain
conditions for their operation. This way the heating energy of the water in the boiler will be used
while it is available in the tank.
