How to turn the burner on/off:
Press the On/Off button to enter the switch mode menu:
Press the up or down navigation buttons (
▲
or
▼
) to select a row and confirm your choice by
pressing the On/Off button. To abort your choice and return to the main screen press the left navigation
button (
◄
) or press no buttons for more than 5 seconds. The field “Fuel type” on the main screen
shows the currently selected fuel that the burner is set to burn. If this field is missing, the burner is
either off or is about to turn off. The most certain indication that the burner is off is that there is no
green text on the bottom line with any of the work phases from table 1.

Extinguishing
While in Standby mode, the burner doesn't work. If it was working right before switching to this mode,
it will instantly start the extinguishing procedure. It needs some time to completely put down the fire
and to perform the Cleaning on Stop procedure. The burner's and the boiler's aggregates might still
work for some time during the Standby mode.
The installations' circulation pumps keep working until the conditions for them to work are fulfilled,
even if the burner is off, thus ensuring the maximum usage of the heat energy.
The Fuel type field appears on the screen right after the burner is on. Then the Cleaning on Start
procedure and the ignition start if all of the necessary conditions are fulfilled: the temperature of the
boiler is lower than the set temperature, the room thermostat and the WH input for external stop switch
are not activated, there are no error messages or activated timers that require the burner to stay off. All
