examples “Back burning”,”Boiler frost”and etc.,can be cleared after pressing and holding button
for one second.

Information about the upcoming action of the timer. If there are no active timers or
the burner is in Standby mode, there is no information under the icon. If there is at
least one activated timer and the burner is ON, under the Icon there will be
information regarding the time or the day of the week of the upcoming action or if
this moment is in the interval of some of the timer, the temperature set by the timer
and how long it will be valid.
Remaining time until the end of processes with limited duration, for example
cleaning, fuelling with the initial fuel dose etc. The stages of power modulation and
maintenance are not with equal duration, because it can be interrupted by activating
a thermostat or changing the temperature, and that's why there is no information
about their ending.
