previously specified mode and is controlled according to the specified
program.
EXCEPTION:
If the boiler was at operating status “Heating up”, “Pre-heating” or
“Ignition” troubleshooting is started automatically. When error
correction has been carried out (approx. 20 min) the warning, “Clean/
check burner”, is shown on the display. The warning can only be
acknowledged after checking the burner.

safety temperature limiter (1) must be manually unlocked:
Unscrew the cap on the safety temperature limiter
Reset the safety temperature limiter by pressing with a screw-driver.
