Meaning
Purge the product, heating circuit and cylinder charging circuit. The product does not start up. The
heating pump runs intermittently. After approx. 6.5 minutes, the product switches to the cylinder char-
ging pump (alternatively, by pressing the i button).
Start up the burner at maximum load. The product works at maximum load after a successful ignition.
Start up the burner at minimum load. The product works at minimum load after a successful ignition.
Test function for the safety cut-out (SCO): The burner is switched on at maximum power and the
pumps are switched off; the temperature control is switched off so that the burner heats up until the
safety cut-out is triggered by reaching the safety cut-out temperature.
