Stand-By
In stand-by mode the machine is ready but no
wash cycle is selected (e.g. when customer
switches the machine on in the morning and
he starts operating in the afternoon); theenergy consumption is reduced and the
temperature in the area under the tank
decreases.

Bo i ler Wait ing Device
The Boiler waiting device allows the rinse cycle to
start only if set boiler temperature btC has been
reached. So:
if the set boiler temperature btC has been reached,
the rinse starts;
if the set boiler temperature btC has been not
reached, the machine continue to wash, increasingthe total cycle time.

Bo i ler Adjus tment
During the rinse cycle the temperature is
measured in the boiler (boiler temperature), while
the digital display must show the rinse
temperature.
Due to the difference between boiler temperature
and rinse temperature, the shown rinse
temperature is calculated by using the boilertemperature and an adjustmentparameter bAJ.
