are open

The appliance is powered and is normally off.
The display shows in sequence (from off to on) every 2 seconds a
segment of 2 digits to compose the writing "oF" (off). When "oF" is

mestic hot water.

stand-by.

every 2 seconds a segment to compose the writing "Sb".
When "Sb" is visible on the display, it remains on for 10 seconds, then
it blinks 5 times and switches off for 5 seconds. Then the activation
sequence of the segments restarts.
In stand-by, if the temperature measured by the domestic hot water
probe is > 65°C the fan is started. When the temperature drops below
65°C the fan remains powered for another minute and then is switched
off.

rameter “Domestic Hot Water Waiting Time” has passed (about
