backlit and all the icons and display segments light up simulta-
neously for 3 s.
During normal operation of the product the three digits on the

water probe if P11 = 0.
During modification of the selected operating mode set-point,
the set-point temperature is shown on the display.
The icons indicate the selected operating mode, the presence

on product status.
6.1 Turning the water heater on and off and unlocking the
buttons
When the water heater is correctly powered it can be "ON" and,
therefore, in one of the available operating modes (ECO, Auto-
matic, etc.) or in standby mode.
During standby mode the four capacitive buttons are backlit for
easy visibility, the Wi-Fi icon is lit up according to the connection
status with an external Wi-Fi router (not supplied) and, in the
absence of alarms or frost protection active, all other icons as
well as the segments of the three digits are off.
Turning on
With the water heater in standby mode and "button lock" func-
+
tion active (padlock icon at the bottom left lit up), it is necessary
to first "unlock" the buttons by pressing the ON/OFF button for
+
at least 3 seconds (the padlock icon goes off), then press the
ON/OFF button again for 3 seconds to turn on the water heater.
Turning off
With the water heater on and "button lock" function active, it
is necessary to first "unlock" the buttons by pressing the ON/
OFF button for at least 3 seconds, then press the ON/OFF but-
ton again for 3 seconds to turn off the water heater (putting in
standby mode).
In any status, 60 seconds after the last press of any of the four
user interface buttons, the button lock function is automatically
activated to prevent possible interactions with the water heater,
e.g. by children, etc. At the same time the backlighting level of
the buttons and display decreases to reduce the unit's energy
consumption.
By pressing any of the four buttons, the backlighting of the but-
tons and display will immediately return to its normal level for
better visibility.
