How To Turn The Water Heater On And Off And Unlock The Keys; Setting The Clock; Setting The Time Bands; Setting The Hot Water Set-Point - Ferroli EGEA 90 LT Handbuch Für Betrieb Und Installation

The user interface of this water heater model consists of four
capacitive buttons, and a LED display.
As soon as the water heater is powered the four buttons are
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
display show the water temperature in °C, measured with the
upper water probe if parameter P11 is set to 1 or with the lower
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
or not of alarms, Wi-Fi connection status, and other information
on product status.
2.5 HOW TO TURN THE WATER HEATER ON AND
OFF AND UNLOCK THE KEYS
When the water heater is correctly powered it can be "ON"
and, therefore, in one of the available operating modes (ECO,
Automatic, 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 connec-
tion 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.
