User, Installations and Maintenance Manual

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.

8.1  

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

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.

8.2  Setting the clock

the desired operating mode for the time band (ECO, AUTOMAT-

IC, BOOST, ELECTRIC, VENTILATION).

Press 

 to confirm and exit.

Note
