R elay 2 closed (if no alarms,
the relay is normally open).
In s afe mode. Mixing valve c loses, i.e. only cold water enters.
Adjustment or disinfec tion or thermal s hoc k is cancelled.
All alarm indications are c leared when the c ause of the alarm has been removed.
R elay 2 open.
The alarm relay does not
change s tatus.
All functions are ensured.
The return probe, if present, is used as a monitor only, since it does not generate an alarm if faulty.
R elay 2 closed.
(if no alarms, the relay is
normally open).
No disinfection, but adjustment c ontinues and thermal shoc k is pos s ible.
When the first button is pressed, the relay re-opens; indication remains on the display.
In all c as es, all alarm indications are c leared when the c aus e of the alarm has been removed.
R elay 2 open.
The alarm relay does not
change s tatus.
Disinfection failure does not generate any alarms.
R elay 2 closed.
(if no alarms, the relay is
normally open).
When the first button is pressed, the relay re-opens; indication remains on the display.
In all c as es, all alarm indications are c leared when the c aus e of the alarm has been removed, in this c ase when the next disinfec tion
is s uc c ess fully completed.
Note: if program 0 is s et, any unresolved alarm indication due to incomplete disinfec tion is cleared.
R elay 2 closed.
(if no alarms, the relay is

Alarms generated. The thermal s hock function is potentially dangerous for us ers of the s ys tem.
When the first button is pressed, the relay re-opens; indication remains on the display.
In all c as es, all alarm indications are c leared when the c aus e of the alarm has been removed, in in this c as e when the shock function
has ended and the applianc e begins adjustment again.
R elay 2 closed.
(if no alarms, the relay is
normally open).
If there is a mains power failure, the back-up battery keeps the applianc e’s internal c lock running.
In this situation, all ac tuations are inhibited (the relays cannot be operated), and therefore all the adjustment, disinfec tion and thermal
shoc k programs. In this status, the appliance goes into Low Power mode in order to ensure maximum autonomy.
The R S 485 interfac e is not available.
When power is res
tored, the blac kout alarm (AL5) is s tored in the log, and the appliance resumes operation as defined in the
programs; there are no alarm indications.
However, if the mains power failure las ts long enough for the battery to become discharged, there is a general reset when power is
res tored.
The printed circuit board has a button for hardware reset of the applianc e. This button cannot be operated from the front panel, but
only by opening the door of the appliance and acc es sing the printed c ircuit board.
If the appliance is reset accidentally, or intentionally by pres s ing the special hidden button, or by interference (lightning, etc.), the
correc t time and date s ettings are lost.
Settings
made by the us er are also lost, and the factory values are reloaded for all parameters and s ettings .
Therefore, until the c orrect date and time are re-entered:
Appliance remains active in adjustment mode.
Disinfection is inhibited.
Thermal s hock program is inhibited (but thermal s hock c an still be forced manually or remotely).
When the c urrent date and time have been s et (manually or remotely), the dev
ice c omes out of the alarm condition and res umes
normal operation. All alarm indic ations are c leared.
R elay 2 open.
The alarm relay does not
change s tatus.
While in operation, the level of c harge in the battery is chec ked periodically (about every 24 h), and the rec harge function is
activated if neces s ary. If the parameter readings are not within the s pec ified range, it means the battery is damaged and must be
replaced.
However, the applianc e c ontinues performing the spec ified programs, s ince a battery fault does not affec t any of the appliance
functions
(unles s there is a blac kout).
NOTE : for the battery replac ement operation refer to the proc edure des c ribed on page 20.
Operability after alarm (page 2)
No relay action.
