5.1.3 - Anti-legionella alarm
The anti-legionella alarm is the only alarm “with
acknowledgement”. If the system is not able to complete the
anti-legionella cycle, the anti-legionella alarm is displayed.

is aware of the fact that the system is not able to complete
this cycle.
Proceed as follows to acknowledge the alarm:
1.- Press the “Bell” key on the main menu;
2.- Select the Alarms list menu and press the knob;
3.- The alarm (or alarms) present at that time are displayed;
4.- Select Acknowledge by pressing the knob;
5.- Press the knob to confirm;
6.- Select Execute and press the knob;
7.- Press the
ESC
key to return to the main menu.
NOTE! Acknowledgement of the error relating to the
fact that the anti-legionella cycle has not been executed
satisfactorily remains in the device register.
ATTENTION!!! Failure to complete the anti-legionella cycle
can seriously harm the health of people and animals.

For the purpose of diagnostics or to solve an emergency
situation, you can use the
Diagnostics
menu at any time to

sensor, an analogue or digital output (outputs controlling heat
generators or pumps) or a digital input (RT or DHW enabe/

and set the value to be forced for
this item;

to draw attention to the fact that the system is in forced
operation.

A017 Inputs/outputs forcing”
alarm
is not able to activate the “Alarm” output (contacts C;

5.3 - Saving and/or restoring
the configuration
Once the system configuration has been set, together with all
the various operating parameters, this setting can be saved
and recalled at any time by setting the “ Configuration->Dt
Control->Save/restore->Sett.service save = Executed
parameter.
An image of all the settings has now been saved in the TutorBit
memory.
If you want to reload the same image, simply use the
Configuration->Dt Control->Save/restore->Sett.service
load = Executed command.
If you want to clear the TutorBit and start from the default
settings, simply access the Configuration->Dt Control-
>Save/restore->Set Default = Executed command.
