6.6 Additional functions
6.6.1 Anti-Legionella
The display shows the symbol .
Every two weeks, at the set time, a water heating cycle is car-
ried out by means of the heating element inside the tank, up to
the anti-legionella temperature, maintaining it for the set time.
If, on reaching the anti-legionella temperature, the cycle is not
performed correctly within 10 hours, it is stopped and will be run
again after 2 weeks.
If the request for the anti-legionella function occurs with HOLI-
DAY mode selected, the anti-legionella cycle will be carried out
immediately when the unit is reactivated after the set days of
absence.

6.6.2 Defrost function
The display shows the symbol .
This equipment has an automatic evaporator defrost function
which is activated, when the operating conditions require it, dur-
ing heat pump operation.
Defrosting occurs through the injection of hot gas into the evap-
orator, allowing it to be rapidly defrosted.
During defrosting, the heating element, which the equipment is
provided with, is switched off unless otherwise set via the in-
staller menu (parameter P6).
The max. duration of defrosting is 8 minutes.
6.6.2.1 Frost protection
The display shows the symbol .
This protection prevents the water temperature inside the tank
from reaching values close to zero.
With the equipment in standby mode, when the water tempera-
ture inside the tank is below or equal to 5°C (parameter configu-
rable via installer menu), the frost protection function activates,
which switches on the heating element until 12°C is reached
(parameter configurable via installer menu).
