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.

or
+
The display shows the symbol
This device has an automatic evaporator defrost function which
is activated, when the operating conditions require it, during
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.
7.6.6 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)..
