7.6.5 Defrost function

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)..
