Off mode
In the event of long periods of absence
from the home, we recommend you
set your thermostat to the off mode;
this way, the heating/cooling and DHW
system will not operate, but the an-
ti-freeze protection on the unit will be
guaranteed throughout the winter.
Warning: the electricity supply must
stay connected and water must cir-
culate inside the unit (check for in-
stance whether the shut-off valves
are open). In especially harsh cli-
mates, we recommend the use of
solutions with glycol anti-freeze
