It allows reducing
energy consumption at
night. In cooling mode,
the system increases
the ambient temperature
within 2 hours, by 2° C
(in heating mode the
system decreases the
temperature by 2° C).
At the end of the 2 hours
the fan of the indoor unit
works at low speed. The
system keeps the room
temperature constant for
the next 5 hours. MARK HEAT PUMP
SPLIT-UNITS are equip-
ped with a device that
automatically regulates
the temperature and
moisture in the room. This function allows the
operating speed of the
outdoor unit’s compres-
sor and indoor unit’s
motor fan to be reduced
to their minimum so as
to reduce noise and
energy consumption to a
minimum. Active only in coo-
ling mode, it allows to
identify compressor
malfunctions following
the refrigerant leak.

Through this function
in heating mode, it is
possible to avoid the
introduction of cold air
into the room following
the defrost cycles. In the case of prolonged
absence, a minimum
temperature level can be
guaranteed inside the
rooms. When the room’s
temperature decreases
than 8°, by the activation
of the anti-freeze func-
tion the system starts
untill this temparature is
reached. This function allows
users to select delay-
ed air conditioner on
and/or off within 24
hours, either via remote
(standard) or via Wi-Fi
(optional). MARK HEAT PUMP
SPLIT-UNIT is equipped
with high-density filters
that ensure the removal
