When the control is set to this mode of operation, it ensures safety against freezing. In the event that am-
bient temperature drops below 5°C, the hot water solenoid valve and the fan motor at minimum speed are
activated, the display shows code "AF".
7.6 - AUTOMATIC COOLING /HEATING MODE
Setting this type of adjustment allows the control to automatically carry out the selection of cooling or heating
mode, based on the difference between temperature set by the user and ambient temperature.
a. To activate/deactivate this function, keep the cooling/heating selection key "B1" pressed for 10 seconds
until the blue and red symbols (A5) light up alternatively.
This setting is maintained also in the event of power interruption.
b. Then, ensure that when the set temperature is changed, the unit alternates cooling only (blue indicator
"A5" on), fan (blue and red indicators off) or heating only (red v "A5" on) mode.
In this mode, read ambient temperature compensation is disabled.
This setting can only be carried out from the panel on board the machine.
If automatic mode is active, it is not possible to change the operating mode from the remote
controller.
7.7 - MANUAL COOLING/ HEATING MODE
From board the machine
a. To activate/deactivate this function, keep cooling/heating selection key "T3" pressed for 10 seconds until
the blue and red symbols (A5) light up alternatively.
This setting is maintained also in the event of power interruption.
b. Pressing key "T3" for 2 seconds allows to cyclically select cooling (blue LED), heating (red LED) or fan
(red LED and blue LED off) mode.
From remote controller
a. To select this function, press the key "B2" until the heating only (D10) or cooling only (D11) symbol appears
on the remote controller.
From the remote controller it is not possible to change setting from manual mode to automatic mode.
7.8 - FAN MODE
When this mode is used, the appliance does not exercise any action on temperature or air humidity in the
room, but only keeps it in circulation.
From board the machine
a. Pressing key "T3" for 2 seconds allows to cyclically select cooling (blue LED), heating (red LED) or fan
(red LED and blue LED off) mode.
b. Under this operating mode, the internal fan is always on and it is possible to select the desired speed of
the fan at any moment by pressing the specific key "T2".
The desired temperature which operates on the automatic speed of the fan can be selected only
from board the machine: the more the desired temperature deviates from ambient temperature,
the more the fan speed is high.
These are the possible speeds for the fan.
MAXIMUM speed
MINIMUM speed
