This control makes the room temperature adjustment
completely autonomous (with adjustable offset via
keyboard) through AUTO, SILENT, NIGHT and MAX
pictograms by means of a probe located in the lower
side of the device ensuring anti-freeze safety even
when set to stand-by .
The control panel has its own memory, therefore no
settings will be lost in case of shut-down or power
outage .
The controls cannot be installed VN / VO / VI
versions .
After 20 seconds from the last action the panel
brightness will be reduced to increase the comfort
during night use and on the display will appear
the room temperature . Press any key to restore
maximum brightness .
The 10 kΩ water temperature probe located in the
device battery can manage the minimum in heating
(30 °C) and maximum in cooling (20 °C) functions .
You can set the various functions through the 8 backlit keys:
The display also offers information on the statuses and on any active alarms through 8 specific symbols:
Automatic operation
Silent operation
Maximum ventilation speed
Night function
Heating on

temperature
Heating / Cooling: allows switching
between heating and cooling
The ventilation speed will be adjusted
automatically between a minimum and a
maximum value .
Night function: the ventilation speed is
significantly reduced and the set
temperature is changed automatically
Operation at maximum speed: allows
setting he maximum ventilation speed

If after powering the equipment the board
detects the probe, the start-up will take
place under normal conditions with minimum
water temperature in heating (30 °C) and
maximum water temperature in cooling (20
°C) functions .
The board can also operate without probe,
case in which the minimum and maximum
thresholds will be ignored .
