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 on
SLI and RSI
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

In order to control the device from the control panel, it first
has to be connected to mains. If the power line is provided
with a main switch, it should be on.
- Start the system by toggling the main switch
If one of the 2 symbols flashes it means that the water
temperature (hot or cold) is not met and it makes the fan
stop until the water reaches the requested temperature.
If after powering the device the board detects the H2
probe, the start-up will take place under normal conditions
with minimum and maximum thresholds.
The board can also operate without a H2 probe, case in
which the fan stop thresholds will be ignored.
When the control is in this operating mode, the anti-freeze
safety is secured. If the room temperature drops below
5°C the hot water solenoid valve and boiler go-ahead
outputs activate.
The adjustment range goes from 16 to 28 °C, with a
resolution of 0.5 °C, but the system also allows the out of
range values 5 °C, ma sono consentiti anche i valori fuori
scala di 5 °C and 40 °C (except when in auto mode).
These values should be set only for short periods of time, the
selection should then be adjusted to an intermediate value.
The control is very precise, set it to the desired value and
wait for it to run the adjustment based on the actually
detected room temperature.
To activate the device
Key Operation Display
Press the Heating / Cooling key for about 2 seconds to switch between heating and
cooling operating modes; the selection is shown by 2 heating on or cooling on symbols
that will light up.
In heating, the symbol is alight when the setpoint is higher than the room temperature,
both are switched off when the setpoint is lower.
In cooling, the symbol is alight when the setpoint is lower than the room temperature,
both are switched off when the setpoint is higher.
In 4-pipe versions provided with automatic cooling/heating regulation system if the
2 symbols are switched on at the same time it means that the setpoint has been
reached (neutral band).

actual distance between the room temperature and the
setpoint using a PI algorithm.
The ventilation speed is limited at a more reduced
maximum value.
By selecting this operating mode the ventilation speed is
significantly reduced and the set temperature is changed
automatically as follows:
- decreased by 1° C after one hour and by another
degree after 2 hours in heating function;
- increased by 1°C after one hour and by another degree
after 2 hours in cooling function.
In this operating mode, you will immediately obtain
maximum power output both in heating and in cooling.
After reaching the desired room temperature you should
select one of the other 3 operating modes to increase the
thermal and acoustic comfort.

External cleaning
Disconnect the unit from the power supply before
each cleaning and maintenance intervention by setting
the main power supply switch to off.
Wait for the components to cool down in order to
avoid any burns.
Do not use abrasive sponges or abrasive or corrosive
detergents as you might damage the painted surfaces.
Clean the external surfaces of the cooler-radiator using a
soft cloth dampened with water.
Cleaning the air suction filter
After a period of continuous operation, depending also on
the concentration of impurities in the air, or whenever you
have to restart the system after a period of inactivity, you
should proceed as described below.
- remove the front grill by lifting it slightly and turning it
until releasing it from its housing;
- remove the filter by pulling it horizontally and outwards.

Suggestions for power saving
- Keep the filters clean;
- keep the doors and windows of the locations fitted with
air conditioning systems closed as much as possible;
- during summer limit as much as possible the entry of
direct sun rays in the rooms fitted with air conditioning
systems (use curtains, blinds, etc.).
- For mobile panel versions lean it in its position parallel
to the front and press until locking it.
- For the grill with flaps versions insert the two tabs in
the appropriate slots, turn them and hook them giving
them a slight hit on the top.
