ted by persons (with normal pollution). Avoid using for any other purpose. This 
appliance should not be used in places with suspended dust/powder or in po-
tentially explosive atmospheres, in very damp environments or in the presence 
of oil in suspension or in particularly aggressive atmospheres.

The units have the following operating limits:
- it can’t be installed in areas with anomalous heat and humidity condi

-

tions;

- it can’t be installed outdoors;
- it can’t be installed in explosive environments;
- it can’t be installed in a corrosive atmosphere.

USING THE CONTROL PANEL

If  the  appliance  has  a  built-in  control  panel,  raise  the  flap  and  proceed  as         
follows.

Cooling mode

Put the season selector switch from the off position ( ) to the summer position 
( ).
The fan starts immediately.

Heating mode

Put the season selector switch from the off position ( )  to  the  winter  position        
( ). 
The fan starts.
In models with minimum temperature thermostat (optional), the fan starts when 
the internal heat exchanger is sufficiently hot. If the water is not hot enough, the 
fan does not start.

Selecting the fan speed

Put the selector switch to the required speed.
The higher the speed the quicker the room will be heated/cooled, although ap-
pliance operation will be noisier (Pic. 22).

The room temperature may be set approx. between 10°C and 30°C. If the 

appliance does not have a built-in control panel, but is controlled by a 
wall-mounted thermostat, refer to the thermostat instructions for use.

Automatic temperature adjustment

This control panel has a built-in temperature sensor, which measures the room 
air temperature. This information is used for the automatic control of the fan 
or introduction of water into the internal exchanger through the solenoid valve   
(optional).
The appliance this keeps the room at the temperature set by the user.
