OPERATING DETAIL
CASSETTE WITH A CONTROL BOARD THAT IS MANAGED ONBOARD
The following commands be given by the buttons on the eall-mounted control.
Switching on/off
Press the POWER button to switch the cassette on or off. When the system has
been switched on, it will operate according to the settings shown on the display.
The
POWER indicator light on the display comes on.
Fan
Press the FAN button to select the fan speed (high, medium, low or auto mode).
The display instantly shows the operating status.
Auto mode
When the fan speed is set in the AUTO mode, the speed is adjusted automa-
tically according to the difference between the room temperature and the set
temperature:
- If the difference is 3°C or more, the speed is
HIGH ;
- If the difference is 2°C, the speed is MEDIUM ;
- If the difference is 1°C or less, the speed is LOW .
Function mode:
- Ventilation ( FAN )
- Air-conditioning ( COOL )
- Dehumidifying ( DRY )
- Heating ( HEAT )
- Automatic ( AUTO )
FAN
The writing FAN appears on the air-conditioner control display. In this mode the
unit operates as a fan only. The
SLEEP
and buttons are not used.
COOL
The writing COOL appears on the air-conditioner control display. The unit ope-
rates in the air-conditioning mode.
- the zone valve starts if Troom
≥ Tset+1
- the zone valve stops if Troom ≤ Tset
In any case activation of the zone valve is subject to 3 minutes delay each time
it stops.
DRY
The writing DRY appears on the air-conditioner control display. The unit ope-
rates in the dehumidifying mode to reduce the percentage of humidity in the
room.
HEAT
The writing HEAT appears on the air-conditioner control display. The unit ope-
rates in the air-conditioning mode.
- the zone valve starts if Troom
≤ Tset -1
- the zone valve stops if Troom ≥ Tset
In any case activation of the zone valve is subject to 3 minutes delay each time
it stops.

TIPS FOR BEST USE
ENERGY SAVING
AUTO
The writings COOL and HEAT appear on the display simultaneously.
Temperature setting
The setting temperature can be set in the range of 18°C-30°C by pressing
button. The LCD on the display unit will show the setting temperature.
Louver swing
Press the button to start/stop louver swing.
SLEEP mode
Press the
SLEEP
key to activate the mode. The symbol will appear on the di-
splay. In cool air-conditioning mode, the temperature is automatically increased
by 1 °C after an hour. Similarly, in warm air-conditioning mode the temperature
is decreased by 1 °C after an hour.
- Connect the cassette to a dedicated power socket protected by a magnetother-
mal circuit breaker of suitable capacity for the electrical input of the appliance.
- When the water cassette starts or stops, especially in the heating mode, cre-
aking sounds may be heard. This is caused by thermal expansion of the unit
parts.
- Mist may sometimes be produced by the cassette for a few seconds in the co-
oling mode. This is quite normal and is caused by the difference in temperature
between the air
fl owing out of the appliance and the air in the room.
- Do not place heat sources near to the cassette as this could deform the plastic
parts.
- Do not insert objects into the air intakes or outlets when the cassette is in
operation.
- Do not place objects in a position that may obstruct the passage of the air into
the unit as this could affect appliance ef
fi ciency.
- Avoid opening and closing doors and windows: the continuous thermal transfer
hinders the unit’s production.
- Do not set a temperature that is too high (in heating mode) or too low (in
cooling mode).
- Avoid installing the unit where it is directly exposed to sunlight.
- Use the timed shutdown to prevent it from being left on unnecessarily.
- Use the
SLEEP function during the night.
