GENERAL INFORMATION
THERMOSTAT UNDER MICROCOMPUTER CONTROL
The thermostat being controlled by microcomputer allows remarkable energy saving and provides
more comfort, as the room temperature is checked with the greatest precision.
INDOOR FAN AUTOMATIC SPEED CONTROL
The airflow from the Indoor Unit can be controlled step by step, on the basis of the difference
between the room temperature and the set temperature. This allows to reduce the lapse of
time needed to reach the desired temperature both in Cooling and Heating mode, by treating
the appropriate air volumes.
AUTORESTART AFTER A POWER FAILURE
• When a power failure occurs during operation, the air conditioner immediately stops.
• When power is restored, “OPERATION” lamp starts blinking. In particular, the air conditioner
will automatically restart after 3 minutes have elapsed since power is restored. This means that
it is not required to press “ON/OFF” button on the remote controller. The settings will be the
same as before the blackout.
DIAGNOSTIC & PROTECTIVE FUNCTIONS
Shown by codifed flashing of LED indicators on the Indoor Unit, they allow to diagnose in a quite
procise way the main malfunctions which may concern the air conditioner.
3-minutes’ delay protection: there is a protective control of the Outdoor Unit, to prevent
compressor’s damages after stops. This control is effective in case of malfunction, power failure,
turning off the system, etc. and it does not allow Outdoor Unit to restart before 3 minutes have
elapsed since the Unit stopped. During this time, Indoor Unit cannot run.
