FUNCTIONS
1 System operation control
The units receives the user input (fan speed, flap position etc) through remote controller
which sends signal every time a button is pressed and in any case, automatically, every 5 minutes
.
During operation compressor speed can be subjected to change due to thermal load variations
or protection activations but in any case:
• The minimum time interval between an OFF and a ON operation is not lower than 3 minutes
• The minimum operating time is not lower than 3 minutes
• The maximum acceleration/deceleration rate is fixed at 20rpm /sec
• During the start-up compressor speed increases according to a defined rule which is
independent from the thermal load calculation.
2 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by:
1) the difference between the room air temperature (RAT) and the set point temperature (SPT)
2) the protection level at which the system is operatin
g
3) the thermal load in the room
NOTES
In addition to the temperature difference of above, the operation of the main components (CM, FMO,
FMI) is also controlled by protection function.
The minimum off time of compressor is 3 minutes.
The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).
3 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation. The CM, FMO and FMI are
controlled by the same parameters.
The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cold air (see COLD DRAFT PREVENTION feature for details).
The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).

4 Auto Mode Operation
In Auto Mode, the unit switches automatically between the Auto Cooling and Auto Heating in order to
maintain the room temperature (RAT) at the prescribed set point (SPT).
The switching between the two modes is according to the above graph and following table
If -3°C ≤Dt ≤-1°C and the compressor is off for more than 1 hour
If Dt ≤-3°C and compressor is off for more than 3 minutes
If 1°C ≤Dt ≤3°C and the compressor is off for more than 1 hour
If Dt ≥3°C and compressor is off for more than 3 minutes
Dt = RAT - SPT
Refer to the sections 1 COOLING MODE and 2 HEATING MODE for system operation details.
