5-11 Defrost

The defrost process is controlled by a detection algorithm designed in order to mantain optimal
utilization of the heat pump capacity especially during negative outdoor temperature conditions.

• Compressor speed fixed
• Expansion valve opening fixed 
• Outdoor fan switched off 
• Indoor fan controlled by cold draft prevention
• Defrost valve switched on (open) 
• Reversing valve switched on (heating operation) 

NOTES:
• Minimum defrost time interval is 2 minutes 
• During HIGH POWER operation the defrost detection is ignored until this mode remains active 
• System exits defrost protection as soon as 14°C on the outdoor coil are detected and, in any case,
   if at least 12 minutes are elapsed from the start of the defrost cycle. 

5-12 I FEEL function

As standard configuration  the air conditioner operates detecting the room temperature through the sensor
equipped in the wireless remote controller (icon I FEEL shown on the display). This feature provides a
personalised environment since the temperature can be detected where the remote controller is located.
It is possible to de-activate this option pressing the I FEEL button on the remote controller.
In this case the I FEEL icon is no longer displayed and room temperature is detected through the sensor 
included in the indoor unit.

5-13 HI POWER mode

When this mode is active the internal fan speed is set automatically and the air conditioner operates,
for 15 minutes, at the maximum power. After 15 minutes from the selection the mode is automatically
switched off.
