5-11 Defrost
5.11.2 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.
System condition:
• 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.
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.
