6.2.3 About the heating operation
It may take longer to reach the set temperature for general heating
operation than for cooling operation.
The following operation is performed in order to prevent the heating
capacity from dropping or cold air from blowing.
Defrost operation
In heating operation, freezing of the outdoor unit's air cooled coil
increases over time, restricting the energy transfer to the outdoor
unit's coil. Heating capability decreases and the system needs to go
into defrost operation to be able to remove frost from the outdoor
unit’s coil. During defrost operation the heating capacity on the
indoor unit side will temporarily drop until defrosting is completed.
After defrosting, the unit will regain its full heating capacity.
The indoor unit will stop fan operation, the refrigerant cycle will
reverse and energy from inside the building will be used to defrost
the outdoor unit coil.
The indoor unit will indicate defrost operation on the display .
Hot start
In order to prevent cold air from blowing out of an indoor unit at the
start of heating operation, the indoor fan is automatically stopped.
The display of the user interface shows . It may take some time
before the fan starts. This is not a malfunction.
