Enable
Normal
Can be set when OFF or during operation
To reduce the room temperature increase by setting the LEV opening lower for the units in thermo-OFF
operation.
The refrigerant is more likely to collect in the units with thermo-OFF operation, and causing the units refrigerant shortage. (Results in less capacity and increase of discharge temperature.)

Change of defrosting control
Enable (For high humidity)
Normal
Can be set when OFF or during operation
To shorten the defrosting prohibition time in high humidity (or heavy snow) region, in order to reduce malfunctions caused by frost .
The performance of the HEA
T operation is somewhat
reduced since the defrosting operation is frequently performed.
5
Ignore
refrigerant
filling
abnormality
Enable
Normal
To ignore the error detection of excessive charge of refrigerant.
The unit can be excessively charged w
ith
refrigerant depending on the operating condition.
Make sure that the unit is not excessively charged with refrigerant before starting operation when servicing or installing the units.
6
Switching the target discharge pressure (Pdm)
Enable
Normal
To raise the performance by setting the PDm higher during HEA
T operation.
Power consumption is raised due to a higher frequency
. (The performance would not be raise at the
maximum operating frequency
.)
7
Switching (1) the target evaporation temperature (ETm)
Enable
Normal
To raise/reduce the performance by changing the target ETm during COOL
operation.
Switch to raise the performance: raises the performance Switch to reduce the performance: prevents dew condensation
Switching it to raise the performance, it raises the power
consumption, and produces more dew condensation. Switching it to reduce the performance, it makes the
performance insufficient.
