To compensate for this error, you may
need to add or minus the degrees
required to achieve the correct
temperature.
Example
: The temperature on the
O
display is 28.0 C, whereas the actual
O
temperature is 30.0 C. You will need to

set this parameter to 2.0 C, which
means that once out of the programming
parameter, the display will show the

Use UP/DOWN keys to set desired
value. In time it may be possible that the
display may be offset by a degree or so.
To change P5 parameter,

Example
: If this parameter is set at 3
minutes, the compressor will cut off at
the set temperature, but will not restart
for a minimum of 3 minutes, even if the
differential is achieved earlier. This

This parameter is used to protect the fan
from restarting in a short period of time
and can be set between 0 to 20 minutes.

Example :
If P7 is set to 30 Mins and

This is maximum amount of time allowed
for defrost. If set to 0, there will be no

Fact. Set
This is the amount of time at power on

Example :
If P9 parameter is 30 mins
then at power after 30 mins defrosting
will take place once.
parameter is good to protect the life of
the compressor when there are power
fluctuations and the compressor is
switched off and on within a few seconds.
