Function: To set Control (Main) Probe Calibration.
In time it may be possible that the display may be offset
by a degree or so.
To compensate for this error, user may need to add or
minus the degrees required to achieve the correct
Temperature.
Example:
The Temperature on the display is 28.0°C, whereas the
actual Temperature is 30.0°C. User will have to set the P5
Parameter to 2, which means that once out of the
Programming Mode, the Temperature on display will be
30.0°C (28.0°C + 2.0°C).

Function: To Set Time Delay between Compressor Relay
Restart.
This parameter is used to protect the Compressor from
restarting in a short period of time.
Example: If this parameter is set at 3 minutes, the
Compressor Relay goes OFF at the Set Point, it will not
restart for a minimum of 3 minutes, even if the
differential is achieved earlier. This parameter is good to
protect the life of the Compressor.

Function: Minimum ON Time for Compressor Relay.
This parameter is used to protect the Compressor so that
there is enough time for oil to return back to the
Compressor. This delay starts once the Compressor Relay
is ON.
Example: If this parameter is set at 2 minutes, then the
Compressor Relay will remain ON for minimum 2 minutes,
though Set Point is achieved.
